v2:
* rework compression type setting [Vladimir]
* squash iotest changes to the compression type introduction patch [Vladimir,
Eric]
* fix zstd availability checking in zstd iotest [Vladimir]
* remove unnecessry casting [Eric]
* remove rudundant checks [Eric]
* fix compressed cluster layout in qcow2 spec [Vladimir]
* fix wording [Eric, Vladimir]
* fix compression type filtering in iotests [Eric]
v1:
the initial series
---
zstd comression method is faster than the only available zlib.
The series adds zstd to the methods available for clusters compression.
The implementation is done with respect to the recently added compression
type additional header to the qcow2 specification.
Denis Plotnikov (4):
qcow2: introduce compression type feature
qcow2: rework the cluster compression routine
qcow2: add zstd cluster compression
iotests: 287: add qcow2 compression type test
