Check that a Persistent Reserve Out CLEAR request:
- clears an existing reservation
- clears existing registration keys
- bumps the PRgeneration number

Confirm that data is consistent across paths when using the atomic
COMPARE AND WRITE operation.
This should be extended in future to issue the requests simultaneously
across both paths, in an attempt to trigger a read/write race.

This test issues a logical unit reset iSCSI TMF request, and then
confirms that all paths report a subsequent unit attention condition.

Write data to device via one path, then read back using a different
path. Confirm that data is correct.

Connect to each iSCSI URL provided, and confirm that they all correspond
to the same multipathed logical unit by using the previously added
mpath_check_matching_ids() helper.

this variable was introduced for iscsi-test-cu only. This patch
makes it a generic environment variable that can be set per context.

Disable memory caching in libiscsi if the environment variable
LIBISCSI_CACHE_ALLOCATIONS has been set to zero. This makes
Valgrind reports more meaningful.

We support SG_IO on various block devices, including but not limited to:
SCSI disks, CDROMs and tapes, virtio-blk and nvmve.
Instead of checking a filename prefix just treat anything that isn't
an iscsi:// url as a device node. The ioctl checks after open will weed
out devices (or files) that don't support SG_IO.

Remove the flags tests for READ* and replace them with a test for the DPO
and FUA bits.
IF the device claims DPOFUA support in modesense then the READ* CDBs
MUST allow these two flags. IF the device does NOT claim DPOFUA then any
READ* CDB with these flags must fail with invalod field in cdb.

Add a test for unmapping a single range of blocks and that
get_lba_status returns correct data.
Test unmapping a single block at offsets 0-255
Test unmapping 1-255 blocks at offset 0 and verify that
get_lba_status at LBA 0 returns a descriptor of 1-255 blocks.
get_lba_status at the last block of the unmapped range returns
a descriptor for a single block.

Allow specifying a --test <file> in which case the tests listed in the file
will be executed.
This makes it easier than having to specify a potentially huge number
of tests on the command line.
Free read_write_buf and task after each test. Free iscsi2 after
each PGR test when using CUnit version 2. Note: CUnit version 1
doesn't support test setup and teardown functions.

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.
