18e55de45a avcodec/aptx: Move AudioFrameQueue to aptxenc.c
It is only used by the encoder.

86c909558c 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.

a688f3c13c 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.

a337b36b8b aptx: implement the aptX bluetooth codec
The encoder was reverse engineered from binary library and from
EP0398973B1 patent (long expired).
The decoder was simply deduced from the encoder.
