History
John Baldwin 1df95969b5 - 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.
