This reverts commit 591b2ab82ead157b5f5a85d5082bd15fe8c51809. Reason for revert: Breaks downstream project Original change's description: > Wires up WebrtcKeyValueBasedConfig in media engines. > > This replaces field_trial:: -based functions from system_wrappers. > Field trials are still used as fallback, but injectable trials are now > possible. > > Bug: webrtc:11926 > Change-Id: I70f28c4fbabf6d9e55052342000e38612b46682c > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/174261 > Reviewed-by: Per Kjellander <perkj@webrtc.org> > Reviewed-by: Kári Helgason <kthelgason@webrtc.org> > Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> > Reviewed-by: Stefan Holmer <stefan@webrtc.org> > Reviewed-by: Sebastian Jansson <srte@webrtc.org> > Commit-Queue: Erik Språng <sprang@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#32129} TBR=mbonadei@webrtc.org,kthelgason@webrtc.org,sprang@webrtc.org,stefan@webrtc.org,srte@webrtc.org,perkj@webrtc.org Change-Id: I3e169149a8b787aa6366bb357abb71794534c63a No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:11926 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/184507 Reviewed-by: Artem Titov <titovartem@webrtc.org> Commit-Queue: Artem Titov <titovartem@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32132}
