History
Bruce M Simpson 7f8851d0b9 Reintroduce and clean up locking in xl(4). 
- Eliminate the use of a recursive mutex.
 - Mark the driver as INTR_MPSAFE.
 - Split the default media choice code out into xl_choose_media() to
   avoid making poor assumptions about the state of the lock during attach.
 - The miibus upcall/downcall paths may still be racy.
   Change to commented-out locking assertions there for now.
 - Tested with nfsclient, routed, ssh, ntp, dhclient and quagga bgpd.
 - This needs SMP test coverage. I do not have such resources.

Tested on:	UP, !debug.mpsafenet && debug.mpsafenet
Hardware:	3C905B-TX (0x905510b7)
