The current WRITE SAME (WS) 0 blocks test at LBA 0 isn't always correct
because if:
- The target's WSNZ bit set is 0
- The target's MAXIMUM WRITE SAME LENGTH (MWSL) is greater than 0
- We are issuing a WS with a NUMBER OF LOGICAL BLOCKS of 0
then whether the command should return success or failure depends on
whether the starting LBA is within MWSL blocks of the end of the LUN
(see http://www.t10.org/pipermail/t10/2016-May/017988.html for details).
Replace the vestigial code which tried to handle this (but no longer
worked since commit 8585e4509b ) and add
some additional MAXIMUM WRITE SAME LENGTH tests.

Based on the corresponding simple tests. Issue a WRITESAME request and
confirm that the data written matches the data read back.

There is technically no reason why a SSD with (assumingly with thin
provisioning) can not support SANITIZE/OVERWRITE instead or or in addition
to the more expected SANITIZE/BLOCK-ERASE so remove the warning for this.

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).

When libiscsi is built with clang several spurious
missing-field-initializers warnings like the following are reported:
test_async_write.c:61:45: error: missing field 'completed' initializer
[-Werror,-Wmissing-field-initializers]
struct tests_async_write_state state = { 0 };
These appear to be due to clang being overzealous in its checking
because the code is legal C (see
https://llvm.org/bugs/show_bug.cgi?id=21689 ) but it causes compilation
to be aborted. Workaround the problem by specifying a 0 or NULL for each
structure member.
Dispatch a number of Compare And Write requests simultaneously via
separate iSCSI sessions and await all responses.

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.

Move the scsi_free_scsi_task() call from receive_copy_results() to the
callers of this function to avoid that accessing the unmarshalled data
triggers a use-after-free.
