SYNOPSIS
    Signal(task, signals)
           A1    D0

    void Signal(struct task *,ulong);

FUNCTION
    This function signals a task with the given signals.  If the task
    is currently waiting for one or more of these signals, it will be
    made ready and a reschedule will occur. If the task is not waiting
    for any of these signals, the signals will be posted to the task
    for possible later use. A signal may be sent to a task regardless
    of whether its running, ready, or waiting.

    This function is considered "low level".  Its main purpose is to
    support multiple higher level functions like putmsg.

    This function is safe to call from interrupts.

INPUT
    task - the task to be signalled
