04ed89906b Adding AllowOpen to AllowLlvmSanitizers to avoid having to add AllowOpen in addition when it's only needed for running under the sanitizers.
In cases where SAPI users overwrite the default policy instead of extending it, the sandbox will fail with an `openat` violation. This is automatically inherited in the default policy.

The advantage with this implementation is that we don't expose the open* syscalls when not running under the sanitizers.

5dd7584e55 Propagate compatible_with through sapi_library.
If a sandboxing target sets a `compatible_with` constraint, the current sapi.bzl doesn't propagate this to the subsequent target generations.

We implement the forwarding similarly to the `visibility` attribute.

0463298780 Sandbox2: Improve logging of syscall information.
- If --sandbox2_danger_danger_permit_all_and_log is set, we write to a logfile (passed via the flag).

- If --sandbox2_danger_danger_permit_all is set, we do not write any log information.

This change introduces a means to also see the syscall information on stderr by passing --v=1 and --alsologtostderr.

045ace8dcb Update Google dependencies
- 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`

9299156727 CMake: Use toolchain info for system includes
CMake already provides `CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES`, so there's
no need to invoke the compiler to determine system include directories.

For the Clang tool based header generator, adding the includes from the
current toolchain is strictly more correct than having it try and figure them
out itself (which will favor files from any installed libc++ and/or Clang).

5b12071ba0 Remove WaitForSanitizers from ptrace monitor & add to global forkserver
This makes should ensure global forkserver will be single threaded before forking the sandboxees as it does not go through WaitAndFork.

Waiting for sanitizers is not needed in the monitor and should reduce latency
by 1 second for all sanitizer builds. Currently it'll always wait up to 1 seconds for the process to become single-threaded, which will never happen as monitor itself is running in a separate thread.
