avcodec/internal: Move FF_SIGNBIT and ff_log2_run to mathops.h
...
It is a more fitting place for them.
Also move the definition of ff_log2_run to mathtables.c.

avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.h
...
Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault.
This reduces the amount of files that have to include internal.h
(which comes with quite a lot of indirect inclusions), as e.g.
most encoders don't need it. It is furthemore in preparation
for moving the private part of AVCodec out of the public codec.h.

The encoder was reverse engineered from binary library and from
EP0398973B1 patent (long expired).
The decoder was simply deduced from the encoder.
