While testing FDK in Android P DP3 x86 64bit emulator we observed a runtime error.
The function parameter of the callback didn't use a typeless pointer.
Following patch contains a revised sbr decoder callback function with explicit data type cast to be inline with all other callbacks in FDK.

While long-term test we discovered a bit counter overflow in the bit buffer.
The bit buffer state was only used by HCR and RVLC tool and can easily be substituted with FDKgetValidBits() call.
The following patch completely removes the bit counter and all its obsolete functions.

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.

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.

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.
