This is the first in a series of changes that will remove our custom logging
implementation in favor of the newly released Abseil log library.

When not requesting any particular function, `sapi_library()` will try and
make available _all_ functions it finds. In this case, system headers should
be skipped to avoid inflating the API surface. Standard library functions
can still be manually requested by adding them to the `functions` (Bazel)/
`FUNCTIONS` (CMake) argument.

If it isn't, assume that the process has exited and the event msg contains an exit code.

Instead of doing waitpid() and processing one thread at a time, gather all waiting threads and then process them.
This avoids starving older threads when newer threads raise a lot of events.

This finally prevents Ninja from rebuilding everything needlessly each time a
CMake reconfiguration was triggered. The root cause is that we used
`file(WRITE ...)`, which always unconditionally overwrites, so Ninja sees
those files as "dirty".

E.g. a failed `KillSandboxee` for a timeout would already set the exit status code while there could be an external kill pending at the same time which would try to `KillSandboxee` again and thus set exit status code again.

This should make multithreaded sandboxees that exec (or send `SIGKILL`) behave more reliably.

Instead of calling `google::InitGoogleLogging()` directly, introduce an
indirection via a new utility library. After this change, Sandboxed API
should consistently use `sapi::InitLogging()` everywhere.
For now, `sapi::InitLogging()` simply calls its glog equivalent. However,
this enables us to migrate away from the gflags dependency and use Abseil
flags. Once a follow-up change lands, `sapi::InitLogging()` will instead
initialize the google logging library with flags defined from Aseil.
Later still, once Abseil releases logging, we can then drop the glog
dependency entirely.

Also revert the `.bazelversion` file again, as this will enforce a fixed
version, not a minimum version, which does not work well with our BazelCI.

Internally, we rely on clang-tidy to warn about using deprecated declarations.
And for using deprecated declarations within SAPI itself, we should not warn.
Drive-by:
- Fix warning in `mounts_test.cc`

`BUILD_TESTING` is a CMake provided option and we should use similar naming,
just like how Abseil does it.
- `SAPI_ENABLE_TESTS` -> `SAPI_BUILD_TESTING`
- `SAPI_ENABLE_CONTRIB_TESTS` -> `SAPI_CONTRIB_BUILD_TESTING`
- `SAPI_ENABLE_EXAMPLES` -> `SAPI_BUILD_EXAMPLES`
Drive-by:
- Fix option name in GitHub action

Including the `CTest` modules ensures that the `BUILD_TESTING` option is
defined and automatically calls `enable_testing()` if needed. It does not
change the default or introduce any dependencies on its own.
This follows what Abseil already does in their top-level `CMakeLists.txt`.

Bazel's `Runfiles::Create()` does not actually need a value for `argv0` in
order to find runfiles for the current `cc_binary`.
- Rename `runfiles.cc` to `runfiles_nobazel.cc`

The corresponding command-line option `sapi_isystem` will be ignored for
compatibility.

This makes `sapi_library()` more compatible with Bazel's native `cc_library()`
rule.

This should fix the build on Debian 10 with LLVM 11.
- Keep order of files to look up in `ls` invocation
- Use `--start-group`/`--end-group` linker options
- Drive-by: use `splitlines()` instead of manual `split("\n")[:-1]`

This change introduces an experimental `generator_version` attribute to the
`sapi_library()` rule. Version `1` will select the current interface
generator, which is based on libclang and Python. Setting the attribute to
version `2`, will select the newer interface generator written in C++ that
uses a full clang compiler frontend for parsing. Both emit equivalent header
output, differences in parsing and/or edge cases notwithstanding.
The default, as of now, is still the old version `1` generator.
Note: CMake allows to select the new interface generator globally by setting
`SAPI_ENABLE_GENERATOR`.
