This CL renames the shadow filter in AEC3 to have the more accurate name coarse filter. The CL consists of 3 main initial patch sets, designed to simplify the review: 1) Replaces "shadow" with "coarse" 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: I28d6041d0d34e85f8f8048d004b44a1a5f07bb07 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/170981 Commit-Queue: Per Åhgren <peah@webrtc.org> Reviewed-by: Sam Zackrisson <saza@webrtc.org> Cr-Commit-Position: refs/heads/master@{#30846}
