Andrew Rybchenko 460cb5684c sfxge: add prefast annotation to common code return types 
Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).

This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.
