Make oltr(4) MPSAFE:
- Add a mutex to the softc and use it to protect the softc and device
  hardware.
- Setup interrupt handler after interface attach.
- Retire 'unit' from softc and use if_printf() instead.
- Don't frob IFF_UP in the driver.
- Use callout_() rather than timeout() and untimeout().
