It is decoder-only; furthermore, there is already
an AACContext in use by libfdk-aacenc.
Also make aacdec.h provide the typedef for AACContext;
up until now, this has been done by sbr.h.

The AAC decoders share no common code with the AAC encoder,
so they are not restricted to using the same structures.
This implies that one can use different structs for each
component and remove elements not used by the decoders/
the encoder. This leads to quite sizeable savings:

The wav demuxer by default tried to demux 4096-byte packets which caused
packets with very few number of samples for files with high channel count.
This caused a significant overhead especially since the latest ffmpeg.c
threading changes.
So let's use a similar approach for selecting audio frame
Since PTS is changed randomly for every audio frame, it matters. Also add some

Previously, the following syntax elements were not read in the case
sps_num_subpics_minus is 0:

* sps_subpic_id_mapping_explicitly_signalled_flag
