Eventually, we'll want these macros to be functions, I think.
I'd personally like it if they all had the target_ops as the first
parameter, so that the target function can find the "target beneath"
and call its associated routine if needed. For instance:

  static void
  sol_thread_detach (struct target_ops *ops, char *args, int from_tty)
  {
    struct target_ops *beneath = find_target_beneath (ops);
  
    sol_thread_active = 0;
    inferior_ptid = pid_to_ptid (PIDGET (main_ph.ptid));
    unpush_target (ops);
    beneath->to_detach (beneath, args, from_tty);
  }
