The dprintf macro shadows a real libc symbol which is called differently, so we should change it to something else (in this case LOGD) and change it to use the libqrtr logging facilities. This also means we should add a minimum priority to the logging library so we don't log DEBUG-level messages by default. Additionally there were some warn/warnx calls left over that have been changed to PLOGW/LOGW respectively.
