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.
