openssl/ssl/ssltest.c
Dr. Stephen Henson f9784baf0e Fix comments, add new test. 
Fix comments in ssltest.c: return value of 0 now means extension is
omitted and add_cb is not called for servers if the corresponding
extension is absent in ClientHello.

Test add_cb is not called if extension is not received.
