[libvirt] [PATCH 1/2] Avoid taking lock in libvirt debug dump

As pointed out, locking the buffer from the signal handler cannot been garanteed to be safe, so to avoid any hazard we prefer the trade off of dumping logs possibly messed up by concurrent logging activity rather than risk a daemon crash. * src/util/logging.c: change virLogEmergencyDumpAll() to not take any lock on the log buffer but reset buffer content variables to an empty set before starting the actual dump.
