* replaces Dockerfile using bazel-based build system
This commit updates the Dockerfile to work with anki's bazel-based build
system.
The anki Dockerfile was originally added in
https://github.com/ankitects/anki/pull/753 back in September 2020. The
file was moved to `docs/Dockerfile` in
0d354da93a, with a note that the file had
to be updated to work with anki's updated build system. The file
`docs/Dockerfile` was removed in
7cd2e9618f.
* install setuptools and wheel + xkb libraries
* install anki virtual env in fresh base image
* move Dockerfile out of root directory
* add readme file for dockerized anki
Recommend removing ts/node_modules folder before attempting to
build after this update.
This moves ts/node_modules into the root of the project to work around

Also fixes the sass errors shown when running scripts/svelte-check
With proper excludes set up, starting it outside of Bazel is similarly
fast, and unit tests work correctly. It also makes initial Bazel startup
faster, as the Rust sources no longer need to be fetched.
In order to split backend.proto into a more manageable size, the protobuf
handling needed to be updated. This took more time than I would have
liked, as each language handles protobuf differently:
- The Python Protobuf code ignores "package" directives, and relies
solely on how the files are laid out on disk. While it would have been
nice to keep the generated files in a private subpackage, Protobuf gets
confused if the files are located in a location that does not match
their original .proto layout, so the old approach of storing them in
_backend/ will not work. They now clutter up pylib/anki instead. I'm
rather annoyed by that, but alternatives seem to be having to add an extra
level to the Protobuf path, making the other languages suffer, or trying
to hack around the issue by munging sys.modules.
- Protobufjs fails to expose packages if they don't start with a capital
letter, despite the fact that lowercase packages are the norm in most
languages :-( This required a patch to fix.
- Rust was the easiest, as Prost is relatively straightforward compared
to Google's tools.
The Protobuf files are now stored in /proto/anki, with a separate package
for each file. I've split backend.proto into a few files as a test, but
the majority of that work is still to come.
The Python Protobuf building is a bit of a hack at the moment, hard-coding
"proto" as the top level folder, but it seems to get the job done for now.
Also changed the workspace name, as there seems to be a number of Bazel
repos moving away from the more awkward reverse DNS naming style.
- bumps rust version to 1.53
- drops support for incremental building, which is currently
disabled in stable Rust releases due to bugs. 'cargo check' can still
be used to quickly check things compile
Uses the logic from the sqltools VSCode add-on, with a workaround
for the use of 'type' in some table columns.
By detecting the presence of 'BUILD_WORKSPACE_DIRECTORY' we can tell
if the rule is running in test mode or was run directly, avoiding the
need for separate check and fix rules. It might be nice to extend this
to other formatting rules in the future as well.
