//       Class : BioPtr
// Description : A wrapper around an OpenSSL BIO object to make a
//               reference-counting pointer to it.  It appears that
//               the OpenSSL library already uses reference counts on
//               these things internally, but the interface doesn't
//               appear to be public; so we might as well wrap the
//               whole thing at the high level.
