Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

Andreas Rheinhardt	dc4c9744eb	avcodec/imm4: Reduce the size of tables used to initialize VLCs By switching from ff_init_vlc_sparse() to ff_init_vlc_from_lengths() one can remove arrays of codes in cases where there were already symbols tables.
