This CL renames the main filter in AEC3 to have the more accurate name refined filter. The CL consists of 3 main initial patch sets, designed to simplify the review: 1) Replaces "main" with "refined" and adds a fall-back functionality to support the old filter naming. 2) Renames the files according to the new naming. 3) Performs a "git cl format" Bug: webrtc:8671 Change-Id: Ifd0aab34e291736a2250e0986348404618630b1d Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/170825 Reviewed-by: Sam Zackrisson <saza@webrtc.org> Commit-Queue: Per Åhgren <peah@webrtc.org> Cr-Commit-Position: refs/heads/master@{#30843}
