Logd never deletes SerializedLogBuffer, so it seemed reasonable to
detach the deleter thread, however unit tests and fuzzers do delete
SerializedLogBuffer, so we must safely join the deleter thread in the
destructor.
This simplifies the deleter thread code and ensures that only one
deleter thread will be running at a time.
Test: fuzzing works

In order of severity:
1) Add a CHECK() that a pointer is not nullptr, where the analyzer
believes this is possible.
2) Add `final` appropriately to functions called from constructors.
3) Add missing cloexec flags.
4) Add missing `noexcept` and other subtle performance warnings
Test: build with clang-tidy

Initial commit for a SerializedLogBuffer. The intention here is for
the serialized data to be compressed (currently using zlib) to allow
for substantially longer logs in the same memory footprint.
Test: unit tests
