Keeping it in error.py will create some cyclic import problems when we add types to the QAPISchemaParser. Callers don't need to know the details of QAPIParseError unless they are parsing or dealing directly with the parser, so this won't create any harsh new requirements for callers in the general case. Update error.py with a little docstring that gives a nod to where the error may now be found.
