#8797: semaphores for boost.thread

 Keywords: |
 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.
