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.

Does someone have a valid sample that triggers this path ?

get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes
The merge commit also includes changes for libavcodec/interplayacm.c and
libavcodec/truemotion2rt.c
Merged-by: Clément Bœsch <clement@stupeflix.com>
This avoids the danger that get_bits.h might get indirectly #included before
BITSTREAM_READER_LE is defined.
Also sort headers into canonical order where appropriate.

Do not make many assumption on the dimension of the slices and just
try to decode additional lines if there is enough data left.
Decodes all the samples kindly provided by ultramage.
This is probably unneeded and normal int would be fine, but its
safer to use LL and this isnt speed relevant
