Final update to current version of head in preparation for reintegration.

On sparc64 obtain the initiator ID from the Open Firmware device tree
in order to match what the PROM built-in driver uses.

This is an MFC of 205236

Put gone device timer into a structure tag that can hold more than 32 seconds. Oops.

Untangle some of the confusion about what role means when it's in the FCPARAM/SDPARAM
or isp_fc/isp_spi structures. This fixed a problem about seeing targets appear if you've
turned off autologin and find them, or rather don't, via camcontrol rescan.

MFC of 204397: fix problems with fast posting handles

MFC of 204384: Fix misallocation error in target mode

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.

Add 8Gb support (isp_2500). Fix a fair number of configuration and
firmware loading bugs.

Target mode support has received some serious attention to make it
more usable and stable.

Some backward compatible additions to CAM have been made that make
target mode async events easier to deal with have also been put
into place.

Further refinement and better support for NP-IV (N-port Virtualization)
is now in place.

Code for release prior to RELENG_7 has been stripped away for code clarity.

Temporarily desupport simultaneous target and initiator mode.

When the linux port changes were imported which split the
target command list to be separate from the initiator command
list and the handle format changed to encode a type in the handle
the implications to the function isp_handle_index (which only
the NetBSD/OpenBSD/FreeBSD ports use) were overlooked.

The fault is twofold: first, the index into the DMA maps
in isp_pci is wrong because a target command handle with
the type bit left in place caused a bad index (and panic)
into dma map. Secondly, the assumption of the array
of DMA maps in either PCS or SBUS attachment structures is
that there is a linear mapping between handle index and
DMA map index. This can no longer be true if there are
overlapping index spaces for initiator mode and target
mode commands.

These changes bandaid around the problem by forcing us
to not have simultaneous dual roles and doing the appropriate
masking to make sure things are indexed correctly. A longer
term fix is being devloped.
