If scsi_cdb_persistent_reserve_out() succeeds a call to
scsi_free_scsi_task() won't free any memory allocated with scsi_malloc()
in this function because the memset() call in this function overwrites
the task->mem pointer. Move the memset() call up such that it doesn't
clear task->mem. This makes it possible for the caller of this function
to free the memory allocated by this function by calling
scsi_free_scsi_task(). Merge the error handling code such that the code
for freeing memory only occurs once.

Several cleanup paths can be simplified if it is allowed to pass a
NULL pointer to scsi_free_scsi_task(). Hence modify this function
such that it returns immediately if passed a NULL task pointer.

- Add manpages for iscsi-ls/iscsi-inq and iscsi-swp
- Many new tests and updates to the testsuite.
- Fix memory leak in iscsi_reconnect
- Fixes to the persistent reservation tests
- AROS support
- Fix/restore windows support
- Switch to libgcrypt for the MD5 support.

Linux distributions like openSUSE 12.3 include CUnit version 2.
Apparently libiscsi uses some CUnit version 1 data structures that
have been modified in CUnit version 2. This causes the libiscsi
build to fail against CUnit version 2. Fix this by detecting the
CUnit version during the configure step.

clang defaults to c99 so remove inline statements
(http://clang.llvm.org/compatibility.html#inline ) on functions shared
across different translation units.
clang's linker doesn't like major numbers over 255 so change how SOREL
is generated in Makefile.am.
Previously COMPAREANDWRITE was only sending verify instance data which
can cause targets to generate COMMAND ABORTED/NOT ENOUGH UNSOLICITED
DATA errors due to the buffer being obviously too small to contain
verify AND write instance data.
The buffer size check has been modified and compareandwrite tests
updated to pass a larger buffer with interesting write instance data.
