This change introduces a new non-reentrant mutex to WebRTC. It enables eventual migration to Abseil's mutex. The mutex types supportable by webrtc::Mutex are - absl::Mutex - CriticalSection (Windows only) - pthread_mutex (POSIX only) In addition to introducing the mutexes, the CL also changes PacketBuffer to use the new mutex instead of rtc::CriticalSection. The method of yielding from critical_section.cc was given a mini-cleanup and YieldCurrentThread() was added to rtc_base/synchronization/yield.h/cc. Additionally, google_benchmark benchmarks for the mutexes were added (test courtesy of danilchap@), and some results from a pthread/Abseil shootout were added showing Abseil has the advantage in higher contention.
