	Bug 556433 – assume direction = out for int * parameters

	* giscanner/ast.py: define a list of types for which, if passed as
	reference, we assume a default direction of 'out'
	* giscanner/transformer.py: if a type has type pointer to one of the
	previously defined types, and no direction is set, assume out.
	* tests/scanner/drawable.[ch]: added tests for guessed direction=out
