    guard against accidental regressions regarding obj
    
    enum gethdr_e and VCL_HTTP have a 1:1 relation except for HDR_OBJ which
    does not have a corresponding VCL_HTTP pointer.
    
    As I am about to use a "reverse VRT_selecthttp()" to get from VCL_HTTP
    to enum gethdr_e, I would want to guard against accidental introduction
    of a regression.
