Mark functions with override instead of virtual. Add explicit non-trivial constructors/assign operators/destructors. Define them in .cc files instead of inlining use auto* instead of auto when deduced type is raw pointer Bug: webrtc:163 Change-Id: I4d8a05d6a64fcc2ca16d02c5fcf9488fda832a6d Reviewed-on: https://webrtc-review.googlesource.com/48781 Commit-Queue: Danil Chapovalov <danilchap@webrtc.org> Reviewed-by: Karl Wiberg <kwiberg@webrtc.org> Cr-Commit-Position: refs/heads/master@{#21927}
