Based on usage; I believe this handles every case in current `.enso` files.
# Important Notes
- `import` is a built-in macro, so an import statement parses as a `MultiSegmentApp`.
- Every `import` syntax will have a segment whose leading keyword is `import`; however `import` macros can be identified more efficiently by looking at only the first keyword. A `MultiSegmentApp` is an import if and only if its first keyword is in the set { "polyglot", "from", "import" }.
Show custom icons in Component Browser for entries that have a non-empty `Icon` section in their docs with the section's body containing a name of a predefined icon.

# Important Notes
- The PR assigns icon names to four items in the standard library, but only three of them are shown in the Component Browser because of [a parsing bug in the Engine](https://www.pivotaltracker.com/story/show/182781673).
- Icon names are assigned only to four items in the standard library because only two currently predefined icons match entries in the currently defined Virtual Component Groups. Adjusting the definitions of icons and Virtual Component Groups is covered by [a different task](https://www.pivotaltracker.com/story/show/182584311).
- A bug in the documentation of the Enso protocol message `DocSection` is fixed. A `text` field in the `Tag` interface is renamed to `body` (this is the field name used in Engine).
This PR adds a new variant of selection, where the mouse-hovered entry is highlighted and may be selected by clicking.
In the video below, we have three grid views with slightly different settings:
* In the left-top corner, both hover and selection highlight is just a shape under the label. Such a grid view does not require additional layers (when compared to non-selectable grid view).
* In the left-bottom corner the hover is normal shape, but selection is a _masked layer_ which allows us to have different text color. This setting requires three more layers to render.
* In the right-top corner, both hover and selection are displayed in the masked layer, creating 6 additional layers.

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.

# 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).
This is a partial workaround for https://www.pivotaltracker.com/story/show/182713407
Because some entries' names are too long to be displayed inside the Component List Panel, the user may have no clue what the method is. Therefore, we add a title to each doc page.
There is also code introduced for displaying name of modules when submodule header is selected. However, it does not work, and it's hard to fix without significant changes in the Component List Panel API and implementation. Because those will be altered when implementing [Efficient Component List Panel](https://www.pivotaltracker.com/story/show/182561072), fixing is postponed until then.
# Important Notes
The code contains some significant refactoring. Removed long functions obtaining entries from the component::List - instead you can get group, and then entry from group. They return an option, which is turned to Result in the presenter (where we actually take advantage of having Result instead of Option).
Fixes random timeout failures on CI.
```
INFO ide_ci::program::command: sbtℹ️ up to date, audited 98 packages in 3s
```
`npm install` takes 3s of test time doing unnecessary package auditing. On CI the command is executed once before running the tests and redundant `npm install` calls can be omitted.
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.
Adds a Dockerfile and `CreatePostgresSSL.sh` script, which makes an Alpine based Postgres server with a self signed certificate. The script will drop the generated `rootCA.crt` into the `data/transient` folder.
This can then be included in the test by setting the environment variable `ENSO_DATABASE_TEST_CA_CERT_FILE`.
Test has been updated to check the various SSL connection modes.
Provide a JNI dynamic-library interface to `enso_parser`.
# Important Notes
- The library can be built with: `cargo build -p enso-parser-jni`.
- A new `org.enso.syntax2.Parser` API is implemented on top of the JNI interface provided by `enso-parser-jni`.
- We are using the `jni` crate, since apparently Java cannot just call C-ABI functions. The crate is not well-maintained. I came across an obviously-unsound `safe` function, and found it was reported over a year ago, with a PR to fix: jni-rs/jni-rs#303. However our needs are simple. We can't trust any safety guarantees they imply, but I think we are unlikely to encounter any logic bugs using the basic bindings.
Adds least squares regression APIs. Covers the basic 4 trend line types from Excel (doesn't cover Polynomial or Moving Average).
Removes the old `Model` from the `Standard.Table`.
Filter the Virtual Component Groups (a.k.a. "Favorites Data Science Tools") in the `component::List` (a.k.a. Hierarchical Action List) to only contain components with IDs listed in the Engine's response to a `search/completion` request.
This completes the "Virtual Component Groups filtered by input type" task (linked below) because the Engine's response to a `search/completion` request contains IDs of components filtered by input node type and `this` type.
https://www.pivotaltracker.com/story/show/182661634
#### Visuals
See below for a video showing the list of Favorites filtered by the type of the input node. Please note that the video also displays a few known issues that are present in the existing code and not introduced by this PR:
- "Opening the Component Browser 2nd or later time flashes its last contents from the previous time" - reported as [issue 15 in PR 3530](https://github.com/enso-org/enso/pull/3530#pullrequestreview-1035698205).
- The text of all the entries in the Component Browser does not show immediately, but the entries appear one by one instead (this is related to the performance of the current implementation of Component Browser and Text Area).

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.
**Note**: This PR also contains content of previous Grid View PR. We decided to discard the previous, because this one did some refactoring of old one, and it's not a big addition.
Added a scrollable::GridView component, which just embeds the GridView in ScrollArea. Also, re-worked the idea of text layers.

This PR contains all work for finishing integration of first Component List Panel in the IDE:
* It adds a stub for the whole Component Browser View. The documentation panel is re-used from the old searcher.
* It has the presenter implementation, integrating the view with Hierarchical Component List from the controller.
* It extends the View API, so the integration is possible, making use of Component Group Set wrapper.
* The selection integration was also merged into this PR, because it depended on the API extension mentioned above. However, we should avoid such practice in the future.
https://user-images.githubusercontent.com/3919101/177816427-8c4285b4-8941-4048-a400-52f4acf77a9f.mp4
# Important Notes
There are some known issues, to-be-fixed in the future.
* The performance is bad. It should be improved with new text::Area, and the decent one shall come with [GridView inside component browser](https://www.pivotaltracker.com/story/show/182561072)
* There is no keyboard navigation. It should also be delivered with [GridView](https://www.pivotaltracker.com/story/show/182561072).
* The Favorites section is not [filtered out by node source type](https://www.pivotaltracker.com/story/show/182661634).
Updates `write_bytes` API to be part of `Vector` and to conform to `write` APIs.
# Important Notes
Ensures doesn't touch the file if an invalid byte array.
Implements https://www.pivotaltracker.com/story/show/182633483
Adds functionality to the Searcher Controller to save the expression of a node to its metadata, while it is edited. In later PRs this will be used to restore the expression, if an edit is aborted. This will be needed, as the expression will be changed within the source while editing to allow the visualization preview to be shown. As of this PR, the information is only stored, not used yet.
Demo Video
------------------
Note how the metadata of the node includes a `edit_status` field, when the project is saved during editing, and how it is cleared when saving without an edit happening.

# Important Notes
[ci no changelog needed]
Add some additional scenarios to Excel append tests:
- Non-A1 start
- Name duplication
- Hitting another range
# Important Notes
Also fixed a warning in the Image library.
Visualization within the UI is no longer working since the removal of the `here` keyword.
This PR fixes the JavaScript calls.
# Important Notes
There are various lines of rust code which still have `here.` within them and these will need to be fixed at some point.
The option asks to print a final test report for each projects at the
end `sbt> run`.
That way, when running the task in aggregate mode, we have a summary at
the end, rather than somewhere in the large output of the individual
subproject.
Updated the SQLite, PostgreSQL and Redshift drivers.
# Important Notes
Updated the API for Redshift and proved able to connect without the ini file workaround.
There is an Unsafe.set_atom_field operation in Standard library. That operation allows one to create an infinite data structure. Store following program in ones.enso:
```
import Standard.Base.IO
import Standard.Base.Runtime.Unsafe
type Gen
type Empty
type Generator a:Int tail:Gen
ones : Gen
ones =
g = Generator 1 Empty
Unsafe.set_atom_field g 1 g
g
main =
IO.println here.ones
```
running such program then leads to (probably expectable) stack overflow exception:
```
Execution finished with an error: Resource exhausted: Stack overflow
at <enso> Any.to_text(Internal)
...
at <enso> Any.to_text(Internal)
at <enso> Any.to_text(Internal)
at <enso> Any.to_text(Internal)
at <enso> IO.println(Internal)
at <enso> g.main(g.enso:15:5-24)
```
However the bigger problem is that it also crashes our debugger. While producing guest Stack overflow when the guest program is running maybe OK, crashing the engine doesn't seem tolerable.
Try:
```
enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --inspect --run ones.enso
```
and navigate Chrome dev tools to the line 11 as shown on the attached picture.
Stepping over that line generates following error:
```

Stack overflow in the engine when computing `Atom.toString()` - I want to prevent that.
# Important Notes
I am able to see a stacktrace in the debugger and I can _step in_ and _step over_, @kustosz:
However there are extra items like `case_branch` which I'd like to avoid, would you know how to do that?
