Uprev webrtc-apm to upstream WebRTC M88

This change is created by:
1. ./script/sync-apm.sh <webrtc branch-heads/4324> .
2. Modify modules.mk files until everything compiles
Note that some aec3 targets with avx2 optimizations are moved to
modules/audio_processing/aec3/module.mk. The purpose is to avoid
codes without avx2 intrinsics be compiled with -mavx2 which
seems to cause crash on GLK platforms.
3. Re-apply commit 1a11b8a webrtc-apm: Replace deprected Json::Reader call.

BUG=b:175761810
TEST=emerge webrtc-apm and deploy
Execute 'cras_test_client -C /dev/null --effects aec' to verify
on hatch, octopus, grunt, atlas, kalista

WebRTC APM

APM is the audio processing module of WebRTC project in charge of effects like echo cancellation, noise suppression, etc. The purpose of this project is to build a standalone library for Chrome OS system side audio processing.

Files content

  • scripts to copy over folders and files from upstream WebRTC project for APM and its dependencies.
  • Copied files from upstream WebRTC project. For example: common_audio, modules, rtc_base and system_wrappers.
  • webrtc_apm.cc/h C wrappers to access APM functions.
  • common-mk based makefiles to build shared library libwebrtc_apm.so

Update

To update this package to latest upstream WebRC:

  • Run ./script/sync-apm.sh path/to/webrtc-checkout/src .
  • emerge webrtc-apm to see if anything breaks.
  • If emerge success, then we're good.
  • Otherwise look into the emerge failure, and then possibly:
    • Update sync-apm.sh to copy more files if upstream directory structure changes.
    • Update makefiles if upstream build files has changed.
    • Update webrtc-apm ebuild file if dependencies changed.
  • Create a new commit
