With SPC-4, the 0xE4 descriptor LU ID TYPE field should be ignored, and
the NUL bit is obsolete. Update the ValidTgtDescr accordingly.

ExtendedCopy.DescrLimits currently attempts to test Maximum Descriptor
List Length bounds checking by issuing a request with
(max_target_desc_count + 1 + max_segment_desc_count + 1) descriptors.
Maximum Descriptor List Length is a separately advertised field, that
may not be exceeded with the above logic, e.g. LIO advertises:
- Max Target Desc Count = 2
- Max Segment Desc Count = 1
- Max Desc List Len = 1024
Calculate the number of descriptors using the advertised Maximum
Descriptor List Length value, to explicitly test bounds checking.

We need to use iovectors for iSER to work as it requires that the vectors
are attached to the task before we queue the task.

- Various updates to the test utility
- Add transport abstraction
- Add support for iSER
- Add iscsi_discovery_sync()

Dispatch a write and subsequently reset the logical unit via iSCSI TMF.
This is based on the AbortTaskSimpleAsync test.

When run against an iSCSI target sd->sgio_dev may be NULL, so the
strncmp() coredumps.

As BLKSECTGET is so unreliable, skip using this to detect max transfer sizes
for any device path starting with "/dev/sg"
instead force the max to be 120k

Not all targets support cold/warm reset task management functions.
Abort these tests if the support is missing and the commands fail.

Let user specify iSER support by the protocol part of the URL.
I.e. support both
iser://127.0.0.1/iqn.ronnie.test/1
iscsi://127.0.0.1/iqn.ronnie.test/1?iser

This splits a transport into static driver specific functions for the common
iscsi commands. Optionally, a driver specific opaque memory is introduced
which is currently only used by iSER transport.
Last a lot of functions changed to static.

The iscsi cmdsn tests are noisy and generate a lot of [FAILURE]
warnings for things that are expected.
Fix this by do the plumbing to allow using a EXPECT_STATUS_TIMEOUT
for commands we expect will never be replied to and will thus time out.
