qcow2: Fix v3 snapshot table entry compliancy

qcow2: Repair snapshot table with too many entries
The user cannot choose which snapshots are removed. This is fine
because we have chosen the maximum snapshot table size to be so large
(65536 entries) that it cannot be reasonably reached. If the snapshot
table exceeds this size, the image has probably been corrupted in some
way; in this case, it is most important to just make the image usable
such that the user can copy off at least the active layer.
(Also note that the snapshots will be removed only with "-r all", so a
plain "check" or "check -r leaks" will not delete any data.)

qcow2_check_read_snapshot_table() can perform consistency checks, but it
cannot fix everything. Specifically, it cannot allocate new clusters,
because that should wait until the refcount structures are known to be
consistent (i.e., after qcow2_check_refcounts()). Thus, it cannot call
qcow2_write_snapshots().

qcow2_check_refcounts().

iotests: Introduce $SOCK_DIR
Unix sockets generally have a maximum path length. Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.
Circumvent this by adding a new scratch directory specifically for
Unix socket files. It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.
(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)
Use mkdir -p to create the directory (because it seems right), and do
the same for $TEST_DIR (because there is no reason for that to be
created in any different way).

block/mirror: support unaligned write in active mirror
Prior
9adc1cb49af8d do_sync_target_write had a bug: it reset aligned-up
region in the dirty bitmap, which means that we may not copy some bytes
and assume them copied, which actually leads to producing corrupted
target.
So
9adc1cb49af8d forced dirty bitmap granularity to be
request_alignment for mirror-top filter, so we are not working with
unaligned requests. However forcing large alignment obviously decreases
performance of unaligned requests.
This commit provides another solution for the problem: if unaligned
padding is already dirty, we can safely ignore it, as
1. It's dirty, it will be copied by mirror_iteration anyway
2. It's dirty, so skipping it now we don't increase dirtiness of the
bitmap and therefore don't damage "synchronicity" of the
write-blocking mirror.
If unaligned padding is not dirty, we just write it, no reason to touch
dirty bitmap if we succeed (on failure we'll set the whole region
ofcourse, but we loss "synchronicity" on failure anyway).
Note: we need to disable dirty_bitmap, otherwise we will not be able to
see in do_sync_target_write bitmap state before current operation. We
may of course check dirty bitmap before the operation in
bdrv_mirror_top_do_write and remember it, but we don't need active
dirty bitmap for write-blocking mirror anyway.
New code-path is unused until the following commit reverts
9adc1cb49af8d.

case_notrun() does not actually skip the current test case. It just
adds a "notrun" note and then returns to the caller, who manually has to
skip the test. Generally, skipping a test case is as simple as
returning from the current function, but not always: For example, this
model does not allow skipping tests already in the setUp() function.
Thus, add a QMPTestCase.case_skip() function that invokes case_notrun()
and then self.skipTest(). To make this work, we need to filter the
information on how many test cases were skipped from the unittest
output.

tests/ssh_linux_malta: Fix 64-bit target tests
Commit
9090d3332cdcc added tests for specific to the 32-bit
machines, which inadvertently make the 64-bit tests failing.
Now than we have this information available in the CPU_INFO
array, use it to have the 64-bit tests back.

qcow2: Fix corruption bug in qcow2_detect_metadata_preallocation()
qcow2_detect_metadata_preallocation() calls qcow2_get_refcount() which
requires s->lock to be taken to protect its accesses to the refcount
table and refcount blocks. However, nothing in this code path actually
took the lock. This could cause the same cache entry to be used by two
requests at the same time, for different tables at different offsets,
resulting in image corruption.
As it would be preferable to base the detection on consistent data (even
though it's just heuristics), let's take the lock not only around the
qcow2_get_refcount() calls, but around the whole function.
This patch takes the lock in qcow2_co_block_status() earlier and asserts
in qcow2_detect_metadata_preallocation() that we hold the lock.
