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.

cbb6ba2e86 avcodec/cavsdec, h264*, hevc_parser: Use get_ue_golomb_31 where possible 
instead of get_ue_golomb(). The difference between the two is that the
latter also has to take into account the case in which the read code is
more than 9 bits (four preceding zeroes + at most five value bits) long,
leading to more code.

7ea1b3472a lavc: deprecate the use of AVCodecContext.time_base for decoding 
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.

Add a new field, called 'framerate', to replace the use of time_base for
decoding.
