Reason for revert: The openmax_dl include change breaks downstream projects. Original issue's description: > Add check_deps rules in DEPS files. > > Add fine-grained check_deps rules for all of WebRTC. > This will help both maintaining sane dependencies and provides a way > to visualize dependency graphs using the buildtools/checkdeps/graphdeps.py script. > > Example: > buildtools/checkdeps/graphdeps.py --root=. --format=png \ > --out=./webrtc.png --incl='^webrtc/modules/bitrate_controller->' \ > --excl='chromium|base|external|testing|webrtc/test|\.h$|\.cc$' > > will produce a neat webrtc.png image showcasing the dependencies > (according to the DEPS file) for the bitrate_controller module. > Some dependencies are filtered out for readability. > > BUG=webrtc:5623 > TESTED=Passing runs using: > buildtools/checkdeps/checkdeps.py --root=. talk > buildtools/checkdeps/checkdeps.py --root=. webrtc > > R=tommi@webrtc.org > > Committed: https://crrev.com/086f851b7b9b4bcbd4fe507c3bf83b760bd7f4d9 > Cr-Commit-Position: refs/heads/master@{#12008} TBR=tommi@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
