Session resume broken switching contexts

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).

Allow DH_set0_key with only private key.

The pub_key field for DH isn't actually used in DH_compute_key at all.
(Note the peer public key is passed in as as BIGNUM.) It's mostly there
so the caller may extract it from DH_generate_key. It doesn't
particularly need to be present if filling in a DH from external
parameters.

The check in DH_set0_key conflicts with adding OpenSSL 1.1.0 to Node.
Their public API is a thin wrapper over the old OpenSSL one:
https://nodejs.org/api/crypto.html#crypto_class_diffiehellman

They have separate setPrivateKey and setPublicKey methods, so the public
key may be set last or not at all. In 1.0.2, either worked fine since
operations on DH objects generally didn't use the public key.  (Like
with OpenSSL, Node's setPublicKey method is also largely a no-op, but so
it goes.) In 1.1.0, DH_set0_key prevents create a private-key-only DH
object.

sha/asm/keccak1600-armv8.pl: fix return value buglet and ...

... script data load.

On related note an attempt was made to merge rotations with logical
operations. I mean as we know, ARM ISA has merged rotate-n-logical
instructions which can be used here. And they were used to improve
keccak1600-armv4 performance. But not here. Even though this approach
resulted in improvement on Cortex-A53 proportional to reduction of
amount of instructions, ~8%, it didn't exactly worked out on
non-Cortex cores. Presumably because they break merged instructions
to separate μ-ops, which results in higher *operations* count. X-Gene
and Denver went ~20% slower and Apple A7 - 40%. The optimization was
therefore dismissed.
