Original commit message from CVS:
* configure.ac:
Add imagemixer/dvdsubdec.

it up and can still validly emit no-more-pads.

Example.

* gst/imagemixer/plugin.c: (plugin_init):
Image-mixing element, in the style of the pango textrendering
element, but image- instead of text-based, including all cool
stuff like seeking, overlays, picture-in-picture, DVD subtitle
support, text subtitle support and everything. Can do negative
z-orders for inverted overlay (force to AYUV in that case) so
it can be used for chroma-keying software, too (#166783).
* gst/imagemixer/test-dvd-subtitle.sh:
Example.

* gst/mpegstream/gstdvddemux.h:

Implement no-more-pads if the source knows the amount of pads,
which dvd sources known from the IFO files.

Implement subpicture pad support.
* gst/playback/gstplaybin.c: (gen_video_element),
(gen_subtitle_element), (gen_audio_element), (remove_sinks),
(add_sink), (setup_sinks):
Changes so we support subtitles in a more generic way and thus
support DVD subtitles and menus in addition to text subtitles.
* gst/playback/gststreaminfo.c: (gst_stream_type_get_type):
* gst/playback/gststreaminfo.h:
Subpicture type.
* gst/playback/gststreamselector.c: (gst_stream_selector_chain):
Event handling.
* gst/videomixer/videomixer.c: (gst_videomixer_fill_queues),
(gst_videomixer_update_queues):
Do EOS correctly for endless streams on mainpad, while other
pads are infinite (e.g. single picture; #309179).
