Fix a DROP table bug, add SQL debug logging (#8007)
- Fixes a bug where creating a temporary table could accidentally issue a `DROP` statement of the table name that the user provided, risking destruction of user data.
- Fortunately, the bad scenario was almost impossible, because the `DROP` statement was only issued _if_ we previously checked that the mentioned table _does not exist_ - dropping a nonexistent table does not do any harm.
- It could have been dangerous in a very unlikely scenario that a table was created just between the _existence check_ and the _drop_.
- After the fix the existence check and any modifications are done within a transaction to avoid interference from concurrent modifications, and the DROP is correctly applied to a temporary Enso table instead of the original one.
- Replaced a temporary log with proper simple logging of SQL statements into a file, if an Environment variable is set.
- Used that feature to test that no unexpected statements occur.

Using conversions in a few places (#7859)
- Shuffle a few `from`s into correct places:
- `Day_Of_Week.from` removing `Day_Of_Week_From` module.
- Adding short cut for `http` and `https` in `Data.read` so it calls onto `Data.fetch` giving a single entry point.
- Moved `URI` extensions from `Standard.Base.Data` module into `Standard.Base.Network.Extensions`.
- Added `post` extension for `URI`.
- Added `contains_key` to `JS_Object`.
- Restored `into` in `JS_Object`:
- Follows old logic populating a constructor.
- Will use conversion from `JS_Object` if present.
- Added automatic deserialization of `Date`, `Time_Of_Day` and `Date_Time` from JSON.
- Uses conversion from `JS_Object`.
- Added conversion from `Text` to a `HTTP_Method` and type checking where `HTTP_Method` used in public APIs.
- Added support for `Date`, `Time_Of_Day` and `Date_Time` in `Table.from_objects`.
- Added `expand_column` to `Table` to expand `JS_Object` to values.
- Add type checking for `Table` in `right` arguments (allowing `Column`s to be used).
- Use type checking in `Table.set` to allow for conversion to a `Column`.
- Remove some unused imports.
- Fix for bug in S3 edge case.

S3 Read Access, Input Stream based reading (#7776)
- Added a `FileSystemSPI` allowing protocol resolution to a target type.
- Separated `Input_Stream` and `Output_Stream` from `File` to allow use in other spaces.
- `File_Format` types `read_web` changed to be `read_stream` working with `InputStream`.
- Added directory listing to `Auto_Detect` allowing for `Data.read` to list a folder.
- Adjusted HTTP to return an `InputStream` not a `byte[]`:
- `Response_Body` adjusted to wrap an `InputStream`.
- Added ability to materialize to either and in-memory vector (<4KB) or a temporary file.
- `Data.fetch` will materialize if not a recognized mime-type.
- Added `HTTP_Error` to handle IO exceptions from the stream.
- `Excel_Format` now supports mime-type and reading a stream.
- `Excel_Workbook` can now get a `Excel_Section` using `read_section`.
- Added S3 APIs:
- `parse_uri`: splits an S3 URI into bucket and key.
- `list_objects`: list the items in a S3 bucket with specified prefix.
- `read_bucket`: list prefixes and keys with a delimiter in a S3 bucket with specified prefix.
- `head`: either head_bucket (tests existance) or head_object API (reads object meta data).
- `get_object`: gets an object from S3 returning as a `Response_Body`.
- Added `S3_File` type acting like a `File`:
- No support for writing in this PR.
- **ToDo:** recursive listing, glob filtering, exists, size.
- Fixed a few invalid type signature line.
- Moved `create` methods for `Postgres_Connection` and `SQLite_Connection` into type instead of module.
- Renamed `Column_Fetcher.Builder` to `Column_Fetcher_Builder`.
- Fixed bug with `select_into` in Dry Run mode creating permanent tables.

**ToDo:** Unit tests.

Add GROUP to functions (#7622)
- Update list of groups to agreed list.
- Lower case `ALIAS` names to be consistent with function names.
- Add `GROUP` to methods.
- All constructors and functions have doc comments.
- Correct a few typos (e.g. `PRVIATE`).
- Mark some more things as `PRIVATE`.
- Use `ToDo:` and `Note:` consistently.
- Order tags in doc comment.

# Important Notes
We don't have all the doc comments on types and will want to add them in future,

Respect database backend naming limitations when generating table/column names and validate user-provided names to avoid silent name clashes; process JDBC warnings reported from backends (#7428)
- Closes #5951
- Ensures any SQL warnings reported by the database through the JDBC driver are processed and forwarded to the user.
- These warnings show issues like the implicit name truncation that this PR is also solving. It's good to make sure they are visible as they can help avoid and understand unexpected problems. They should not show up in most standard workflows.
- Adds simple history to our REPL.
