If a previous run of the test tool had been interrupted one or
more persistent reservation keys can still be registered. This
can cause tests in the new run to fail. Avoid this by clearing
these keys before running any tests. Do this only if --dataloss
has been specified.

Avoid that running the regression tests against a LUN with size zero triggers
the following assertion failure:

test_iscsi_tur_until_good() dispatches TUR requests until the target has
cleared all UAs for the given sd, or the maximum number of retries is
reached.
This helper function is useful for any test that needs to deal with UAs
(e.g. PRs), so should be moved out into common code.

Issue a Persistent Reservation Out PREEMPT request, with keys and type
provided.
PREEMPT allows for the removal of registrations, and replacement of
reservations.

A number of existing tests create a secondary iSCSI session by logging
into the target specified in the base sd during the test.
With multipath sessions now connected during iscsi-test-cu startup
(when launched with multiple URIs), secondary sessions can be
provided via multipath when available, rather than reconnecting.
This change adds a helper that conditionally returns the secondary
multipath device if available, or falls back to creating a new session
via the base sd target details.

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.

From Alexander Motin <mav@freebsd.org>
Treat BlockLimits VPD atomic granulatity/alignment reported as 0
(no restrictions) as == 1 (also means no restriction).
Both 0 and 1 mean that there is no restriction on alignment or
granularity but with the difference being that the second value can
be used to increment to the next valid LBA.
