Instead of defining the macro _R_(), define __attribute__() as a macro for
compilers that do not support __attribute__(), namely Microsoft Visual
Studio.

Type 0x0A segment descriptors provide a 32-bit wide number-of-bytes
field, allowing for much larger copy offloads with a single segment
descriptor.

Declare dynamically allocated strings as 'char *' instead of 'const char *'.
Remove the discard_const() macro. Do not test whether or not a pointer is
NULL before calling free() because it is allowed to pass NULL to free().

All users have now been changed to overload via the iscsi_ctx transport
callback, so the dlsym based overloading can now be dropped.

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).

Since the data in the read buffer is not valid if READ10() failed,
only compare the data in the read buffer if READ10() succeeded.

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.

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.

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.

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.
