Mega Update to the aac driver to support a whole new family of cards and
the modified interface that they use. Changes include:

- Register a different interrupt handler for the new interface. This one is
INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs.
- Add an event registration and callback mechanism for the ioctl and CAM
modules can know when a resource shortage clears. This condition was
previously fatal in CAM due to programming oversights.
- Fix locking to play better with newbus.
- Provide access methods for talking to cards with the NEWCOMM interface.
- Fix up the CAM module to be better suited for dealing with newer firmware
on the PERC Si/Di series that requires talking to plain SCSI via aac.
- Add a whole slew of new PCI Id's.

Thanks to Adaptec for providing an initial version of this work and for
answering countless questions about it. There are still some rough edges in
this, but it works well enough to commit and test for now.

Use time_uptime for timing commands instead of time_second. This is a bit
risky because the "current time" is supposed to be fed to the card during
initialization, and the current time is supposed to be put into each command
that is sent to the card. Hopefully either the card doesn't actually care
about the timestamps, or it doesn't care about the absolute values so long
and the relative values are consistent. Not an MFC candidate until more
thorough testing can be done.

If the timeout handler runs and notices that commands are timed out, check

Collapse sync fib locking into normal i/o locking. The former didn't

AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track
this down in RELENG_4.
