  AHTCallback_bridge
  this function acts as a bridge between Xt and libwww. From the Xt
  point of view, this function is the callback handler whenever there's
  any activity on the sockets associated with the active requests. From
  the libwww point of view, this is the function that takes the initiative
  to invoke the callback function associated with an active request,
  whenever there's an activity in the socket associated to it.
  In this latter  aspect, this function is similar to the library's
  own __DoCallback()  function.
  Upon activation, the function looks up the request associated with the
  active socket and then looks up the cbf associated with that request.
  Upon completion of the execution of the request's cbf, it verifies
  the state of the request and, if it's an asynchronous request, deletes
  the memory allocated to it.
