Add crashdump support to the ips driver. It only works for the more modern

ServeRAID 4 - 7 models right now.  Support for older cards is possible, but
I don't have any hardware to experiment with.

Thanks to Jack Hammer at Adaptec for providing debugging hints.

Remove all of the spl() markers.

Lock the IPS driver and bring it out from under Giant. Also do some

significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
  us.
- remove all of the complicated bio deferral code.  bio's that can't be
  serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
  This simplifies a lot of code and significantly reduces the size of the
  command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
  call it indirectly.

Switch from using mutexes to using semaphores to protect against early

completion of synchronous commands.  Also switch to a per-array bioq as it
appears to improve performance.

Introduce d_version field in struct cdevsw, this must always be
