CCM does not support streaming: An additional call to (EVP_...)Update must
precede each call to Update to pass the total message length. The generic
Update_loop calls Update one time such that in case of CCM only the total
message length is passed. No encryption/decryption measured.

When an SSL's context is swtiched from a ticket-enabled context to
a ticket-disabled context in the servername callback, no session-id
is generated, so the session can't be resumed.

If a servername callback changes the SSL_OP_NO_TICKET option, check
to see if it's changed to disable, and whether a session ticket is
expected (i.e. the client indicated ticket support and the SSL had
tickets enabled at the time), and whether we already have a previous
session (i.e. s->hit is set).

In this case, clear the ticket-expected flag, remove any ticket data
and generate a session-id in the session.

If the SSL hit (resumed) and switched to a ticket-disabled context,
assume that the resumption was via session-id, and don't bother to
update the session.

Before this fix, the updated unit-tests in 06-sni-ticket.conf would
fail test #4 (server1 = SNI, server2 = no SNI).

This allows the caller to guarantee that there is sufficient space for a

The expansion ratio when reallocating the array is reduced to 1.5 rather than 2.

Change bounds testing to use a single size rather than both INT_MAX and
