Changes since 1.21: +4 -3 lines 

Allow key exchange with RSA signature authentication to work with
Cisco IOS and other initiators that only send their certs in response
to CERT_REQUEST.

With input and help from cloder@, Stuart Henderson, mpf@, and several
others who did lots of testing - thanks to all.
