Change NATNUMP to return 1 for positive bignums; changes uses of
it and of CHECK_NATNUM appropriately, usually by checking for an
integer in an appropriate range.
Add array-dimension-limit and use it in #'make-vector,
#'make-string. Add array-total-size-limit, array-rank-limit while
we're at it, for the sake of any Common Lisp-oriented code that
uses these limits.
Rename check_int_range to check_integer_range, have it take
Lisp_Objects (and thus bignums) instead.
Remove bignum_butlast(), just set int_n to an appropriately large
integer if N is a bignum.
Accept bignums in check_sequence_range(), change the functions
that use check_sequence_range() appropriately.
Move the definition of NATNUMP() to number.h; document why it's a
reasonable name, contradicting an old comment.

* automated/lisp-tests.el:
* automated/lisp-tests.el (featurep):
* automated/lisp-tests.el (wrong-type-argument):
* automated/mule-tests.el (featurep):
Check for args-out-of-range errors instead of wrong-type-argument
errors in various places when code is handed a large bignum
instead of a fixnum.
Also check for the wrong-type-argument errors when giving the same
code a non-integer value.
