[libvirt] [PATCH 00/16] Implement post-copy migration

(See "Add public APIs for post-copy migration" patch for more details about post-copy migration.) Post-copy support was originally written by Cristian Klein in 2014, but no one touched the series since then. Some patches in this series are modified versions of the old patches from Cristian, some patches had to be rewritten from scratch since libvirt code changed a lot (we started using migration events), and some patches are completely new. While post-copy migration is included in QEMU 2.5.0, it didn't support everything libvirt needs. Thus you need QEMU from git to use post-copy. Luckily, the QEMU migration capability we need to enable to use post-copy is still prefixed with "x-", which means it's still considered experimental. Once we are sure QEMU gives us all we need, the "x-" prefix will be removed. Seamless SPICE migration doesn't work with post-copy now, but I'll look at that. This series (VIR_MIGRATE_POSTCOPY_AFTER_PRECOPY support) depends on "Introduce migration iteration event" series I sent yesterday.
