wm4 1fde09db6f Remove some demuxers and decoders
Most of these demuxers and decoders are provided in better form by
libav, while the mplayer builtin ones are essentially unmaintained. The
only legimitate use case for not using the libav ones was working around
libav bugs or bugs related to the way mplayer uses libav. Instead of
trying to keep dead code alive, development effort should go into
improving libav or the mplayer libav glue code.

Note that the libav demuxer have been preferred over the mplayer builtin
ones for a while in mplayer2. There were some exceptions: playing DVDs
with dvdnav or playing network sources. (That's because some stream
modules and network.c requested explicit file formats, such as
DEMUXER_TYPE_MPEG_PS, which mapped to builtin demuxers.) With this
commit, they are switched to use libav. One caveat is that the requested
format is not passed to libavformat, instead we rely on the auto probing
to select the correct libav demuxer (see code in demux_open_stream()).

* An autodetection based on the extension is not a good idea, but we don't care ;-)
*
* You should not add anything here where autodetection can be easily fixed except in
* order to speed up auto-detection, in particular for formats that are often streamed.
* In particular you should not normally add any DEMUXER_TYPE_LAVF, adding the
