We've been observing some performance issues using crate_universe on CI.
Therefore, we're moving to vendor the auto-generated BUILD files
in our repository. This should provide a nice speed boost, while
getting rid of the complexity of the "rust cache" job we've been using
when we had a lot of git dependencies.
This PR includes a vendor script, and I'll put up a CI job internally
that runs that vendor script on Cargo.toml and Cargo.lock changes, to check
that the vendored files are in sync.
This should allow us to build our python and ruby
code independently - in particular, we can now do shallow
checkouts of one without the other.
Previously, the modext introduced cross-dependency.
This also reduces the amount of work we do in the
crate universe processing for the other language, even
though it's unused.
This does need renaming the module, as otherwise
the generated paths from rules_rust get too long
for Windows :(
This commits a bazel-based build system for C#
using `rules_dotnet`. External dependencies are managed
via `paket`, and updates to the generated bazel files
are done via `./update-deps.sh`.
We're providing our own (minimal) test runner for `xunit`
tests.
