2d64b51d20 Fix DTLS retransmission from previous session.
For DTLS we might need to retransmit messages from the previous session
so keep a copy of write context in DTLS retransmission buffers instead
of replacing it after sending CCS. CVE-2013-6450.

413cbfe68d 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.

e5420be6cd 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.

fceac0bc74 Fix compilation with -no-comp by adding some more #ifndef OPENSSL_NO_COMP
Some #include statements were not properly protected. This will go unnoted
on most systems as openssl/comp.h tends to be installed as a system header
file by default but may become visible when cross compiling.

52b8dad8ec Reorganize the data used for SSL ciphersuite pattern matching.
This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).

In some cases the ciphersuite list generated from a given string is
affected by this change.  I hope this is just in those cases where the
previous behaviour did not make sense.
