MFC: Sync up with locking changes in HEAD:
- Add locked variants of nve_start(), nve_init(), and nve_ifmedia_upd().
- Use callout_* to manage callouts rather than timeout(9).
- Mark interrupt handler MPSAFE (IFF_NEEDGIANT was already clear).
- Lock the driver lock in driver entry points such as the interrupt
  handler, if_start, and if_init rather than locking the driver mutex
  in the various work functions called by the binary blob.
- Use IFQ_DRV_IS_EMPTY() macro rather than doing it by hand.
- Fix locking in detach.
- Remove some unused fields from the softc.
- Don't make the driver lock recursive, it shouldn't be recursively
  acquired anywhere in the driver now.
- Axe the spin mutex used for the nve_oslock*() routines.  The driver lock
  already provides sufficient synchronization.
- Don't mess around with IFF_UP when the link state changes.  IFF_UP is
  an administrative flag, not a link status indicator.
