x86_64 assembly pack: "optimize" for Knights Landing.

"Optimize" is in quotes because it's rather a "salvage operation"
for now. Idea is to identify processor capability flags that
drive Knights Landing to suboptimial code paths and mask them.
Two flags were identified, XSAVE and ADCX/ADOX. Former affects
choice of AES-NI code path specific for Silvermont (Knights Landing
is of Silvermont "ancestry"). And 64-bit ADCX/ADOX instructions are
effectively mishandled at decode time. In both cases we are looking
at ~2x improvement.

Hardware used for benchmarking courtesy of Atos, experiments run by
Romain Dolbeau <romain.dolbeau@atos.net>. Kudos!

This is minimalistic backpoint of 64d92d74985ebb3d0be58a9718f9e080a14a8e7f

The intention of the removed code was to check if the previous operation

Fix undefined behaviour in e_aes_cbc_hmac_sha256.c and e_aes_cbc_hmac_sha1.c

In TLS mode of operation the padding value "pad" is obtained along with the
maximum possible padding value "maxpad". If pad > maxpad then the data is
invalid. However we must continue anyway because this is constant time code.

We calculate the payload length like this:

    inp_len = len - (SHA_DIGEST_LENGTH + pad + 1);

However if pad is invalid then inp_len ends up -ve (actually large +ve
because it is a size_t).

Later we do this:

    /* verify HMAC */
    out += inp_len;
    len -= inp_len;

This ends up with "out" pointing before the buffer which is undefined
behaviour. Next we calculate "p" like this:

    unsigned char *p =
        out + len - 1 - maxpad - SHA256_DIGEST_LENGTH;

Because of the "out + len" term the -ve inp_len value is cancelled out
so "p" points to valid memory (although technically the pointer arithmetic
is undefined behaviour again).

We only ever then dereference "p" and never "out" directly so there is
never an invalid read based on the bad pointer - so there is no security
issue.

This commit fixes the undefined behaviour by ensuring we use maxpad in
place of pad, if the supplied pad is invalid.

With thanks to Brian Carpenter for reporting this issue.

Copy custom extension flags in a call to SSL_set_SSL_CTX()

The function SSL_set_SSL_CTX() can be used to swap the SSL_CTX used for
a connection as part of an SNI callback. One result of this is that the
s->cert structure is replaced. However this structure contains information
about any custom extensions that have been loaded. In particular flags are
set indicating whether a particular extension has been received in the
ClientHello. By replacing the s->cert structure we lose the custom
extension flag values, and it appears as if a client has not sent those
extensions.

SSL_set_SSL_CTX() should copy any flags for custom extensions that appear
in both the old and the new cert structure.

aes/asm/bsaes-armv7.pl: relax stack alignment requirement.

Even though Apple refers to Procedure Call Standard for ARM Architecture
(AAPCS), they apparently adhere to custom version that doesn't follow
stack alignment constraints in the said standard. [Why or why? If it's
vendor lock-in thing, then it would be like worst spot ever.] And since
bsaes-armv7 relied on standard alignment, it became problematic to
execute the code on iOS.

Fix decoding of ASN.1 LONG and ZLONG items

LONG and ZLONG items (which are OpenSSL private special cases of
ASN1_INTEGER) are encoded into DER with padding if the leading octet
has the high bit set, where the padding can be 0x00 (for positive
numbers) or 0xff (for negative ones).

When decoding DER to LONG or ZLONG, the padding wasn't taken in
account at all, which means that if the encoded size with padding
is one byte more than the size of long, decoding fails. This change
fixes that issue.

Fix DTLSv1_listen() sequence numbers

DTLSv1_listen() is stateless. We never increment the record read sequence
while listening, and we reflect the incoming record's sequence number in our
write sequence.

The logic for doing the write sequence reflection was *after* we had
finished processing the incoming ClientHello and before we write the
ServerHello. In the normal course of events this is fine. However if we
need to write an early alert during ClientHello processing (e.g. no shared
cipher), then we haven't done the write sequence reflection yet. This means
the alert gets written with the wrong sequence number (it will just be set
to whatever value we left it in the last time we wrote something). If the
sequence number is less than expected then the client will believe that the
incoming alert is a retransmit and will therefore drop it, causing the
client to hang waiting for a response from the server.

Fixes #2886
