…specified Allows clients to distinguish between a server that returns us an error we recognize, and errors that are generic HTTP (due to an intervening proxy)
Will allow clients to determine when the configuration is bad.
Omit glog prefix when v < 2, show multiline errors for configuration problems, add new generic messages for server errors that hide some complexity that is not relevant for users.

I had the original two cases and removed them. I can reduce to if, although I expect cases to be added here for other conditions eventually.

On v < 2, we write to os.Stderr and exit 1 instead of calling glog.Fatalf
