Original commit message from CVS: * ext/speex/gstspeex.c: (plugin_init): * ext/speex/gstspeexenc.c: (gst_speex_enc_get_formats), (gst_speex_enc_setup_interfaces), (gst_speex_enc_base_init), (gst_speex_enc_class_init), (gst_speex_enc_finalize), (gst_speex_enc_sink_setcaps), (gst_speex_enc_convert_src), (gst_speex_enc_convert_sink), (gst_speex_enc_get_query_types), (gst_speex_enc_src_query), (gst_speex_enc_sink_query), (gst_speex_enc_init), (gst_speex_enc_create_metadata_buffer), (gst_speex_enc_set_last_msg), (gst_speex_enc_setup), (gst_speex_enc_buffer_from_data), (gst_speex_enc_push_buffer), (gst_speex_enc_set_header_on_caps), (gst_speex_enc_sinkevent), (gst_speex_enc_chain), (gst_speex_enc_get_property), (gst_speex_enc_set_property), (gst_speex_enc_change_state): * ext/speex/gstspeexenc.h: Miscellaneous clean-ups, among other things: speexenc => enc to enhance code readability; change speexenc => speex_enc; in chain function unref input buffer in case of error; take reference in event function; use boilerplate macro; use gst_pad_query_peer_* convenience functions.
