Normal applications want the current behaviour where we have the library
consume any/all of the UnitAttentions that the target may have queued on the
initial connection, but when we reconnect the session after a failure the
library will pass all the UAs back to the application to process.
Some applications, such as the test suite or really trivial applications
might not want to have to deal with handling of UAs and just "make it work".
Those applications can now request that upon any reconnection of the session
that libiscsi will automatically consume any and all UAs and hide them from
the application.

If the server closes the TCP connection before we call send() in
iscsi_write_to_socket() we will get SIGPIPE unless we pass this
argument to send.

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.

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

PREEMPT allows for the removal of registrations, and replacement of

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.

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.
