John Budorick 33503d9c9c Fix libyuv deps autoroll and roll chromium deps. 
This includes:
  - fixing a handrolled raw exec-based DEPS parser that was failing
    to parse Str, similar to crbug.com/1106435.
  - rolling chromium forward by nearly a year. (The last roll that
    landed was crrev.com/c/1797295). This required a bunch of changes in
    order to be able to successfully sync, run gn, and compile:
    - switching the mirrors for three repositories to match chromium,
      which switched in crrev.com/c/2062580.
    - making libyuv write an empty gclient_args file
    - adding a few build_override gn arguments
    - adding nasm as a deps entry, as it's now required by libjpeg_turbo
    - android:
      - adding jdk, libunwindstack, and turbine
      - rolling the android sdk
      - rolling bazel and r8
      - rolling the cipd packages managed by third_party/android_deps
      - adding six and requests to .vpython for the test runner
      - switching to memcpy in a few places to avoid SIGBUS errors on
        arm due to unaligned reads
    - linux:
      - checking out instrumented libraries for msan (including adding
        depot_tools to deps for the hook)
    - mac:
      - adding mac_xcode_version to gclient_gn_args
    - win:
      - limit mac_toolchain to checkout_mac

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 for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for MSA on Mips.
