* semaphore.h (sem_t): Is now an opaque pointer;
moved actual definition to implement.h.
* implement.h (sem_t_): Move here from semaphore.h;
was the definition of sem_t.
* semaphore.c: Wherever necessary, changed use of sem
from that of a pointer to a pointer-pointer; added
extra checks for a valid sem_t; NULL sem_t when
it is destroyed; added extra checks when creating
and destroying sem_t elements in the NEED_SEM
code branches; changed from using a pthread_mutex_t
((*sem)->mutex) to CRITICAL_SECTION ((*sem)->sem_lock_cs)
in NEED_SEM branches for access serialisation.
