qapi: Eliminate accidental global frontend state
The frontend can't be run more than once due to its global state. A future commit will want to do that. The only global frontend state remaining is accidental: QAPISchemaParser.__init__()'s parameter previously_included=[]. Python evaluates the default once, at definition time. Any modifications to it are visible in subsequent calls. Well-known Python trap. Change the default to None and replace it by the real default in the function body. Use the opportunity to convert previously_included to a set.
