In GetInvInt(int) function, malicious content can access memory
outside of the invCount array. Always bound access to valid
indices.
Test: see bug for malicious content, decoded with "stagefright -s -a"

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.

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.

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.
