[libvirt] [RFC: PATCH 00/13] live block migration via virDomainBlockCopy

This is in response to my discussion with Paolo here: https://www.redhat.com/archives/libvir-list/2012-March/msg01171.html It also picks up an old patch from Adam here (now split into two): https://www.redhat.com/archives/libvir-list/2012-January/msg00562.html Patches 1-12 are in pretty good shape, while patch 13 is still a work in progress. I can test a lot of the pieces, but still have several patches to go before I can fully test the new API. I'm posting this now to at least start some review on the earlier pieces, and to get consensus that the API and XML changes are correct. None of these patches should be applied until after 0.9.11 is released, and even then, we still want confirmation of whether upstream qemu 1.1 will include complete support for block mirroring. For anyone trying to backport this feature to 0.9.10 .so API, I've made sure that you can just omit patches 5 and 6, and that everything else will backport cleanly to give you the new feature through just the public virDomainBlockRebase() call.
