We already have an extensive mirror test (041) which does cover
cancelling a mirror job, especially after it has emitted the READY
event. However, it does not check what exact events are emitted after
block-job-cancel is executed. More importantly, it does not use
throttling to ensure that it covers the case of block-job-cancel before
READY.
It would be possible to add this case to 041, but considering it is
already our largest test file, it makes sense to create a new file for
these cases.

Test
- start two vms (vm_a, vm_b)
- in a
- do writes from set A
- do writes from set B
- fix bitmap sha256
- clear bitmap
- do writes from set A
- start migration
- than, in b
- wait vm start (postcopy should start)
- do writes from set B
- check bitmap sha256
The test should verify postcopy migration and then merging with delta
(changes in target, during postcopy process).
Reduce supported cache modes to only 'none', because with cache on time
from source.STOP to target.RESUME is unpredictable and we can fail with
timout while waiting for target.RESUME.

This test case adds an NBD server export and then invokes

When originally written, test 177 explicitly took care to run
with compat=0.10. Then I botched my own test in commit
81c219ac and f0a9c18f, by adding additional actions that require
v3 images. Split out the new code into a new v3-only test, 204,
and revert 177 back to its original state other than a new comment.

After committing the qcow2 image contents into the base image, qemu-img
will call bdrv_make_empty to drop the payload in the layered image.
When this is done for qcow2 images, it blows away the LUKS encryption
header, making the resulting image unusable. There are two codepaths
for emptying a qcow2 image, and the second (slower) codepath leaves
the LUKS header intact, so force use of that codepath.

Add a test for qcow2 copy-on-read behavior, including exposure
for the just-fixed bugs.
The copy-on-read behavior is always to a qcow2 image, but the
test is careful to allow running with most image protocol/format
combos as the backing file being copied from (luks being the
exception, as it is harder to pass the right secret to all the
right places). In fact, for './check nbd', this appears to be
the first time we've had a qcow2 image wrapping NBD, requiring
an additional line in _filter_img_create to match the similar
line in _filter_img_info.
Invoking blkdebug to prove we don't write too much took some
effort to get working; and it requires that $TEST_WRAP (based
on $TEST_DIR) not be subject to word splitting. We may decide
later to have the entire iotests suite use relative rather than
absolute names, to avoid problems inherited by the absolute
name of $PWD or $TEST_DIR, at which point the sanity check in
this commit could be simplified.
This test requires at least 2G of consecutive memory to succeed;
as such, it is prone to spurious failures, particularly on
32-bit machines under load. This situation is detected and
triggers an early exit to skip the test, rather than a failure.
To manually provoke this setup on a beefier machine, I used:
$ (ulimit -S -v 1000000; ./check -qcow2 197)

No tests were covering write zeroes with unmap. Additionally,
I needed to prove that my previous patches for correct status
reporting and write zeroes optimizations actually had an impact.
The test works for cluster_size between 8k and 2M (for smaller
sizes, it fails because our allocation patterns are not contiguous
with small clusters - in part, the largest consecutive allocation
we tend to get is often bounded by the size covered by one L2
table).
Note that testing for zero clusters is tricky: 'qemu-io map'
reports whether data comes from the current layer of the image
(useful for sniffing out which regions of the file have
QCOW_OFLAG_ZERO) - but doesn't show which clusters have mappings;
while 'qemu-img map' sees "zero":true for both unallocated and
zero clusters for any qcow2 with no backing layer (so less useful
at detecting true zero clusters), but reliably shows mappings.
So we have to rely on both queries side-by-side at each point of
the test.

Use blkdebug's new geometry constraints to emulate setups that
have needed past regression fixes: write zeroes asserting
when running through a loopback block device with max-transfer
smaller than cluster size, and discard rounding away portions
of requests not aligned to preferred boundaries. Also, add
coverage that the block layer is honoring max transfer limits.
For now, a single iotest performs all actions, with the idea
that we can add future blkdebug constraint test cases in the
same file; but it can be split into multiple iotests if we find
reason to run one portion of the test in more setups than what
are possible in the other.
For reference, the final portion of the test (checking whether
discard passes as much as possible to the lowest layers of the
stack) works as follows:
qemu-io: discard 30M at 80000001, passed to blkdebug
blkdebug: discard 511 bytes at 80000001, -ENOTSUP (smaller than
blkdebug's 512 align)
blkdebug: discard 14371328 bytes at 80000512, passed to qcow2
qcow2: discard 739840 bytes at 80000512, -ENOTSUP (smaller than
qcow2's 1M align)
qcow2: discard 13M bytes at 77M, succeeds
blkdebug: discard 15M bytes at 90M, passed to qcow2
qcow2: discard 15M bytes at 90M, succeeds
blkdebug: discard 1356800 bytes at 105M, passed to qcow2
qcow2: discard 1M at 105M, succeeds
qcow2: discard 308224 bytes at 106M, -ENOTSUP (smaller than qcow2's
1M align)

qcow2: Don't strand clusters near 2G intervals during commit
extended the 097 test case so that it did two passes, once
with an internal snapshot, once without.
qcow (v1) does not support internal snapshots, so this change
broke test 097 when run against qcow.
This splits 097 in two, creating a new 176 that tests the
internal snapshot codepath, effectively putting 097 back
to its content before the above commit.
