Original commit message from CVS: * ext/vorbis/vorbisenc.c: (gst_vorbis_enc_generate_sink_caps), (gst_vorbis_enc_sink_getcaps), (gst_vorbis_enc_buffer_from_packet), (gst_vorbis_enc_push_buffer), (gst_vorbis_enc_buffer_check_discontinuous), (gst_vorbis_enc_chain), (gst_vorbis_enc_change_state): * ext/vorbis/vorbisenc.h: Handle discontinuities in the input vorbis stream correctly, so that the output is properly timestamped (and has good granulepos values). Needs some oggmux fixes too.
