An overflow in the fft was observed for certain configurations. The root cause was in the scaling of the fft input data in dct_IV and dst_IV.
The following patch revises the scaling in dct and removes the unused arm implementation.

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.

(cherry picked from commit 15292f7e96)
Clang warns about this being deprecated, when building without specifying
-std=c++98.
This doesn't give any measurable encoding speed impact on ARM or AArch64,
on neither GCC nor Clang.

This fixes building in C++11 mode, which normally errors out
on narrowing hex literals to signed long.
This is similar to what was done in git commit ef30836651
(change id I64d19a8a8059c5a96386b1eaac297fd2469515f8), completing
the fix for that category of issues.

Building __DATE__/__TIME__ into the binaries means that every build will
create different binaries, even if all the sources are identical. This
also means that any libraries including this one will need to be patched
during every OTA.
Nothing appears to use the build_date/build_time fields, so just replace
them with empty strings.

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.

* 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.
