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.

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.

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`.

This fixes the main issue (#118) with stack traces on Fedora, which uses a
`/lib64` and `/usr/lib64`.

The feature is pure optimization, but it requires
additional syscalls.

munmap is widely used by sanitizer, but it
probably works for Asan/Msan because it's enabled
by unrelated Allow* call.
Move mprotect to shared part as well. It will be
needed for compress_stack_depot.
