  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.
