Add a pointer type to traceeval_data, as this can be used as a generic
pointer type. This may even obsolete the dynamic type.

Also, add a const char * "cstring" type. There's times where the key and
value data needs to be assigned to a const char *string, and without
having an option of that type, the compiler complains about losing the
const.
