- enable the parsing code
- use the new buffer instead of replacing the context one
- do not push/pop configuration, just discard the exiting one
- propagate errors correctly
This will result in poor quality audio for SSR streams, but they
will at least demux and decode without error; partially fixing
ticket #1693.
This pulls in the decode_gain_control() function from the
ffmpeg summer-of-code repo (original author Maxim Gavrilov) at
svn://svn.mplayerhq.hu/soc/aac/aac.c with some minor modifications
and adds AOT_AAC_SSR to decode_audio_specific_config_gb().

Apparently the demuxer outputs the wrong padding for HE-AAC (based on
the raw sample rate, or so). aacdec contains a hack to adjust the muxer
padding accordingly before it's used to trim the decoder output. This
modified the packet side data, which in combination with the old
decoding API would change the packet the user passed to the decoder.
This is clearly not allowed, and it breaks running some gapless fate
tests with "-fflags +keepside" applied (without keepside, the packet
metadata is typically newly allocated, essentially making a copy and not
modifying the user's input packet).
This should probably be fixed in the demuxer (and consequently also the
muxer), but for now only fix the immediate problem.
Regression since 946ed78f5f (2012).
Handles strides (needed for Opus transients), does pre-reindexing and folding
without needing a copy.

A strict reading of the spec seems to imply that it should be aligned to
the start of the element instance tag, but that would break all of the
samples with PCEs.
It seems like a well formed LATM stream should have its PCE in the ASC
rather than inband.

There was fixed number of loops (2048) in preparation for resampler, so
when number of samples is smaller than this, there would be an overflow on
ret_buf.
For some reason this behavior popped out only under valgrind with
--disable-memory-poisoning option.
This is now fixed and number of loops depends on actual number of samples.
