4834f01bdf Fix aacDecoder_drcExtractAndMap()
Parse DVB DRC data only when numThreads is below
 MAX_DRC_THREADS. The post-increment is necessary as
 it is used in fill element DRC data section.
This solution parses as many DRC payloads as allowed by
 MAX_DRC_THREADS and skips all remaining DRC elements in the stream.

e46ff0f7f9 Fix stack corruption happening in aacDecoder_drcExtractAndMap()
In the aacDecoder_drcExtractAndMap() function, self->numThreads
  can be used after having exceeded its intended max value,
  MAX_DRC_THREADS, causing memory to be cleared after the
  threadBs[MAX_DRC_THREADS] array.
The crash is prevented by never using self->numThreads with
  a value equal to or greater than MAX_DRC_THREADS.
A proper fix will be required as there seems to be an issue as
  to which entry in the threadBs array is meant to be initialized
  and used.

6e8330732f Remove __DATE__/__TIME__
Building __DATE__/__TIME__ into the binaries means that every build will
create different binaries, even if all the sources are identical. This
also means that any libraries including this one will need to be patched
during every OTA.

Nothing appears to use the build_date/build_time fields, so just replace
them with empty strings.

603f48ab99 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.

34ce250e90 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.
