Extend getPeerCertificateChain
Extend getPeerCertificateChain so that it uses the correct SSL
methods for Server and Client mode contexts, i.e.
SSL_get_peer_certificate as well as get_peer_cert_chain
when this is a server-mode context.
Tidy up error message logged on certificate verification
failure.
Always return "1" from verifyCallback; check result
of certificate verification by a call to
getPeerCertificateVerificationError() once the
TLS session is established.
