DTLSv1_handle_timeout() handles any timeout events which have become pending on a DTLS or QUIC SSL
       object.

       Use DTLSv1_get_timeout(3) or SSL_get_event_timeout(3) to determine when to call DTLSv1_handle_timeout().

       This function is only applicable to DTLS or QUIC SSL objects. It returns 0 if called on any other kind of
       SSL object.

       SSL_handle_events(3) supersedes all use cases for this function and may be used instead of it.

       DTLSv1_handle_timeout - handle a pending timeout event for a DTLS or QUIC SSL object

       Returns 1 if there was a pending timeout event and it was handled successfully.

       Returns 0 if there was no pending timeout event, or if the SSL object is not a DTLS or QUIC object.

       Returns -1 if there was a pending timeout event but it could not be handled successfully.
