[libvirt] [PATCH v2 00/12] qemu: migration: show disks stats for nbd migration

diff from v1: ============ 1. patch "qemu: clean out unused migrate to unix" is dropped as it is already pushed. 2. a lot of refactoring patches added, namely all except the last patch. 3. fetching mirroring stats is done separately from getting migration status. Generally speaking refactorings patches removes the function to fetch migrations status altogether. Current migration stats will show something like [1] when in the process of mirroring of non shared disks. This gives very little info on the migration progress. Likewise completed stats miss disks mirroring info. This patch provides disks stats in the said phase like in [2] so user can now understand what's going on. However data stats miss memory stats, so data total and remaining will change when memory migration starts. AFAIU disks stats were available before the nbd based migration becomes the default. So this patch returns disks stats back at some level.
