[SCSI] 2.6 aacraid: Variable FIB size (updated patch)

Browse Source 
New code from the Adaptec driver.  Performance enhancement for newer
adapters.  I hope that this isn't too big for a single patch.  I believe
that other than the few small cleanups mentioned, that the changes are
all related.

- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
  requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup

Passes sparse check.
I have tested it on x86 and ppc64 machines.
