    Workaround gjs single-include issue
    
    gjs features single-include guards for the headers in gjs/ with
    gjs/gjs-module.h being the only header you are supposed to include.
    
    Unfortunately, the headers in gi/ (which do not appear to have their own
    master include file) individually include files from gjs/.
    
    We can workaround the issue by first #include <gjs/gjs-module.h> which
    will skip the single-include guard on the files the second time they get
    included (from the headers in gi/).
