    reftests: Fix building on Visual Studio
    
    We need to mark the prototypes in the headers so that they get exported
    properly from the reftest DLLs that we build, so that the reftest DLLs
    and program will link properly.  Include gtk-reftest.h in
    reftest-snapshot.c so that the compiler picks up the export directives
    as needed.
