2aec073a52 ssl/*: remove SSL3_RECORD->orig_len to restore binary compatibility.
Kludge alert. This is arranged by passing padding length in unused
bits of SSL3_RECORD->type, so that orig_len can be reconstructed.

4af91ec072 ssl/s3_cbc.c: md_state alignment portability fix.
RISCs are picky and alignment granted by compiler for md_state can be
insufficient for SHA512.

6b2a843970 ssl/s3_cbc.c: uint64_t portability fix.
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.

8109e8305b Add ordinal for CRYPTO_memcmp: since this will affect multiple

c4e6fb1524 Timing fix mitigation for FIPS mode.
We have to use EVP in FIPS mode so we can only partially mitigate
timing differences.

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

e33ac0e71d Update DTLS code to match CBC decoding in TLS.
This change updates the DTLS code to match the constant-time CBC
behaviour in the TLS.

93cab6b319 Don't crash when processing a zero-length, TLS >= 1.1 record.
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.

2acc020b77 Make CBC decoding constant time.
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.

7c770d572a Add and use a constant-time memcmp.
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.
