delay/force overhaul.
* eval.c (promise_forced_s, promise_inprogress_s): New symbol variables. (me_delay): Change representation of promises so that the original delay form is stashed there for better reporting in the force function. Also, propagate the debug info from the second argument of the form to the entire form; otherwise it will inherit it from elsewhere. (force): Rewritten to follow new three-state representation to detect the recursive case and diagnose it. (eval_init): Register new symbol variables.
