Reason for revert: This CL causes problems with the WebRTC-in-Chromium FYI bots. Presumably it needs to be done in several steps, where removed files are emptied instead of removed in the first step. Original issue's description: > TransportController refactoring. > > Getting rid of TransportProxy, and in its place adding a > TransportController class which will facilitate access to and manage > the lifetimes of Transports. These Transports will now be accessed > solely from the worker thread, simplifying their implementation. > > This refactoring also pulls Transport-related code out of BaseSession. > Which means that BaseChannels will now rely on the TransportController > interface to create channels, rather than BaseSession. > > Committed: https://crrev.com/47ee2f3b9f33e8938948c482c921d4e13a3acd83 > Cr-Commit-Position: refs/heads/master@{#10022} TBR=pthatcher@webrtc.org,deadbeef@webrtc.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.webrtc.org/1358413003 Cr-Commit-Position: refs/heads/master@{#10024}
