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	d8fc69bd6a	avcodec/indeo5: Fix memleaks upon allocation error ff_ivi_init_planes() might error out after having allocated some arrays. Set the FF_CODEC_CAP_INIT_CLEANUP flag in order to free these arrays in this case.
