Propagate `--crate-name` into `cc_bindings_from_rs`.

This CL is needed to support running `cc_bindings_from_rs` on any Rust
crate where the name of the crate is not based on the basename of the
crate root (the name of the main `.rs` file).

This CL can be seen as a *small* step toward replicating all `rustc`
cmdline arguments into the invocation of `cc_bindings_from_rs`.

This CL makes the following changes:

* Adds `--crate-name` propagation to
  `cc_bindings_from_rs/bazel_support/cc_bindings_from_rust_rule.bzl`
* Adds tests that exercise the `--crate-name` support and would fail
  without the change above: `cc_bindings_from_rs/test/bazel/crate_name`
* Moves tests from `cc_bindings_from_rs/test/bazel_unit_tests` to
  `cc_bindings_from_rs/test/bazel/unit_tests`.  This helps to keep
  the Bazel-focused tests under `cc_bindings_from_rs/test/bazel`.

Crubit: C++/Rust Bidirectional Interop Tool

Build status

Extremely experimental interop tooling for C++ and Rust.

Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.

Building Crubit

$ apt install clang lld bazel
$ git clone git@github.com:google/crubit.git
$ cd crubit
$ bazel build --linkopt=-fuse-ld=/usr/bin/ld.lld //rs_bindings_from_cc:rs_bindings_from_cc_impl

Using a prebuilt LLVM tree

$ git clone https://github.com/llvm/llvm-project
$ cd llvm-project
$ CC=clang CXX=clang++ cmake -S llvm -B build -DLLVM_ENABLE_PROJECTS='clang' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=install
$ cmake --build build -j
$ # wait...
$ cmake --install build
$ cd ../crubit
$ LLVM_INSTALL_PATH=../llvm-project/install bazel build //rs_bindings_from_cc:rs_bindings_from_cc_impl
