8797	semaphores for boost.thread	timblechmann	viboes	"this patch adds support for semaphores to boost.thread.

in addition to an emulation with mutex/condition_variable/counter, it provides native implementations for win32, posix and dispatch semaphores. the reason for adding native implementations is performance: they perform much better than an emulation. on osx, i have seen a speedup of 80 in microbenchmarks with strong contention."
