qemu: snapshot: Properly handle image locking
Images that became the backing chain of the current image due to the snapshot need to be unlocked in the lock manager. Also if qemu was paused during the snapshot the current top level images need to be released until qemu is resumed so that they can be acquired properly.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
