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.

* commit 'f2df045a':

* commit '2b6bf8dc':
  Do not include genericStds_linux.cpp.

The __aeabi_memcpy functions are already defined in Android libc.
Redefining them to call memcpy will become recursive when clang/llvm
converts the memcpy call to __aeabi_memcpy.
With this change, we can enable clang/llvm by removing LOCAL_CLANG from Android.mk.

* commit '66091e46':
  Fix checks for {Front,Side,Back}ElementIsCpe

* commit '84851b23':
  Move back to C++98.

{Front,Side,Back}ElementIsCpe is an array (per-channel). The check for
pPce->{Front,Side,Back}ElementIsCpe without an index checks the address
of the array, and will always evaluate to true. The elTagSce++
statements are unreachable.

This code depends on narrowing hex literals to a signed long, which
trips -Wc++11-narrowing (the fix would be to explicitly cast each
value to signed).

  [MIPSR6] Skip assembler code using MFHI/MFLO on mips32r6

Change-Id: I3dacd96cf9d5cf9c3d34d612ebb0456d64bc23bc

Revise decoder output delay determination. The output delay consisted of
  concealment and limiter delay. SBR delay was not covered but must be
  considered for gapless playback delay compensation.

* commit '35f30c5a':
  AArch64: Make LONG 4 bytes

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.

* commit '3252951f':
  Temporary workaround for 64-bit build error

Replace #error by #warning so we can build 64-bit

Change-Id: Ib52fbfb0e5e945ff04ba51ae06b4e3393886d7b7

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.

   - 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
