    Fix definition of CamelProvider.url_equal().
    
    Functions of type GCompareFunc are supposed to return -1/0/1 as in
    strcmp().  CamelProvider.url_equal() should instead be a GEqualFunc
    since it returns TRUE or FALSE.
    
    Function signatures are identical except for the return type, but
    gboolean is a type of gint so no changes required for providers.
