gst/playback/: Add playbin2. Original commit message from CVS: * gst/playback/Makefile.am: * gst/playback/gstplayback.c: (plugin_init): * gst/playback/test7.c: (update_scale), (warning_cb), (error_cb), (eos_cb), (about_to_finish_cb), (main): Add playbin2. Added gapless playback example. * gst/playback/gstplaybasebin.c: * gst/playback/gstplaybasebin.h: * gst/playback/gstplaybin.c: (gst_play_bin_plugin_init): * gst/playback/gstqueue2.c: * gst/playback/test.c: * gst/playback/gsturidecodebin.c: (gst_uri_decode_bin_class_init), (pad_removed_cb): * gst/playback/gststreaminfo.h: Change email. * gst/playback/gstplaybin2.c: (gst_play_bin_get_type), (gst_play_bin_class_init), (init_group), (gst_play_bin_init), (gst_play_bin_dispose), (gst_play_bin_set_uri), (gst_play_bin_set_suburi), (gst_play_bin_set_property), (gst_play_bin_get_property), (gst_play_bin_handle_message), (pad_added_cb), (pad_removed_cb), (no_more_pads_cb), (perform_eos), (drained_cb), (unlink_group), (activate_group), (setup_next_source), (gst_play_bin_change_state), (gst_play_bin2_plugin_init): Added raw first version of playbin2. Does chained oggs and gapless playback fine. No support for raw sinks yet. No visualisations or subtitles yet. * gst/playback/gstplaysink.c: (gst_play_sink_get_type), (gst_play_sink_class_init), (gst_play_sink_init), (gst_play_sink_dispose), (gst_play_sink_vis_unblocked), (gst_play_sink_vis_blocked), (gst_play_sink_set_video_sink), (gst_play_sink_set_audio_sink), (gst_play_sink_set_vis_plugin), (gst_play_sink_set_property), (gst_play_sink_get_property), (post_missing_element_message), (free_chain), (add_chain), (activate_chain), (gen_video_chain), (gen_text_element), (gen_audio_chain), (gen_vis_element), (gst_play_sink_get_mode), (gst_play_sink_set_mode), (gst_play_sink_request_pad), (gst_play_sink_release_pad), (gst_play_sink_send_event_to_sink), (gst_play_sink_send_event), (gst_play_sink_change_state): * gst/playback/gstplaysink.h: Added Element that abstracts the sinks and their pipelines for playbin2.

Original commit message from CVS: * gst/playback/Makefile.am: Group decodebin2 and uridecodebin into the same plugin so that they can share the GEnumType. * gst/playback/gstdecodebin2.c: (_gst_array_accumulator), (_gst_select_accumulator), (gst_decode_bin_class_init), (gst_decode_bin_init), (gst_decode_bin_autoplug_sort), (gst_decode_bin_autoplug_select), (gst_decode_bin_autoplug_add), (analyze_new_pad), (connect_pad), (gst_decode_bin_plugin_init): Add signal to sort factories instead of the more awkward autoplug-select signal.

Rename some internal enum declarations (audioconvert's DitherType and NoiseShapingType, GstUnitType from the TCP elements) to match the documented GObject type names so that the docs pick them up. Name the playbin2 docs markups properly so they get picked up. They'll need renaming back when/if playbin2 becomes playbin. 100% symbol coverage for the plugin docs, booya.
