Henrik Kjellander f49fde796f Use DEPS for all dependencies + add PRESUBMIT.py 
This changes libyuv to use the DEPS file for pulling
down all dependencies (thus no Chromium checkout is needed any more).

Add tools_libyuv directory to contain libyuv-specific tools
(needed to avoid name collision with the now DEPSed tools/ directory
of Chromium, which is needed by the toolchain).
Add tools_libyuv/autoroller/roll_deps.py script to automatically
roll all entries in the DEPS file (copied from WebRTC).

third_party/ is now DEPSed as well, including the gtest configuration
headers that used to live inside the libyuv repo.

Add PRESUBMIT.py with a few simple checks + execution of PyLint and
Python unit tests. For PyLint a pylintrc file was also added.

Valgrind in tools_libyuv/valgrind was updated to make PRESUBMIT.py pass
and remove old tsan suppressions (not used).

Removed util/android/test_runner.py since it's no longer needed.

Buildbot changes in https://chromium-review.googlesource.com/436464 
are needed for the Memcheck bot to go green.

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats.
  • Convert from YUV to formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSE2/SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for DSP R2 on Mips.
