Original commit message from CVS: * ext/lame/gstlame.c: (gst_lame_sink_link), (gst_lame_init), (gst_lame_chain), (gst_lame_setup), (gst_lame_change_state), (plugin_init): add debugging category, add error checks like checking return values of setup calls, make sure it still works after PLAYING=>NULL=>PLAYING, fix encoding of mono streams
