Jean-Michel Trivi 4834f01bdf Fix aacDecoder_drcExtractAndMap() 
Parse DVB DRC data only when numThreads is below
 MAX_DRC_THREADS. The post-increment is necessary as
 it is used in fill element DRC data section.
This solution parses as many DRC payloads as allowed by
 MAX_DRC_THREADS and skips all remaining DRC elements in the stream.

Jean-Michel Trivi a06d1c2b9a Fix stack corruption happening in aacDecoder_drcExtractAndMap() 
In the aacDecoder_drcExtractAndMap() function, self->numThreads
  can be used after having exceeded its intended max value,
  MAX_DRC_THREADS, causing memory to be cleared after the
  threadBs[MAX_DRC_THREADS] array.
The crash is prevented by never using self->numThreads with
  a value equal to or greater than MAX_DRC_THREADS.
A proper fix will be required as there seems to be an issue as
  to which entry in the threadBs array is meant to be initialized
  and used.

Dan Willemsen 2d435aa433 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.

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.
