- Abseil
- Protobuf
- Benchmark
- Googletest
In turn, some code changes were necessary:
- Use absolute imports in `sapi_generator.py` when invoked by Bazel
- Add Abseil's source dir as include dir in generated proto `.cc` files
- Bazel: Use `@rules_proto` for `proto_library` and use native `cc_proto_library`
Drive-by:
- Update year in `README.md`
- Look for clang versions 16, 15, 14, and 13 as well in `code.py`

This updates the mininum required version of CMake to 3.13, which is
present in Debian Buster.
At the same time, move all of our dependency handling to use
`FetchContent_Declare()`, `FetchContent_Populate()` and
`FetchContent_MakeAvailable()`. Since the latter was ony introduced in
3.14, provide a simple "polyfill" implementation for that.
As an added benefit, the configure step for libffi and libunwind will
now not be re-run every time the `CMakeLists.txt` changes.
Other changes:
- Explicitly spell out that we're testing up to 3.22 in
`cmake_minimum_version()`
- Rename `check_target()` to `sapi_check_target()` to avoid conflicts
with Abseil.
The newer version includes a fix for a compilation error on newer
systems (specfically, `benchmark_register.h` was missing an include
for the `limits` header).
