Improve Non_Unique_Primary_Key error, split file format detection into read/write, improve SQLite format detection (#6604)
Closes #6437
Related to #6410

- Add example duplicate row to `Non_Unique_Primary_Key`.
- Ensure `File.read` fails if the file does not exist, always.
- Ensure SQLite fails if file is empty or nonexistent or malformed.
- Split file format detection into read and write modes, so that the read mode can depend on actual file _contents_.

tokenize_to_columns or parse_to_columns results in a single column we shouldn't add the 1 (#6607)
When generating new column names in tokenize/split_to_columns, if there's only one new column, use the deleted input column name and don't add disambiguating integers after it.

Small changes from Book Club issues (#6533)
- Add dropdown to tokenize and split `column`.
- Remove the custom `Join_Kind` dropdown.
- Adjust split and tokenize names to start numbering from 1, not 0.
- Add JS_Object serialization for Period.
- Add `days_until` and `until` to `Date`.
- Add `Date_Period.Day` and create `next` and `previous` on `Date`.
- Use simple names with `File_Format` dropdown.
- Avoid using `Main.enso` based imports in `Standard.Base.Data.Map` and `Standard.Base.Data.Text.Helpers`.
- Remove an incorrect import from `Standard.Database.Data.Table`.

From #6587:

A few small changes, lots of lines because this affected lots of tests:
- `Table.join` now defaults to `Join_Kind.Left_Outer`, to avoid losing rows in the left table unexpectedly. If the user really wants to have an Inner join, they can switch to it.
- `Table.join` now defaults to joining columns by name not by index - it looks in the right table for a column with the same name as the first column in left table.
- Missing Input Column errors now specify which table they refer to in the join.
- The unique name suffix in column renaming / default column names when loading from file is now a space instead of underscore.

Proper implementation of Value Types in Table (#6073)
This is the first part of the #5158 umbrella task. It closes #5158, follow-up tasks are listed as a comment in the issue.

- Updates all prototype methods dealing with `Value_Type` with a proper implementation.
- Adds a more precise mapping from in-memory storage to `Value_Type`.
- Adds a dialect-dependent mapping between `SQL_Type` and `Value_Type`.
- Removes obsolete methods and constants on `SQL_Type` that were not portable.
- Ensures that in the Database backend, operation results are computed based on what the Database is meaning to return (by asking the Database about expected types of each operation).
- But also ensures that the result types are sane.
- While SQLite does not officially support a BOOLEAN affinity, we add a set of type overrides to our operations to ensure that Boolean operations will return Boolean values and will not be changed to integers as SQLite would suggest.
- Some methods in SQLite fallback to a NUMERIC affinity unnecessarily, so stuff like `max(text, text)` will keep the `text` type instead of falling back to numeric as SQLite would suggest.
- Adds ability to use custom fetch / builder logic for various types, so that we can support vendor specific types (for example, Postgres dates).

# Important Notes
- There are some TODOs left in the code. I'm still aligning follow-up tasks - once done I will try to add references to relevant tasks in them.

Detect conflicts between exported types and FQNs (#5986)
Exporting types named the same as the module where they are defined in `Main` modules of library components may lead to accidental name conflicts. This became apparent when trying to access `Problem_Behavior` module via a fully qualified name and the compiler rejected it. This is due to the fact that `Main` module exported `Error` type defined in `Standard.Base.Error` module, thus making it impossible to access any other submodules of `Standard.Base.Error` via a fully qualified name.

This change adds a warning to FullyQualifiedNames pass that detects any such future problems.
While only `Error` module was affected, it was widely used in the stdlib, hence the number of changes.

Closes #5902.

# Important Notes
I left out the potential conflict in micro-distribution, thus ensuring we actually detect and report the warning.

Fix cross_tab column naming edge cases, add fill_empty (#5863)
Closes #5151 and adds some additional tests for `cross_tab` that verify duplicated and invalid names.

I decided that for empty or `Nothing` names, instead of replacing them with `Column` and implicitly losing connection with the value that was in the column, we should just error on such values.

To make handling of these easier, `fill_empty` was added allowing to easily replace the empty values with something else.

Also, `{is,fill}_missing` was renamed to `{is,fill}_nothing` to align with `Filter_Condition.Is_Nothing`.

Add Comparator conversion for all types (#4067)
Add `Comparator` type class emulation for all types. Migrate all the types in stdlib to this new `Comparator` API. The main documentation is in `Ordering.enso`.

Fixes these pivotals:
- https://www.pivotaltracker.com/story/show/183945328
- https://www.pivotaltracker.com/story/show/183958734
- https://www.pivotaltracker.com/story/show/184380208

# Important Notes
- The new Comparator API forces users to specify both `equals` and `hash` methods on their custom comparators.
- All the `compare_to` overrides were replaced by definition of a custom _ordered_ comparator.
- All the call sites of `x.compare_to y` method were replaced with `Ordering.compare x y`.
- `Ordering.compare` is essentially a shortcut for `Comparable.from x . compare x y`.
- The default comparator for `Any` is `Default_Unordered_Comparator`, which just forwards to the builtin `EqualsNode` and `HashCodeNode` nodes.
- For `x`, one can get its hash with `Comparable.from x . hash x`.
- This makes `hash` as _hidden_ as possible. There are no other public methods to get a hash code of an object.
- Comparing `x` and `y` can be done either by `Ordering.compare x y` or `Comparable.from x . compare x y` instead of `x.compare_to y`.

- New `set` function design - takes a `Column` and works with that more easily and supports control of `Set_Mode`.
- New simple `parse` API on `Column`.
- Separated expression support for `filter` to new `filter_by_expression` on `Table`.
- New `compute` function allowing creation of a column from an expression.
- Added case sensitivity argument to `Column` based on `starts_with`, `ends_with` and `contains`.
- Added case sensitivity argument to `Filter_Condition` for `Starts_With`, `Ends_With`, `Contains` and `Not_Contains`.
- Fixed the issue in JS Table visualisation where JavaScript date was incorrectly set.
- Some dynamic dropdown expressions - experimenting with ways to use them.
- Fixed issue with `.pretty` that wasn't escaping `\`.
- Changed default Postgres DB to `postgres`.
- Fixed SQLite support for starts_with, ends_with and contains to be consistent (using GLOB not LIKE).

Division in Columns within InDB is integer based if both columns are integers (#4057)
Fixes https://www.pivotaltracker.com/story/show/184073099

# Important Notes
- Since now the only operator on columns for division, `/`, returns floats, it may be worth creating an additional `div` operator exposing integer division. But that will be done as a separate task aligning column operator APIs.

Database Joins (#4007)
Implements https://www.pivotaltracker.com/story/show/184032869

# Important Notes
- Currently we get failures in Full joins on Postgres which show a more serious problem - amending equality to ensure that `[NULL = NULL] == True` breaks hash/merge based indexing - so such joins will be extremely inefficient. All our joins currently rely on this notion of equality which will mean all of our DB joins will be extremely inefficient.
- We need to find a solution that will support nulls and still work OK with indices (but after exploring a few approaches: `COALESCE(a = b, a IS NULL AND b is NULL)`, `a IS NOT DISTINCT FROM b`, `(a = b) OR (a IS NULL AND b is NULL)`; all of which did not work (they all result in `ERROR: FULL JOIN is only supported with merge-joinable or hash-joinable join conditions`) I'm less certain that it is possible. Alternatively, we may need to change the NULL semantics to align it with SQL - this seems like likely the simpler solution, allowing us to generate simple, reliable SQL - the NULL=NULL solution will be cornering us into nasty workarounds very dependent on the particular backend.

Let JavaScript parse JSON and write JSON ... (#3987)
Use JavaScript to parse and serialise to JSON. Parses to native Enso object.
- `.to_json` now returns a `Text` of the JSON.
- Json methods now `parse`, `stringify` and `from_pairs`.
- New `JSON_Object` representing a JavaScript Object.
- `.to_js_object` allows for types to custom serialize. Returning a `JS_Object`.
- Default JSON format for Atom now has a `type` and `constructor` property (or method to call for as needed to deserialise).
- Removed `.into` support for now.
- Added JSON File Format and SPI to allow `Data.read` to work.
- Added `Data.fetch` API for easy Web download.
- Default visualization for JS Object trunctes, and made Vector default truncate children too.

Fixes defect where types with no constructor crashed on `to_json` (e.g. `Matching_Mode.Last.to_json`.
Adjusted default visualisation for Vector, so it doesn't serialise an array of arrays forever.
Likewise, JS_Object default visualisation is truncated to a small subset.

New convention:
- `.get` returns `Nothing` if a key or index is not present. Takes an `other` argument allowing control of default.
- `.at` error if key or index is not present.
- `Nothing` gains a `get` method allowing for easy propagation.

- Add `empty_object`, `empty_array`. `get_or_else`, `at`, `field_names` and `length` to `Json`.
- Fix `Json` serialisation of NaN and Infinity (to "null").
- Added `length`, `at` and `to_vector` to Pair (allowing it to be treated as a Vector).
- Added `running_fold` to the `Vector` and `Range`.
- Added `first` and `last` to the `Vector.Builder`.
- Allow `order_by` to take a single `Sort_Column` or have a mix of `Text` and `Sort_Column.Name` in a `Vector`.
- Allow `select_columns_helper` to take a `Text` value. Allows for a single field in group_by in cross_tab.
- Added `Patch` and `Custom` to HTTP_Method.
- Added running `Statistic` calculation and moved more of the logic from Java to Enso. Performance seems similar to pure Java version now.

- Clean up some odd syntaxes that the old parser translates idiosyncratically.
- Constructors are now required to precede methods.

# Important Notes
Out of 221 files:
- 215 match the old parser
- 6 contain complex types the old parser is known not to handle correctly

So, compared to the old parser, the new parser parses 103% of files correctly.

Adding a shorthand for the Table API until widgets available (#3753)
Allows using `Vector ColumnName` for the various table functions as short hand.

- `select_columns`, `remove_columns`,`reorder_columns`, `distinct` all map to an exact By_Name match.
- `rename_columns` does a positional rename on the Vector passed.
- `order_by` sorts ascending on each column passed in order.

# Important Notes
This may be reversed once widgets are available and working but this makes the APIs much more usable in current UI.

By-type pattern matching (#3742)
This change brings by-type pattern matching to Enso.
One can pattern match on Enso types as well as on polyglot types.

For example,
```
case x of
_ : Integer -> ...
_ : Text -> ...
_ -> ...
```
as well as Java's types
```
case y of
_ : ArrayList -> ...
_ : List -> ...
_ : AbstractList -> ...
_ -> ..
```

It is no longer possible to match a value with a corresponding type constructor.
For example
```
case Date.now of
Date -> ...
```
will no longer match and one should match on the type (`_ : Date`) instead.
```
case Date of
Date -> ...
```
is fine though, as requested in the ticket.

The change required further changes to `type_of` logic which wasn't dealing well with polyglot values.

Implements https://www.pivotaltracker.com/story/show/183188846

# Important Notes
~I discovered late in the game that nested patterns involving type patterns, such as `Const (f : Foo) tail -> ...` are not possible due to the old parser logic.
I would prefer to add it in a separate PR because this one is already getting quite large.~ This is now supported!

Implement type_of (#3722)
This change implements a simple `type_of` method that returns a type of a given value, including for polyglot objects.

The change also allows for pattern matching on various time-related instances. It is a nice-to-have on its own, but it was primarily needed here to write some tests. For equality checks on types we currently can't use `==` due to a known _feature_ which essentially does wrong dispatching. This will be improved in the upcoming statics PR so we agreed that there is no point in duplicating that work and we can replace it later.

Also, note that this PR changes `Meta.is_same_object`. Comparing types revealed that it was wrong when comparing polyglot wrappers over the same value.

Don't rename imported Main module that only imports names (#3710)
Turns that if you import a two-part import we had special code that would a) add Main submodule b) add an explicit rename.

b) is problematic because sometimes we only want to import specific names.
E.g.,
```
from Bar.Foo import Bar, Baz
```
would be translated to
```
from Bar.Foo.Main as Foo import Bar, Baz
```
and it should only be translated to
```
from Bar.Foo.Main import Bar, Baz
```

This change detects this scenario and does not add renames in that case.

Changes following Marcin's work. Should be back to very similar public API as before.

- Add an "interface" type: `Standard.Base.System.File_Format.File_Format`.
- All `File_Format` types now have a `can_read` method to decide if they can read a file.
- Move `Standard.Table.IO.File_Format.Text.Text_Data` to `Standard.Base.System.File_Format.Plain_Text_Format.Plain_Text`.
- Move `Standard.Table.IO.File_Format.Bytes` to `Standard.Base.System.File_Format.Bytes`.
- Move `Standard.Table.IO.File_Format.Infer` to `Standard.Base.System.File_Format.Infer`. **(doesn't belong here...)**
- Move `Standard.Table.IO.File_Format.Unsupported_File_Type` to `Standard.Base.Error.Common.Unsupported_File_Type`.
- Add `Infer`, `File_Format`, `Bytes`, `Plain_Text`, `Plain_Text_Format` to `Standard.Base` exports.
- Fold extension methods of `Standard.Base.Meta.Unresolved_Symbol` into type.
- Move `Standard.Table.IO.File_Format.Auto` to `Standard.Table.IO.Auto_Detect.Auto_Detect`.
- Added a `types` Vector of all the built in formats.
- `Auto_Detect` asks each type if they `can_read` a file.
- Broke up and moved `Standard.Table.IO.Excel` into `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Excel.Excel_Data` to `Standard.Table.Excel.Excel_Format.Excel_Format.Excel`.
- Renamed `Sheet` to `Worksheet`.
- Internal types `Reader` and `Writer` providing the actual read and write methods.
- Created `Standard.Table.Delimited` with similar structure to `Standard.Table.Excel`:
- Moved `Standard.Table.IO.File_Format.Delimited.Delimited_Data` to `Standard.Table.Delimited.Delimited_Format.Delimited_Format.Delimited`.
- Moved `Standard.Table.IO.Quote_Style` to `Standard.Table.Delimited.Quote_Style`.
- Moved the `Reader` and `Writer` internal types into here. Renamed methods to have unique names.
- Add `Aggregate_Column`, `Auto_Detect`, `Delimited`, `Delimited_Format`, `Excel`, `Excel_Format`, `Sheet_Names`, `Range_Names`, `Worksheet` and `Cell_Range` to `Standard.Table` exports.

- `SQLite_Connection` has the `Connection` API but with custom `databases` and `schemas` methods for SQLite.
- `Postgres_Connection` has the `Connection` API but with custom `set_database`, `databases`, `set_schema` and `schemas` methods for Postgres.

Add Table.distinct function to In-Memory table (#3684)
Implements https://www.pivotaltracker.com/story/show/182307143

# Important Notes
- Modified standard library Java helpers dependencies so that `std-table` module depends on `std-base`, as a provided dependency. This is allowed, because `std-table` is used by the `Standard.Table` Enso module which depends on `Standard.Base` which ensures that the `std-base` is loaded onto the classpath, thus whenever `std-table` is loaded by `Standard.Table`, so is `std-base`. Thus we can rely on classes from `std-base` and its dependencies being _provided_ on the classpath. Thanks to that we can use utilities like `Text_Utils` also in `std-table`, avoiding code duplication. Additional advantage of that is that we don't need to specify ICU4J as a separate dependency for `std-table`, since it is 'taken' from `std-base` already - so we avoid including it in our build packages twice.

Make In Memory Table Aggregator types more specific where possible (#3679)
Many aggregation types fell back to the general `Any` type where they could have used the type of input column - for example `First` of a column of integers is guaranteed to fit the `Integer` storage type, so it doesn't have to fall back to `Any`.

Get rid of free-floating atoms. Everything has a type now! (#3671)
This is a step towards the new language spec. The `type` keyword now means something. So we now have
```
type Maybe a
Some (from_some : a)
None
```
as a thing one may write. Also `Some` and `None` are not standalone types now – only `Maybe` is.
This halfway to static methods – we still allow for things like `Number + Number` for backwards compatibility. It will disappear in the next PR.

The concept of a type is now used for method dispatch – with great impact on interpreter code density.

Some APIs in the STDLIB may require re-thinking. I take this is going to be up to the libraries team – some choices are not as good with a semantically different language. I've strived to update stdlib with minimal changes – to make sure it still works as it did.

It is worth mentioning the conflicting constructor name convention I've used: if `Foo` only has one constructor, previously named `Foo`, we now have:
```
type Foo
Foo_Data f1 f2 f3
```

This is now necessary, because we still don't have proper statics. When they arrive, this can be changed (quite easily, with SED) to use them, and figure out the actual convention then.

I have also reworked large parts of the builtins system, because it did not work at all with the new concepts.

It also exposes the type variants in SuggestionBuilder, that was the original tiny PR this was based on.

PS I'm so sorry for the size of this. No idea how this could have been smaller. It's a breaking language change after all.

Builtin Date_Time, Time_Of_Day, Zone (#3658)
* Builtin Date_Time, Time_Of_Day, Zone

Improved polyglot support for Date_Time (formerly Time), Time_Of_Day and
Zone. This follows the pattern introduced for Enso Date.

Minor caveat - in tests for Date, had to bend a lot for JS Date to pass.
This is because JS Date is not really only a Date, but also a Time and
Timezone, previously we just didn't consider the latter.
Also, JS Date does not deal well with setting timezones so the trick I
used is to first call foreign function returning a polyglot JS Date,
which is converted to ZonedDateTime and only then set the correct
timezone. That way none of the existing tests had to be changes or
special cased.

Additionally, JS deals with milliseconds rather than nanoseconds so
there is loss in precision, as noted in Time_Spec.

* Add tests for Java's LocalTime

* changelog

* Make date formatters in table happy

* PR review, add more tests for zone

* More tests and fixed a bug in column reader

Column reader didn't take into account timezone but that was a mistake
since then it wouldn't map to Enso's Date_Time.
Added tests that check it now.

* remove redundant conversion

* Update distribution/lib/Standard/Base/0.0.0-dev/src/Data/Time.enso

Support module imports using a qualified name (#3608)
This change allows for importing modules using a qualified name and deals with any conflicts on the way.
Given a module C defined at `A/B/C.enso` with
```
type C
type C a
```
it is now possible to import it as
```
import project.A
...
val x = A.B.C 10
```

Given a module located at `A/B/C/D.enso`, we will generate
intermediate, synthetic, modules that only import and export the successor module along the path.
For example, the contents of a synthetic module B will look like
```
import <namespace>.<pkg-name>.A.B.C
export <namespace>.<pkg-name>.A.B.C
```
If module B is defined already by the developer, the compiler will _inject_ the above statements to the IR.

Also removed the last elements of some lowercase name resolution that managed to survive recent
changes (`Meta.Enso_Project` would now be ambiguous with `enso_project` method).

Finally, added a pass that detects shadowing of the synthetic module by the type defined along the path.
We print a warning in such a situation.

Related to https://www.pivotaltracker.com/n/projects/2539304

# Important Notes
There was an additional request to fix the annoying problem with `from` imports that would always bring
the module into the scope. The changes in stdlib demonstrate how it is now possible to avoid the workaround of
```
from X.Y.Z as Z_Module import A, B
```
(i.e. `as Z_Module` part is almost always unnecessary).

Explicit self (#3569)
This change modifies the current language by requiring explicit `self` parameter declaration
for methods. Methods without `self` parameter in the first position should be treated as statics
although that is not yet part of this PR. We add an implicit self to all methods
This obviously required updating the whole stdlib and its components, tests etc but the change
is pretty straightforward in the diff.

Notice that this change **does not** change method dispatch, which was removed in the last changes.
This was done on purpose to simplify the implementation for now. We will likely still remove all
those implicit selfs to bring true statics.
Minor caveat - since `main` doesn't actually need self, already removed that which simplified
a lot of code.

Significantly improves the polyglot Date support (as introduced by #3374). It enhances the `Date_Spec` to run it in four flavors:
- with Enso Date (as of now)
- with JavaScript Date
- with JavaScript Date wrapped in (JavaScript) array
- with Java LocalDate allocated directly

The code is then improved by necessary modifications to make the `Date_Spec` pass.

# Important Notes
James has requested in [#181755990](https://www.pivotaltracker.com/n/projects/2539304/stories/181755990) - e.g. _Review and improve InMemory Table support for Dates, Times, DateTimes, BigIntegers_ the following program to work:
```
foreign js dateArr = """
return [1, new Date(), 7]

main =
IO.println <| (dateArr.at 1).week_of_year
```
the program works with here in provided changes and prints `27` as of today.

@jdunkerley has provided tests for proper behavior of date in `Table` and `Column`. Those tests are working as of [f16d07e](f16d07e640). One just needs to accept `List<Value>` and then query `Value` for `isDate()` when needed.

Last round of changes is related to **exception handling**. 8b686b12bd makes sure `makePolyglotError` accepts only polyglot values. Then it wraps plain Java exceptions into `WrapPlainException` with `has_type` method - 60da5e70ed - the remaining changes in the PR are only trying to get all tests working in the new setup.

The support for `Time` isn't part of this PR yet.

Remove 'here' and make method name resolution case-sensitive (#3538)
Modified UppercaseNames to now resolve methods without an explicit `here` to point to the current module.
`here` was also often used instead of `self` which was allowed by the compiler.
Therefore UppercaseNames pass is now GlobalNames and does some extra work -
it translated method calls without an explicit target into proper applications.

# Important Notes
There was a long-standing bug in scopes usage when compiling standalone expressions.
This resulted in AliasAnalysis generating incorrect graphs and manifested itself only in unit tests
and when running `eval`, thus being a bit hard to locate.
See `runExpression` for details.

Additionally, method name resolution is now case-sensitive.

Obsolete passes like UndefinedVariables and ModuleThisToHere were removed. All tests have been adapted.

Implements https://www.pivotaltracker.com/story/show/181805693 and finishes the basic set of features of the Aggregate component.

Still not all aggregations are supported everywhere, because for example SQLite has quite limited support for aggregations. Currently the workaround is to bring the table into memory (if possible) and perform the computation locally. Later on, we may add more complex generator features to emulate the missing aggregations with complex sub-queries.
