scst_local: Change max_lun into SCST_MAX_LUN (16383)
Today SCST does not support LUN numbers >= 16384. Additionally,
there is a bug in older Linux initiator systems that prevents
proper handling of LUN numbers >= 2**32. See also Hannes Reinecke,

Hush Coverity warning of scst_ws_push_single_write() uninitialized pointer
Coverity warns that sgv may be used uninitialized. The warning
applies to WRITE SAME commands with LBDATA == PBDATA == 0 (replicate
a single block of user data into the specified LBA range).
The warning appears to be spurious - when LBDATA == PBDATA == 0,
scst_ws_write_cmd_finished() will not use the uninitialized value
saved by scst_ws_push_single_write().
Move initialization of sgv earlier in the function to quiesce the warning.

scst_user, rt: Wake command processing thread when needed
In a fully-preemptible realtime kernel (CONFIG_PREEMPT_RT_FULL=y),
SCSI commands from an initiator time out because the userland target
application is never woken to process them.
This is because in a fully-preemptible realtime kernel, soft-IRQ
(tasklet) execution always occurs in a ksoftirqd thread and
preempt_count is not manipulated on soft-IRQ processing entry/exit.
This makes in_interrupt() useless for determining whether soft-IRQ
processing is occurring; instead, in_serving_softirq() should be
used for that purpose.

Fix spurious BUG when parse_type != SCST_USER_PARSE_STANDARD
Changeset 4224 introduced EXTRACHECKS for valid lba/data_len and state
at the end of the parsing phase of command processing.
However, the checks do not account for deferral of parsing to userland,
as occurs when SCST_USER_PARSE_CALL or SCST_USER_PARSE_EXCEPTION are specified.
In such cases the checks report errors on commands that userland has not yet
had an opportunity to parse.
NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity.
The rework is not exactly equivalent to the original code, but does
conform to the comments describing the original code.
Specifically, the original code would not trap an illegal command state
unless there was also an illegal lba or data_len.

Makefiles: calculate KVER properly
When deriving the kernel version (KVER) from KDIR, the file
$(KDIR)/include/config/kernel.release should be preferred over
'make kernelversion'.
For example, the Ubuntu 3.2.0-23-generic kernel has a kernel.release
file containing '3.2.0-23-generic', but 'make kernelversion' returns
3.2.14. Since the modules are stored under /lib/modules/3.2.0-23-generic,
the value in kernel.release is the correct one to use.
Also:
- Evaluate KVER only once
- All depmod commands must include KVER

scst, qla2x00t: Prevent inappropriate sleeping with a real-time kernel
With a realtime kernel with full preemption (CONFIG_PREEMPT_RT_FULL),
spinlocks can sleep, interrupt handlers run in thread context, and
the standard local_irq functions manipulate preemptibility, not HW
interruptibility. Under these conditions, most calls to local_irq
functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch
defines _nort versions of local_irq functions that compile away
under CONFIG_PREEMPT_RT_FULL and compile to their "normal"
equivalents otherwise.
Define _nort equivalents to support compilation against both
"normal" and RT-patched kernels, and use the _nort local_irq
functons in cases where spinlocks are taken within a
local_irq_save() or local_irq_disable() block. Without these
changes, runtime warnings about "sleeping function called from
invalid context" occur.
