* XXX: The following accessors demonstrate the amount of care and thought that

* these functions return what was passed in. Correct memory management is left
* as an exercise for the reader... Unfortunately, careful consumers like
* openssl-ruby assume this behavior, so we're stuck with this insanity. The
* cherry on top is the TS_VERIFY_CTS_set_certs() [sic!] function that made it
* into the public API.
