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.

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.

aac project forces the system not to include sys/types.h by defining
_SYS_TYPES_H_. This is a workaround for broken android toolchain.

This is no longer needed in latest android version and can be safely
removed. This will also lead to more errors if changes in bionic
headers are needed.

Shifting by more than (or equal to) the variable length is
undefined in C.

This caused the quantized spectrum values to go out of range,
triggering asserts later.
