Subject: [PATCH] Add the capability to auto-generate protocol code and headers

We'd like to drop all the generated files and keep just the xml files.

This is a step in that direction but we've been naming things irregularly
and some of our checked in generated code doesn't have an associated xml
yet, so this'll be a bit of a process.
