please add comments to this file describing what the different messages are used
for

Comments are stripped by the tool that creates these buffers. Again, I can ask
the folks who wrote the tool to look into not removing them.

why are already-deprecated fields being added?

[rkc, 2014/07/29 00:33:36]

In the RPC code (which will come in another CL), we have a TODO to remove all
the deprecated fields and change our client code to match.
