Sync with HEAD. Revisions merged:

  - rev. 1.76. Removed FreeBSD 4.x code.
  - rev. 1.77, 1.79. Together with rev. 1.71 (already merged) this
    fixes problems when some code is executed in driver when
    em_process_receive_interrupts() drops lock. This can occur
    at runtime, when polling(4) mode is changed to interrupt driver
    or vise versa, but more likely this can happen when administrator
    issues some ifconfig commands.
  - rev. 1.78. In em_process_receive_interrupts(), call bus_dmamap_sync()
    for the descriptors set each time we modify one descriptor, instead
    of doing it only at the function exit.
  - rev. 1.80. Loop in em_intr() until interrupt cause register is clear,
    don't mask overrun interrupt.
  - rev. 1.81. Several locking and other fixes.

See particular revision logs for more detailed information.
