recalculation (spotted by KKI).

needs to get a sane default size and some cleanups of the code, but I commit
now in case anyone wants it during cristmas

- make it working again with daily CVS snapshot.
- some typos fixed.
- better workaround for broken mdk configure macro (aka don't harcore arch in name).

* modules/codec/vorbis.c: parse the vorbis comment (can anyone tell me why the
comment is embedded in the logical stream and not directly in the
container?). The vorbis comments are in utf8, so extended characters
currently get messed up.

Still tring to close #51

towards closing bug #51. Type 'info' in the rc interface to test.

* src/libvlc.h, src/input/input_dec.c: added an "sout-video" and
"sout-audio" config option that allows to selectively enable audio or
video stream output. This is very useful if you want to play video on
one computer and audio on another one ;)

received an header (vol). (It prevents some segfaults with mpeg4 streaming).

Becareful that up to now, it's more a hack. (I need to add SL streams
managments)

    corrupted headers.

header.

    tells what libavcodec build it was built with.
