Fraunhofer IIS FDK 9744e41c40 Prevent bit buffer counter overflow. 
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.

Marcus Oakland f2f96fb86d AArch64: Make LONG 4 bytes 
The libSYS/include/machine_type.h header file states LONG should be
"Data type representing 4 byte signed integer on all supported
platforms" but only provided for defining LONG as INT and ULONG as
UINT when __x86_64__ was defined. This has been changed to when
__LP64__ is defined, so that it also applies to AArch64. The change
to libFDK/include/common_fix.h is then needed to get the project to
compile.

Jean-Michel Trivi 6ab36997af 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.

        libSBRdec\src\sbr_dec.cpp
        libSBRdec\src\sbrdec_drc.cpp

   - Align metadata processing with reference implementation.
     Modified file(s):
        libAACdec\src\aacdec_drc.h

* 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.

   - Removed obsolete files.
     Deleded file(s):
