[libvirt] [PATCH 0/3] QEMU directory/monitor socket fixes/cleanup

This patch series does three things - Moves QEMU monitor sockets in /var/lib/libvirt/qemu, since this is created file and thus should be separate from libvirtd created data to avoid risk from QEMU compromise. - Sets QEMU directory ownership to match configured qemu user/group - Fixes a minor memory leak / socket unlink
