qemu-iotests: Valgrind support

check -valgrind wraps all qemu-io calls with valgrind. This makes it a
bit easier to debug problems that occur somewhere deep in a test case.

qemu-iotests: add qcow2.py set-feature-bit command

This new command sets feature bits in the image file header:

qcow2.py set-feature-bit incompatible|compatible|autoclear &lt;bit&gt;

The bit number must be in the range [0, 64).

qemu-iotests: add 036 autoclear feature bit test

This new test validates the autoclear feature bit behavior. When QEMU
opens a qcow2v3 image file with an unknown autoclear feature bit the bit
should be cleared in the image file header.

qemu-iotests: fill streaming test image with data

The TestStreamStop test case is racy; if the job completes before we can
cancel it, it fails. If we remove the sleep the job will be canceled
before it has even started, and the test succeeds but it is also not...

qemu-iotests: start vms in qtest mode

This way, they will not execute any VM code at all. However, right now
the cancellation test is "relying" on being slowed down by TCG executing
BIOS code. So, change the timeouts.

qemu-iotests: Some backing file COW tests

Looks like we're still missing these very basic tests for backing file
handling.

qemu-iotests: COW with many AIO requests on the same cluster

This one is a bit more interesting. The COW operation isn't performed
completely synchronously, and therefore dependencies must be handled
correctly when multiple requests write to the same unallocated cluster....

qemu-iotests: mark 035 qcow2-only

The 035 parallel aio write test relies on knowledge of qcow2 metadata
layout to stress parallel L2 table accesses. This only works for qcow2
unless we add additional calculations for qed or other formats.

Mark this test as qcow2-only....

stream: do not copy unallocated sectors from the base

Unallocated sectors should really never be accessed by the guest,
so there's no need to copy them during the streaming process.
If they are read by the guest during streaming, guest-initiated
copy-on-read will copy them (we're in the base == NULL case, which...
