New structure type SESS_CERT used instead of CERT inside SSL_SESSION.

Browse Source 
While modifying the sources, I found some inconsistencies on the use of
s->cert vs. s->session->sess_cert; I don't know if those could
really have caused problems, but possibly this is a proper bug-fix
and not just a clean-up.

Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
does not influence s as it used to.
Projected further changes:
In order to clean up things more thoroughly, inside SSL_SESSION
we should not use CERT any longer, but a new structure SESS_CERT
that holds per-session data, and CERT should hold only those
values that can have meaningful defaults in an SSL_CTX.
we don't use CERT any longer, but a new structure SESS_CERT
that holds per-session data (if available); currently, this is
the peer's certificate chain and, for clients, the server's certificate
and temporary key. CERT holds only those values that can have
meaningful defaults in an SSL_CTX.
[Bodo Moeller]
*) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
