    gsettingsbackend.h: pretend to be gio.h
    
    Since #include <gsettingsbackend.h> is a perfectly valid thing for
    applications to do, and since we want to include gio headers from
    gsettingsbackend.h, we need to effectively disable the #error we would
    get from those headers (because we're not coming via gio.h).
    
    We don't want to #include <gio/gio.h> here because this would cause
    needless rebuilding of GSettingsBackend, GSettings,
    GDelayedSettingsBackend, etc... every time someone changed anything in
    any public header.
