defstruct: diagnose built-in type being redefined.
* eval.c (eval_init): Register built-in-type-p intrinsic. * lib.c (buitin_type_p): Rename to built_in_type_p since the word built-in is hyphenated. The function also tests whether the argument is a COBJ class. (cobj_class_exists): Function removed. * stdlib/doc-syms.tl: Updated. * stdlib/struct.tl (defstruct): Add built-in-type-p check. * struct.c (make_struct_type): Call only built_in_type_p; cobj_class_exists is gone. * txr.1: Document built-in-type-p.
