AAC Decoder: introduce time domain limiter
Introduce time domain limiter. The module is per default enabled for all
AAC-LC and HE-AAC v1/2 streams. For all ER-AAC-LD and ER-AAC-ELD streams
the limiter is disabled per default. The feature can be en- or disabled
via dynamic API parameter. Note that the limiter introduces an additional
output delay which depends on the module parameters and the streams
sampling rate.

Bug 7170947 Update AAC codec
From Fraunhofer:
* AAC Decoder
- Stick to the written MPEG standard instead of the MPEG reference software
in terms of reference level normalization. Always set the program reference
level equal to the target level. This disables level normalization using a
default level for streams without embedded metadata.

needs to be done.

Don't zero out spec coeffs before doing the final IMDCT.
Addresses bug 7140347.
When flushing the decoder, you need to make sure to zero out any
lingering spectral coefficients as well as zero out the overlap buffer
state after decoding the final access unit. Zeroing out the spec
coefficients *before* you decode the last block, however, seems like a
mistake. If the final block contains any useful information for the
stream, then you end up outputting the overlap portion of the second
to last decoded block combined with zeros. Because of the shape of
the second to last block's windows, this results in what appears to be
a fade out, but actually is a zero'ed out final block.
