  Modified files:
    sys/kern             kern_synch.c 
  Log:
  - Lock CURSIG() with the proc lock to close the signal race with psignal.
  - Grab Giant around ktrace points.
  - Clean up KTR_PROC tracepoints to not display the value of
    sched_lock.mtx_lock as it isn't really needed anymore and just obfuscates
    the messages.
  - Add a few if conditions to replace gotos.
  - Ensure that every msleep KTR event ends up with a matching msleep resume
    KTR event (this was broken when we didn't do a mi_switch()).
  - Only note via ktrace that we resumed from a switch once rather than twice
    in several places in msleep().
  - Remove spl's rom asleep and await as the proc lock and sched_lock provide
    all the needed locking.
  - In mawait() add in a needed ktrace point for noting that we are about to
    switch out.
