driver-induced errors, instead be better about propagating error status
upwards. Add more error definitions, courtesy of the linux driver. Fix
a command leak in the ioctl handler. Re-arrange some of the command handlers
to localize error handling.

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.

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.

them working (cache, automatic rebuild and hotswap) the FFDC
info (First Failure Data Capture) on the adapter must be
initialised.
Logical drives in critical/degraded states weren't added to
the drive list. FreeBSD was not able to see a degraded array
after a reboot. Degraded drives are now also added to the drivelist
and the state of the logical drive is given at boottime.
The adapter type is detected from informations in nvram page 5
and displayed at boottime.
Change IPS_OS_FREEBSD definition from 10 to 8 according to IBM
specs.

- enable the ability to set the 'disable' hint for the driver to keep it
from attaching. i.e. 'hw.ips.0.disable=1' will prevent the driver from
attaching.
- Only detach if attach suceeded.

Jeffreys and Adaptec. I've updated it to work with 5.x and fixed a
few bugs.
