Remove the apply limit wrt the number of arguments

[Mario Domenech Goulart]

If feasible, naturally.

Maybe we'll find the time to do it for 4.11, otherwise 5 will have to be our target

I think the argvector fix has removed the limit for all intents & purposes:

(use srfi-1)
(print (apply + (make-list 100000 1)))

(use-for-syntax srfi-1)
(define-syntax foo
  (ir-macro-transformer
    (lambda (e r c)
      `(print (+ . ,(make-list (cadr e) 1))))))
(foo 100000)

Compiling and running this prints 100000 twice. Interpreting it does the same.

The only case where this could still fail is a procedure which receives a huge number of arguments, and right at the start the stack is just full, so a reclaim is needed. Then the argvector will be saved on the temporary stack, and it will not fit. So a resize of the temporary stack would be required (which can be done in the C_save_and_reclaim[_args] functions easily).

I'll have to think of a good way to test this...

Patch submitted for CHICKEN 5. Probably not important enough to fix for CHICKEN 4.
