Pull the parsing helper functions out of the Triple interface entirely.

They're private static methods but we can just make them static
functions in the implementation. It makes the implementations a touch
more wordy, but takes another chunk out of the header file.

Also, take the opportunity to switch the names to the new coding
conventions.

No functionality changed here.
