The Python code has been relying on `spelling` to return `None` for skipping
anonymous structs/unions.
libclang has been returning a "spelling" for those for a while now (LLVM 16
introduced this in its branch in 2022), though, so this check no longer works.
Use the correct method `clang.CIndex.is_anonymous()` instead.

I believe it's possible for the `main_pid` to disappear between `kill` and `sigtimedwait` by means of an `exec` from a multithreaded process (`PTRACE_EVENT_EXIT` happens after the `exec`ing thread changes its tid to main_pid)

There is no strong reason why this shouln't be the case.
Some future refactorings will depend on this.

CRIU while restoring memfd sometimes reopens them, which might result in ETXTBUSY on execveat.

The `CreateMemFd` function sets the `MFD_ALLOW_SEALING` flag which enables seals to be set and creating an empty file seal.

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.

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.

- 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.

To avoid code that is being parsed to include the intrinsics headers, undefine
a few key preprocessor defines.

- 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`
