define-option-struct: use multiple inheritance
* share/txr/stdlib/getopts.tl (sys:option-base): New struct
type, holding the boiler-plate methods and slots that were
generated into the user-defined struct by
define-option-struct.
(define-option-struct): Inject the required properties by
inheritance from sys:option-base, greatly reducing code bloat
in the macro. The slot hash and opt-desc-list static slots
have to be redefined in the derived structure so that type has
its own instance of them.
