    Use glib-mkenum's prefixes to avoid sed
    
    GLib's enumeration type generation tool has two command line option that
    allow us to specify the identifier and symbol prefixes. This allows us
    to avoid multiple passes of sed and speed up the generation pass.
    
    The identifier and symbol prefix options were introduced in GLib 2.32,
    so we will need to bump the required version.
