[PATCH v4 19/19] scripts: apibuild: add parsing variable's comments
scripts/apibuild.py did not consider exporting external variable's
comments into the XML API. This commits fixes that.
Noe that the way that CParser is designed, it is currently possible to
lose a parsed comment when parsing other fields as self.comment in
several places. I've added a comment to highlight this.
