[libvirt] [PATCH 0/5] Selective block device migration implementation

The patchset represented in the mail thread implements the selective block device migration for the QEMU driver. This closes the referenced bug [1]. First the supplementary API implemented allowing for multiple key-values pair in the virTypedParameter arrays. This is used to pass the list of block devices to migrate in the following patches. Unit tests for this are added as well. This is the subject of the first three patches. Fourth patch is adding the necessary parameter `migrate_disks' and passes it through the QEMU driver call stack. The introduced `qemuMigrateBlockDevice' function is then checks that the disk is to be migrated because it is in the list. If there is no list specified then the legacy check is used: the device is not shared, not readonly and has a source. Fifth and the last patch is adding the necessary code to the `virsh' utility making it able for user to specify a comma-separated list of the block device names that are to be migrated. The implemented Python bindings patch is to be presented.
