Various and sundry cleanups:
- Use curthread for calls to knlist_delete() and add a big comment
  explaining why as well as appropriate assertions.
- Use TAILQ_FOREACH and TAILQ_FOREACH_SAFE instead of handrolling them.
- Use fget() family of functions to lookup file objects instead of
  grovelling around in file descriptor tables.
- Destroy the aio_freeproc mutex if we are unloaded.

Tested on:	i386
