Subject: Bug 7170947 Update AAC codec

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.
     Modified file(s):
        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.
     Modified file(s):
        libFDK\include\mips\cplx_mul.h
        libFDK\include\mips\fixmul_mips.h
