bugfix: n-ary arith functions must check single arg.

We are allowing calls like (* "a") and (+ "a")
without diagnosing that the argument isn't of a valid
type. Note that (max "a") is fine beacause min and
max use the less function; they are not strictly numeric.

* lib.c (nary_op): Beef up function with additional argument
for type checking the unary case.
(unary_num, unary_arith, unary_int): New static functions.
(plusv, mulv, logandv, logiorv): Use new nary_op interface.
(gtv, ltv, gev, lev, numeqv, numneq): Check the
first number.

* lib.c (nary_op): Declaration updated.
