AAC-Decoder: SBR delay for gapless
Revise decoder output delay determination. The output delay consisted of
concealment and limiter delay. SBR delay was not covered but must be
considered for gapless playback delay compensation.

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.

* 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.

- Fix downmix channel assignment when using a WAV output channel ordering.
Modified file(s):

needs to be done.
