avcodec/codec_par: add side data to AVCodecParameters

Browse Source 
This will simplify the propagation of side data to decoders and from encoders.
Global side data will now reside in the AVCodecContext, thus be available
during init(), removing the need to propagate it inside packets.

Global and frame specific side data will therefore be distinct.
