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.

Loss notifications may either be sent immediately, or wait until another
RTCP feedback message is sent.

For binary size reasons; they emit too many instructions at each call
site.
I decided to not point out replacements for them, since rtc::join has
only one caller, and rtc::split isn't the only option for splitting
strings. And both of them have APIs that can cause the creation of
needless temporary strings.

std::is_trivially_* is not available on certain old STL
implementations. Using absl implementation will allow
maximized compatibility.
