[libvirt] [PATCH 00/10] Get ready for migration events

QEMU will soon get support for migration events which will finally allows us to get rid of polling query-migrate every 50ms. However, we first need to be able to wait for all events related to migration (migration status changes, block job events, async abort requests) at once. This series prepares the infrastructure which will allows us to do it (patches 1 and 2) and then makes use of it for block job events (patch 4) and abort requests (patch 10). Patch 8 fixes a bug in migration recovery after libvirtd restarts. The rest of the patches are mostly cleanups or bugfixes or other small changes required by the 5 main patches.
