Ping for this series.
Patch #13 conflicts with Mira's proposed change for copying the
conntrack information[0].
Patch #1 and Patch #5 are the only ones *not* conflicting with Fabian's
remote migration RFC[1].

This series intends to make the migration code more readable by
simplyfing/unifying how we keep track of local volumes and splitting up
sync_disks into multiple subroutines.
This is done by keeping more information within the hash of local_volumes we
obtain in the very beginning and re-using it later. Also a method to filter by
migration/replication type is introduced, making it possible to get rid of some
special-case handling when iterating over local volumes.
Still more should be possible, but the series is getting big, so I stopped here.
Namely, $self->{local_volumes}, $self->{volume_map} and $self->{target_drive}
still have some overlap and it might be possible to merge them somehow.
Also it might make sense to put abstract more things to the common code, one
example is to make target storage mapping available for containers too.
Changes from v1:
* dropped already applied patches
* rebased
* prefix commit messages with 'migration' (and 'test')
* increased test coverage a little, see patch #1 and patch #13
* reordered patches #8+#9 to avoid temporary breakage, see
patches #8 and patch #13 (added test-case) for the details
* add patch to fix bandwidth limit calculation
* add patch to split out run_replication from scan_local_volumes
* add patch to improve error handling when block job finishing fails

test: migration: add parse_volume_id calls
migration: split sync_disks into two functions
migration: avoid re-scanning all volumes
migration: split out config_update_local_disksizes from
scan_local_volumes
migration: fix calculation of bandwith limit for non-disk migration
migration: save targetstorage and bwlimit in local_volumes hash and
re-use information
migration: add nbd migrated volumes to volume_map earlier
migration: simplify removal of local volumes and get rid of
self->{volumes}
migration: cleanup_remotedisks: simplify and include more disks
