* 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.
