Axel Dörfler 9de969006b Added two experimental release_sem_etc() flags (both should stay, but they ...

may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
  (the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
  are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
