2019-08-16qapi: implement block-dirty-bitmap-remove transaction actionJohn Snow
It is used to do transactional movement of the bitmap (which is possible in conjunction with merge command). Transactional bitmap movement is needed in scenarios with external snapshot, when we don't want to leave copy of the bitmap in the base image.

2019-01-14block: remove 'x' prefix from experimental bitmap APIsJohn Snow
The 'x' prefix was added because I was uncertain of the direction we'd take for the libvirt API. With the general approach solidified, I feel comfortable committing to this API for 4.0.

2018-10-29qapi: add transaction support for x-block-dirty-bitmap-mergeVladimir Sementsov-Ogievskiy
New action is like clean action: do the whole thing in .prepare and undo in .abort. This behavior for bitmap-changing actions is needed because backup job actions use bitmap in .prepare. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: John Snow <jsnow@redhat.com>
