New feature: user-defined math.

Most of the library now accepts struct objects as
arguments, relying on them to implement methods.

of string lit.
(arith_init): Initialize new symbol variables. Replace
existing intern calls in function registrations with
references to some of these symbol variables.

* txr.1: Documented.
