48b330d303727e1f2671f844a1d541d596f6d5da 22-Oct-2015 Dan Willemsen <dwillemsen@google.com> Remove __DATE__/__TIME__

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.

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.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

* 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.
