andrew@webrtc.org 7e5ddf5aa3 Restore behavior to FileWrapper::Read.
- Returning the number of bytes read was mistakenly removed in r1175 in
  an overzealous attempt to unify the interface.
- Now both Read and WriteText return the number of bytes/characters
  processed. Write unfortunately cannot be easily changed due to the
  inheritance from OutStream.
- Improve the interface comments.
