Clear persistent reservations before sending the first SCSI command to the
target to avoid that that command fails due to persistent reservations left
behind by a previous run of the test tool.
Avoid that a subsequent test fails if a test did not remove the persistent
reservations it obtained.
Make sure that clear_pr() returns -1 if clearing persistent reservations
fails.

This test registers PR key and then sends a PR-In read-keys request with
an ALLOCATION LENGTH value that forces response truncation. Ensure that
the ADDITIONAL LENGTH is *not* modified as a result of the truncation.
This test currently passes against TGT but fails against LIO (fix
pending).

Accepting an Allocation Length parameter allows us to test for
truncation of response data, as per SPC5r17 4.2.5.6:
The device server shall terminate transfers to the Data-In Buffer when
the number of bytes or blocks specified by the ALLOCATION LENGTH field
have been transferred or when all available data have been
transferred, whichever is less.
With this change, all existing prin_read_keys() callers continue to use
same ALLOCATION LENGTH value as earlier (16K).

When run against an iSCSI target sd->sgio_dev may be NULL, so the

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

Tests such as ProutPreempt presume each path they have is sending a
different initiator name. When using multipath this did not happen and
initiatorname1 was used on all paths.
Fix this by creating and initializing an array (currently size 2) of
initiator names and iterating it in step with each new path we make
(hopefully the compiler will complain if iscsi-test-cu ever supports
more than two multipaths and there isn't a corresponding initiatorname).

Dispatch a number of READ10 requests simultaneously, and await all
responses.
The iscsi-support test helper functions are currently all synchronous,
so this test mostly uses the bare libiscsi API. As new async tests are
added, we can make a more informed decision on which boilerplate code
can be split out.

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 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.

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.
