BMediaFiles and about BMediaTracks in BMessages. As an
example, one can get chapter meta-data or the language
name of an audio-track.

* Added myself to copyrights, since I added some stuff to MediaExtractor.

regards to locking and seeking.
* Furthermore, we now not only cache 4 chunks, but chunk up to a certain
memory size (MediaExtractor uses 1 MB for now).
* Since I still have occasional hickups, it looks like this wasn't the main
cause for our audio problems. Still, this will reduce drive access
considerably during play.

- Implemented BMediaFile::Copyright, which just calls Copyright() of the extractor. So this is just a simple pass through.
- Style cleanup (mostly whitespaces)
Problem is that our readers currently return the copyright of the source code, not the copyright of the MediaFile itself, like the BeBook documents. Thus, we might need to change all readers to return appropiate data or behave differently for Haiku readers.

but operates "read-only".
* Added FindKeyFrame() method to ReaderPlugin, see above.
* Reformated ReaderPlugin header. Added const qualifier to Source() method.
* Small cleanups in BMediaTrack::SeekToTime() and SeekToFrame(). Added TODOs
with regards to "seeking" in decoders, wich should IMHO be revised. (Codecs
cannot seek in the stream, they only get fed chunk data. The only thing they
can do is reset themselves in preparation for a discontinuity of the chunk
data...)
* Implemented BMediaTrack::FindKeyframeByXX() methods via the new
MediaExtractor::FindKeyFrame() method.
* Implemented Seek() and FindKeyFrame() methods in the Reader base class,
returning B_NOT_SUPPORTED. I think this makes sense and also I don't have
to adapt all existing Reader plugins for the new FindKeyFrame() call. :-)
* Implemeneted FindKeyFrame() in the avi_reader. The OpenDMLFile class
gets Seek() extended for a "read-only" mode. Currently the implementation
is broken (as before) with regards to keyframes. These were ignored before
and I have not changed them to actually support the seek flags with regards
to keyframes. That's the interesting TODO...
* Some reformatting here and there in avi_reader code, sorry for the mixup.
The only actual change is the support for the read-only flag to Seek().

We now use "const" for the chunk buffer pointer returned by GetNextChunk,
because the buffer is not supposed to be modified by the codec.
size_t is used for the size where applicable. This matches BMediaDecoder.

the ReadFrames call no longer needs to wait for the
extractor, but can read it from a cache.
