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.

Fixes a segfault with the emu edge flag, since emu edge buffer is now
allocated as a part of the frame buffer allocation and cavs calls
ff_get_buffer() directly, it does not use mpegvideo buffer management.

Some invocations include a verb in the log message, others do not. Yet
av_log_missing_feature expects callers to provide a verb. Change the

function invocations.
