migration: Always set DEVICE state

migration: Always set DEVICE state
DEVICE state was introduced back in 2017:
https://lore.kernel.org/qemu-devel/20171020090556.18631-1-dgilbert@redhat.com/
Quote from Dave's cover letter, when the pre-switchover phase was enabled, the state transition looks like this:
The precopy flow is: active->pre-switchover->device->completed
The postcopy flow is: active->pre-switchover->postcopy-active->completed
To supplement above, when the cap is not enabled:
The precopy flow is: active->completed
The postcopy flow is: active->postcopy-active->completed
It works for us, though we have some code just to special case these state transitions, so the DEVICE state currently is special only to precopy, and only conditionally.
I had a quick discussion with Libvirt developers, it turns out that this may not be necessary. IOW, it seems okay we can have DEVICE state to be generic, so that we don't have over-complicated state machines. It not only helps align all the migration state machine, help cleanup the code path especially on pre-switchover handling (see the patch itself), another side benefit is we can unconditionally have a specific state to mark the switchover phase, which might be helpful for debugging too.
This patch makes the DEVICE state to be present always, marking that source QEMU is switching over. Then the state machine will be always as simple as:
active-> [pre-switchover->] -> device -> [postcopy-active->] -> complete
After the change, no matter whether pre-switchover or postcopy is enabled or not, we always have DEVICE state showing the switchover phase. When pre-switchover enabled, we'll have an extra stage before that. When postcopy is enabled, we'll have an extra stage after that.
A few qtests need touch up in QEMU tree for this change:
- A few iotest outputs (194, 203, 234, 262, 280) - Teach libqos's migrate() on "device" state

qcow2: introduce compression type feature
The patch adds some preparation parts for incompatible compression type feature to qcow2 allowing the use different compression methods for image clusters (de)compressing.
It is implied that the compression type is set on the image creation and can be changed only later by image conversion, thus compression type defines the only compression algorithm used for the image, and thus, for all image clusters.
The goal of the feature is to add support of other compression methods to qcow2. For example, ZSTD which is more effective on compression than ZLIB.
The default compression is ZLIB. Images created with ZLIB compression type are backward compatible with older qemu versions.
Adding of the compression type breaks a number of tests because now the compression type is reported on image creation and there are some changes in the qcow2 header in size and offsets.
The tests are fixed in the following ways: * filter out compression_type for many tests * fix header size, feature table size and backing file offset affected tests: 031, 036, 061, 080 header_size +=8: 1 byte compression type 7 bytes padding feature_table += 48: incompatible feature compression type backing_file_offset += 56 (8 + 48 -> header_change + feature_table_change) * add "compression type" for test output matching when it isn't filtered affected tests: 049, 060, 061, 065, 082, 085, 144, 182, 185, 198, 206, 242, 255, 274, 280

iotests: Test external snapshot with VM state
This tests creating an external snapshot with VM state (which results in an active overlay over an inactive backing file, which is also the root node of an inactive BlockBackend), re-activating the images and performing some operations to test that the re-activation worked as intended.
