Add knobs to virsh to manage a 2-phase active commit of the top layer, similar to knobs already present on blockcopy. While this code will fail until later patches actually implement the new knobs in the qemu driver, doing it now proves that the API is usable and also makes it easier for testing the qemu changes as they are made.
* tools/virsh-domain.c (cmdBlockCommit): Add --active, --pivot, and --finish options, modeled after blockcopy. (blockJobImpl): Support --active flag. * tools/virsh.pod (blockcommit): Document new flags. (blockjob): Mention 2-phase commit interaction.

This doesn't depend on anything qemu-specific and thus is safe to push async. ACK. Peter
