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.

- Add 6.1 and 7.1 channel support including downmixer. Per default the
decoder creates a 5.1 channel output for all streams with more than six
encoded channels.

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.
Modified file(s):
libAACdec\src\aacdec_drc.cpp
- Fix downmix channel assignment when using a WAV output channel ordering.
Modified file(s):
libPCMutils\src\pcmutils_lib.cpp
- Retain signal accuracy and prevent LSB alteration when no level correction
needs to be done.

libAACdec\src\aacdec_drc.h
libAACdec\src\aacdec_drc.cpp
libSBRdec\src\sbrdecoder.cpp
libSBRdec\src\sbr_dec.cpp
libSBRdec\src\sbrdec_drc.cpp
- Align metadata processing with reference implementation.
Modified file(s):
libAACdec\src\aacdec_drc.h
libAACdec\src\aacdecoder.cpp
* AAC-Encoder
- Prevent potential overflow in energy calculation after TNS processing.
Modified file(s):
libAACenc\src\band_nrg.cpp
- Added saturation for number of relevant lines which are used in pe
calculation.
Modified file(s):
libAACenc\src\line_pe.cpp
- Removed obsolete files.
Deleded file(s):
libAACenc\src\tns_param.h
libAACenc\src\tns_param.cpp
* FDK-Library
- Added x86 Count Leading Zeros intrinsic.
Modified file(s):
libFDK\include\clz.h
Added file(s):
libFDK\include\x86\clz_x86.h
- Fixed compilation for MIPS GCC-4.4 and higher.
