This avoids intermediates from overflowing (the final values are checked)
Fixes: runtime error: signed integer overflow: -167712 + -2147352576 cannot be represented in type 'int'

Aliased compressed AAC bytes are almost certainly not meaningful SBR
data. In the wild this causes harsh artifacts switching HE-AAC streams
that don't have SBR headers aligned with segment boundaries.
Turning off SBR falls back to a default set of upsampling parameters
that can function as a sort of error concealment. This is consistent
with how the decoder handles other sorts of errors.

This allows fuzzing decoders with the same codec_id
We also avoid register all to allow the linker to prune unused sections and symbols

h264dec: make sure to only end a field if it has been started
This commit is a noop. Our h264 slicing handling is different and does
not seem to be affected by the issue.

Because write_packet() fakely writes packets to muxer by queueing
them when muxer hasn't been initialized, it should also increment
frame_number fakely.
This is required because code in do_streamcopy() rely on
frame_number.
Should fix Ticket6227

This makes the currently semi-public avpriv_aac_parse_header() function
private to libavcodec and adds a proper public API function to return
the parts of the ADTS header required in libavformat.
Decreases the time spend decoding junk.
