Based on a warning from coverity. The safe* functions guarantee complete transactions on success, but don't guarantee freedom from failure. * src/util/util.h (saferead, safewrite, safezero): Add ATTRIBUTE_RETURN_CHECK. * src/remote/remote_driver.c (remoteIO, remoteIOEventLoop): Ignore some failures. (remoteIOReadBuffer): Adjust error messages on read failure. * daemon/event.c (virEventHandleWakeup): Ignore read failure.
