- Use the correct DMA tag/map pair for synchronize the FC scratch area.
- Allocate coherent DMA memory for the request/response queue area and

These changes allow isp(4) to work properly on sparc64 with usage of the
IOMMU streaming buffers enabled.

Be more specific about which CDB length we're going to use. Not really a likely
bug but we might as well be clearer.

Various minor and not so minor fixes suggested by Coverity.
In at least one case, it's amazing that target mode worked at all.

Clean up some printing stuff so that we can have a bit finer control
on debug output. Add a new platform function requirement to allow
for printing based upon the ITL nexus instead of the isp unit plus
channel, target and lun. This allows some printouts and error messages
from the core code to appear in the same format as the platform's
subsystem (in FreeBSD's case, CAM path).

MFC of 204397: fix problems with fast posting handles

Revamp the pieces of some of the stuff I forgot to do when shifting to
32 bit handles. The RIO (reduced interrupt operation) and fast posting
for the parallel SCSI cards were all 16 bit handles. Furthermore,
target mode parallel SCSI only can have 16 bit handles.

Use part of a supplied patch to switch over to using 32 bit handles.
Be a bit more conservative here and only do this for parallel SCSI
for the 12160 (Ultra3) cards. There were a lot of marginal Ultra2
cards, and, frankly, few are findable now for testing.

Fix the target handle routine to only do 16 bit handles for parallel
SCSI cards. This is okay because the upper sixteen bits of the new
32 bit handles is a sequence number to help protect against duplicate
completions. This would be very unlikely to happen with parallel
SCSI target mode, and wasn't present before, so we're no worse off
than we used to be.

While we're at it, finally split the async mailbox completion handlers
into FC and parallel SCSI functions. This makes it much cleaner and
easier to figure out what is or isn't a legal async mailbox completion
code for different card classes.

Redo how commands handles are created and managed and implement sequence
numbers and handle types in rational way. This will better protect from
(unwittingly) dealing with stale handles/commands.

Fix the watchdog timeout code to better protect itself from mistakes.

If we run an abort on a putatively timed out command, the command
may in fact get completed, so check to make sure the command we're
timing it out is still around. If the abort succeeds, btw, the command
should get returned via a different path.

Amazingly we've been freeing a handle and using that which it refers to
for years. Bad!
