NAME
    ReleaseSemaphore -- make signal semaphore available to others

SYNOPSIS
    ReleaseSemaphore(signalSemaphore)
                     A0

    void ReleaseSemaphore(struct SignalSemaphore *);

FUNCTION
    ReleaseSemaphore() is the inverse of ObtainSemaphore(). It makes
    the semaphore lockable to other users.  If tasks are waiting for
    the semaphore and this this task is done with the semaphore then
    the next waiting task is signalled.

    Each ObtainSemaphore() call must be balanced by exactly one
    ReleaseSemaphore() call.  This is because there is a nesting count
    maintained in the semaphore of the number of times that the current
    task has locked the semaphore. The semaphore is not released to
    other tasks until the number of releases matches the number of
    obtains.

    Needless to say, havoc breaks out if the task releases more times
    than it has obtained.

INPUT
   signalSemaphore -- an initialized signal semaphore structure

NOTE
    This call is guaranteed to preserve all registers.
