Add reference counting on the virDomainObjPtr objects. With the forthcoming asynchronous QEMU monitor, it will be neccessary to release the lock on virDomainObjPtr while waiting for a monitor command response. It is neccessary to ensure one thread can't delete a virDomainObjPtr while another is waiting. By introducing reference counting threads can make sure objects they are using are not accidentally deleted while unlocked. * src/conf/domain_conf.h, src/conf/domain_conf.c: Add virDomainObjRef/Unref APIs, remove virDomainObjFree * src/openvz/openvz_conf.c: replace call to virDomainObjFree with virDomainObjUnref
