Modifies several functions that are causing wrong behaviour. * semaphore.h: add missing restrict keyword. * sem_destroy(): check that nobody is waiting before destroying the object. * sem_timedwait(): simpify function logic and fix a bug when abstime > currtime, that passed ticks instead of ms to k_sem_take(). * sem_wait(): avoid unnecessary checks. * sem_init(): add pshared value assertion.
