structure cleanups.

This code does not imply that SBus cards work yet. They hang for me.
But I can't netboot the latest snapshot on my ultra1e, and things
hang at bus_setup_intr time.

Since I'm offline for a while, I thought I'd toss this in in case somebody
else who has a bit better luck wants to fart around with it. Please try
and wait until I get back to check things in.

Go back to *not* fully evaluating loop/fabric state if our role
is ISP_ROLE_NONE.

lun address modifier of sorts. Only an HP XP-512 seems to have cared.

Fix a few misplaced pointers for the new fabric goop, which has been
demonstrated to work on newer Brocades and McData switches now.
Put in commented out code which would run GFF_ID if the QLogic f/w
allowed it.

Don't whine about not being able to find a handle for a command if it
was a command aborted (by us).

version worked fine, but Linux/Sparc && FreeBSD/Sparc choked.

Grumble. I've seen better documented architectures out of Redmond.

Redo fabric evaluation to not use GET ALL NEXT (GA_NXT). Switches seem
to be trying to wriggle out of supporting this well. Instead, use
GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the
port and node wwn. This should make working on fabrics a bit cleaner and
more stable.

This also caused some cleanup of SNS subcommand canonicalization so that
we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT,
print out the reason and explanation codes.

We'll keep the old GA_NXT method around if people want to uncomment a
controlling definition in ispvar.h.

This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument
and to have the caller explicitly say that a device is at the end of the
fabric list.
