Add some hooks into the driver to attach, detach and record EDMA descriptor
events.

This is primarily for the TX EDMA and TX EDMA completion. I haven't yet
tied it into the EDMA RX path or the legacy TX/RX path.

Things that I don't quite like:

* Make the pointer type 'void' in ath_softc and have if_ath_alq*()
  return a malloc'ed buffer.  That would remove the need to include
  if_ath_alq.h in if_athvar.h.
* The sysctl setup needs to be cleaned up.
