memory: add ref/unref calls
Add ref/unref calls at the following places: - places where memory regions are stashed by a listener and used outside the BQL (including in Xen or KVM). - memory_region_find callsites - creation of aliases and containers (only the aliased/contained region gets a reference to avoid loops) - around calls to del_subregion/add_subregion, where the region could disappear after the first call Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
