Add API to add and get custom headers that are not covered by our header fields enum. This is backwards compatible in that it will also work for our defined fields, so if we ever add a new header field to the enum, get_header_by_name() for the same header string will still work. API: gst_rtsp_message_add_header_by_name() API: gst_rtsp_message_take_header_by_name() API: gst_rtsp_message_remove_header_by_name() API: gst_rtsp_message_get_header_by_name()
