fix issues seen with transfers being reused before they are finished
being used.
adapt locking to the modern world. some what inspired by if_smsc.c:
- add locks for softc, rx and tx
- add safe detach support
- safe detach vs mii lock requires 2 methods to lock the MII lock,
- check axen_dying and new axen_stopping more often
- consolidate checks to reduce the number of error paths that need
to release a resource
- move axen_watchdog() out of if_timer into the tick task to
prepare for MPSAFEification
TODO:
- remove spl usage
- enable mpsafe
special thanks to skrll and mlelstv for clearing up various
