We can not test that UNMAP will actually unmap anything even if
it returned status GOOD from the device.
Devices are allowed to "do nothing and return status GOOD" whenever they
want to.

Add a test for unmapping a single range of blocks and that
get_lba_status returns correct data.
Test unmapping a single block at offsets 0-255
Test unmapping 1-255 blocks at offset 0 and verify that
get_lba_status at LBA 0 returns a descriptor of 1-255 blocks.
get_lba_status at the last block of the unmapped range returns
a descriptor for a single block.

Since writing headers and payload in a single iov has never been
implementend and after thinking about it several times seems to
be very hairy I would like to revert this change since
the original implementation is in O(1) while the changed one
is in O(n). This results in a complexity of O(n^2) instead of
O(n) for the whole send operation.
This reverts commit 06eab264f6.
if the socket is corked we otherwise set POLLOUT and then
do not sent. Depending on the event loop implementation this
can result in a busy wait.

Dell Equallogic sans report an invalid LBA offset in the descriptor when
using 4k LUNs. Check the descriptor for consistency with the request.

The outqueue_current PDU might also be in waitpdu if it does not have
ISCSI_PDU_DELETE_WHEN_SENT. outqueue_current is freed after the
waitpdu list (for reconnect or defer_reconnect), or sometimes not
considered at all (for cancel), and this can cause a dangling pointer.
Keep outqueue_current up to date when a PDU is freed. A bit hacky,
but it avoids touching code all over the place.

if the rejected packet is a NOP-Out it is legal
that it has no callback. In this case we end

1.10 and 1.11 both introduced incompatible changes to the
libiscsi ABI. Please do not do that, and feel free to Cc
me on any patch that touches include/. In the meanwhile,
bump the soname of the library. I suggest releasing 1.11.1
with this change for distros.

- writesame10_unmap_until_end, writesame16_unmap, writesame16_unmap_until_end were doing an CU_ASSERT *PER-BYTE* in the verification phase,
which was very CPU-intensive. This change uses memcmp on a whole block which finishes much quicker.
This patch uses appropriate format string specifiers for uint64_t
types taken from inttypes.h, instead of using %lu, because %lu is
wrong at least on 32bit architecture.
Also, cast size_t expressions to unsigned long, again, because on at least
32bit architectures, size_t is int, not long.
