This will make further changes to these classes safer by ensuring that the compile breaks if the base class changes and not all overrides are fixed. This also highlighted a number of unused functions which I've removed. -- This is was reviewed in https://webrtc-codereview.appspot.com/19309004/, but -- a new cl was needed to resolve a small conflict before committing. BUG=none TEST=none TBR=pbos@webrtc.org Review URL: https://webrtc-codereview.appspot.com/22359004 git-svn-id: http://webrtc.googlecode.com/svn/trunk@7162 4adac7df-926f-26a2-2b94-8c16560cd09d
