The IPC channel names and event names used by the service process now append the version string so that a browser with the same version only can talk to it.
In addition, the service process writes its version into shared memory (the name of this shared mem does not use a version) and also listens on a shutdown event. This can be used by a newer service process to shutdown an older version when it starts.
BUG=None
TEST=Unittests, with an existing service process running, let chrome autoupdate and then run the service process again. It should kill the old one.
