In gst_hls_demux_get_next_fragment() the next fragment URI gets stored in next_fragment_uri, but the gst_hls_demux_updates_loop() can at any time update the playlist, rendering this string invalid. Therefore, any data (like key, iv, URIs) that is taken from a GstM3U8Client needs to be copied. In addition, accessing the internals of a GstM3U8Client requires locking. https://bugzilla.gnome.org/show_bug.cgi?id=737793
