For both the RealMedia as well as the IVR demuxer (which share the same context) each AVStream's priv_data contains an AVPacket that might contain data (even when reading the header) and therefore needs to be unreferenced. Up until now, this has not always been done: The RealMedia demuxer didn't do it when allocating a new stream's priv_data failed although there might be other streams with packets to unreference. (The reason for this was that until recently rm_read_close() couldn't handle an AVStream without priv_data, so one had to choose between a potential crash and a memleak.) The IVR demuxer meanwhile never ever called read_close so that the data already contained in packets leaks upon error. This patch fixes both demuxers by adding the appropriate cleanup code.
