Extending intrinsic functions to go up to 7 arguments.

Adding wrapper for mktime.

* eval.c (apply): Handle function codes N5 through N7.
(eval_init): Register make_time as intrinsic.

* lib.c (auto_k): New keyword symbol variable.
(equal, generic_funcall): Handle N5-N7.
(func_n5, func_n6, func_n7, func_n5v, func_n6v, func_n7v): New
functions.
(obj_init): Initialize auto_k.
(make_time): New function.

* lib.h (functype_t): New enum members: N5, N6, N7.
(struct func): New members: n5, n6, n7, n5v, n6v, n7v.
(auto_k, func_n5, func_n6, func_n7, func_n5v, func_n6v, func_n7v,
make_time): Declared.
