This is the first part of changes to implement the STEED proposal as
described at http://g10code.com/steed.html .  The idea for X.509 is
not to use plain self-signed certificates but certificates signed by a
dummy CA (i.e. one for which the private key is known).  Having a
single CA as an indication for the use of STEED might help other X.509
implementations to implement STEED.
