Instead of one track reference, allow multiple. In addition, allow
client to explicitly add track references with side packet
AV_PKG_DATA_TRACK_REFERENCES containing AVTrackReferences. MOVTrack's
track references can be manipulated with helper functions
ff_mov_*tref*.

This encoder is used primarily with ISO media files and basically
copies the data, while allowing the rest of the FFMPEG to refer
to the meta data with its identifiers.

Also added avdata_alloc and avdata_free for dealing with it. AVData
can contain arbitrary binary data and comes with a format-field so far
unused.
The purpose is that AVMEDIA_TYPE_DATA -kind codecs can store frames in
this format.

Now force_codec_ids supports AVMEDIA_TYPE_DATA and
avformat_query_codec accepts data codecs as well in addition to video,
