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.

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.

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. Modify autoplug_select so that we can try, skip or expose the autopluggin of an element on a pad. * gst/playback/gstfactorylists.c: (compare_ranks), (decoders_filter), (sinks_filter), (gst_factory_list_is_type), (element_filter), (gst_factory_list_get_elements), (gst_factory_list_debug), (gst_factory_list_filter): * gst/playback/gstfactorylists.h: Simplify the API, allow getting elements based on mask. * gst/playback/gstplay-marshal.list: Add some more marshallers. * gst/playback/gstplaybin2.c: (init_group), (gst_play_bin_init), (gst_play_bin_finalize), (pad_removed_cb), (autoplug_factories_cb), (autoplug_select_cb), (activate_group): Add support for managing non-raw sinks by providing a custom element and sink list to decodebin2. Try to plug non-raw sinks when decodebin2 using autoplug-select of decodebin2. * gst/playback/gstplaysink.c: (gen_video_chain), (gen_audio_chain), (gst_play_sink_set_mode), (gst_play_sink_request_pad): * gst/playback/gstplaysink.h: Add support for raw and non-raw sinks. Add support to force sinks selected by playbin2. Don't plug raw converters for non-raw sinks. * gst/playback/gsturidecodebin.c: (_gst_array_accumulator), (_gst_select_accumulator), (gst_uri_decode_bin_class_init), (proxy_autoplug_select_signal), (gst_uri_decode_bin_plugin_init), (plugin_init): Use right accumulators. Proxy new signal.
