* qemu: Add 'sparse' as a new save image format
QEMU's ``file`` migration has been supplemented with the new stream format
``mapped-ram``, where RAM pages are mapped directly to offsets in the
migration file. ``mapped-ram`` is now supported by augmenting the existing
save image formats with the ``sparse`` format.
* qemu: Add support for parallel save/restore
The ``sparse`` image format can support reading and writing by multiple
channels. ``virDomainSaveParams`` and ``virDomainRestoreParams`` now
support specifying the number of IO channels used for parallel save and
restore. Using multiple channels can reduce the time required to save
and restore domains.
