qapi: skip redundant includes
The purpose of this change is to help create a json file containing
common definitions; each bit of generated C code must be emitted
only one time.
A second history global to all QAPISchema instances has been added
to detect when a file is included more than one time and skip these
includes.
It does not act as a stack and the changes made to it by the
__init__ function are propagated back to the caller so it's really
a global state.
