The bunch of pending changes. Sorry, it's quite big.

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
- Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
- Fixed possible dev_cmd_count underflow
- Minor iSCSI-SCST connection closing cleanups and fixes
- Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
- scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
- Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
- 64-bit cleanups
- Documented that iscsi-scst-adm is currently broken and explained why
- In user space Makefile's added possibility to specify external linker flags
- Minor performance optimizations
- Other minor cleanups

We can (somehow) get commands on an atio7 for which we've never had a PLOGI/PRLI.
How this happens, I don't know. Anyway, we stick a tentative entry in the PDB

stupidly, searching for the N-port handle by asking the chip. Sometimes it's not
there. In that case, we terminate the command.

Don't use both WWNs in the ICB block unless they're not NAA==2. This makes us
more consistent with QLogic driver setups and thus more likely to fit into the
same zoning setups.

If we're getting a PDB and it's for the Fabric Controller, force a login
to it (just in case it logged out underneath us). Return 'not logged in'
for the 24XX in case the 24XX specific login state isn't in the range of
PLOGI_DONE to LOGGED IN.

Don't do local loop scans if we have more than one channel (NP-IV) and we're
in a FL-port topology- we just end up poking ourselves usually.

Make sure we set loopstate in a couple of places we missed so that we
try and get it again.

Add in the RESET DEVICE and ABORT COMMAND functions for the 24XX cards
(finally).

Fix a longstanding bug where were passing the wrong (off by one) output
pointer to isp_handle_other_response.

Change isp_async...ISPASYNC_CHANGE_NOTIFY to have N-port handle, nlstate and
reason included as we get these for free with PDB Changed stuff for the
24XX card. Eventually we should be able to edit single local PDB entry
states instead of doing a full eval.

Put in the put of a 24XX Task Management Function IOCB. There is no get because
the firmware doesn't return it when done- instead a status iocb is done.

There is no "FAST POST" flag for the 24XX- this is a NOACK flag which means
that there is no interrupt if all goes well.

Fix spelling mistakes.

In isp_add_wwn_entry, ahem, don't allocate PDB entries out of the 'rexerved
for chip' area.

Put more comments in as to why we're terminating an exchange (and make them
all ISP_LOGTINFO).

Add, finally, the correct handling for a QIN_NOTIFY_ACK for a task management
function- this means we construct a ct7_entry_t to get the firmware to send
an FC Response IU for it. So, finally LUN RESETS and TARGET RESETS and
ABORT TASK will actually work and, more importantly, be seen to be working
by initiators.

Comment for r270:

1. A major botch for local loop handling - we were never getting past loopid zero
in isp_scan_loop. Bad doggie!

2. *Do* scan our loopid- this seems to allow us to find entities which are there
and have a N-port handle that is identical to ours. I have no idea how the QLogic
sorts this out. At least, this is how it seems to work for the 24XX in local loop
mode.

Don't deadlock with the HBA lock when performing a rescan ioctl. Also,
mark the loop state as if we'd just received a PDB event- that way
