Initialize pointers in param id by the book (explicit NULL assignment,
rather than just memset 0).

In x509_verify_param_zero() set peername to NULL after freeing it.

In x509_vfy.c's internal check_hosts(), avoid potential leak of
possibly already non-NULL peername.  This is only set when a check
succeeds, so don't need to do this repeatedly in the loop.

Commit f0348c84

 introduced a problem with session resumption. The
version for the session is fixed when the session is created. By moving
the creation of the session earlier in the process the version is fixed
*before* version negotiation has completed when processing the ServerHello
on the client side. This fix updates the session version after version neg
has completed.

Builds using no-tlsext in 1.0.0 and 0.9.8 are broken. This commit fixes the
issue. The same commit is applied to 1.0.1 and 1.0.2 branches for code
consistency. However this commit will not fix no-tlsext in those branches
which have always been broken for other reasons. The commit is not applied
to master at all, because no-tlsext has been completely removed from that
branch.

A DTLS client will abort a handshake if the server attempts to renew the
session ticket. This is caused by a state machine discrepancy between DTLS
and TLS discovered during the state machine rewrite work.

The bug can be demonstrated as follows:

Start a DTLS s_server instance:
openssl s_server -dtls

Start a client and obtain a session but no ticket:
openssl s_client -dtls -sess_out session.pem -no_ticket

Now start a client reusing the session, but allow a ticket:
openssl s_client -dtls -sess_in session.pem

The client will abort the handshake.
