podlators 2.5.0 has switched to dying on POD syntax errors. This means
that a bunch of long-standing erroneous POD in the openssl documentation
now leads to fatal errors from pod2man, halting installation.

Unfortunately POD constraints mean that you have to sort numeric lists
in ascending order if they start with 1: you cannot do 1, 0, 2 even if
you want 1 to appear first. I've reshuffled such (alas, I wish there
were a better way but I don't know of one).

Now we set the current certificate to the one used by a server
there is no need to call ssl_get_server_send_cert which will
fail if we haven't sent a certificate yet.

Note: it was decided that after 0.9.8y it should be 0.9.8za then
0.9.8zb etc.

Fix the calculation that checks there is enough room in a record
after removing padding and optional explicit IV. (by Steve)

For AEAD remove the correct number of padding bytes (by Andy)
(cherry picked from commit be125aa5)

Kludge alert. This is arranged by passing padding length in unused
bits of SSL3_RECORD->type, so that orig_len can be reconstructed.

MD5 should use little endian order. Fortunately the only ciphersuite
affected is EXP-RC2-CBC-MD5 (TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5) which
is a rarely used export grade ciphersuite.

RISCs are picky and alignment granted by compiler for md_state can be
insufficient for SHA512.
(cherry picked from commit 36260233)

Break dependency on uint64_t. It's possible to declare bits as
unsigned int, because TLS packets are limited in size and 32-bit
value can't overflow.

branches it needs to be in a "gap".

We have to use EVP in FIPS mode so we can only partially mitigate
timing differences.

Make an extra call to HMAC_Update to hash additonal blocks
to cover any timing differences caused by removal of padding.

is in the fips module for fips capable builds.

This change updates the DTLS code to match the constant-time CBC
behaviour in the TLS.

The previous CBC patch was bugged in that there was a path through enc()
in s3_pkt.c/d1_pkt.c which didn't set orig_len. orig_len would be left
at the previous value which could suggest that the packet was a
sufficient length when it wasn't.

This patch makes the decoding of SSLv3 and TLS CBC records constant
time. Without this, a timing side-channel can be used to build a padding
oracle and mount Vaudenay's attack.

This patch also disables the stitched AESNI+SHA mode pending a similar
fix to that code.

In order to be easy to backport, this change is implemented in ssl/,
rather than as a generic AEAD mode. In the future this should be changed
around so that HMAC isn't in ssl/, but crypto/ as FIPS expects.

This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.
