Add volatile qualifications to two blocks of inline asm to stop GCC from
eliminating them as dead code.
Both volatile and "memory" are used because of some concern that the compiler
may still cache values across the asm block without it, and because this was
such a painful debugging session that I wanted to ensure that it's never
repeated.

Always add a dynamically loaded ENGINE to list. Otherwise it can cause
problems when multiply loaded, especially if it adds new public key methods.
For all current engines we only want a single implementation anyway.

Add -engine_impl option to dgst which will use an implementation of
an algorithm from the supplied engine instead of just the default one.

The flag SSL_OP_MSIE_SSLV2_RSA_PADDING hasn't done anything since OpenSSL
0.9.7h but deleting it will break source compatibility with any software
that references it. Restore it but #define to zero.
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.

sha512.c: fullfull implicit API contract in SHA512_Transform.
SHA512_Transform was initially added rather as tribute to tradition
than for practucal reasons. But use was recently found in ssl/s3_cbc.c
and it turned to be problematic on platforms that don't tolerate
misasligned references to memory and lack assembly subroutine.

Move the IP, email and host checking fields from the public
X509_VERIFY_PARAM structure into an opaque X509_VERIFY_PARAM_ID
structure. By doing this the structure can be modified in future
without risk of breaking any applications.
In FIPS mode ssleay_rand_bytes is only used for PRNG seeding and is
performed in either a single threaded context (when the PRNG is first
initialised) or under a lock (reseeding). To avoid multiple locks disable
use of CRYPTO_LOCK_RAND in FIPS mode in ssleay_rand_bytes.

Additional "chain_cert" functions.
PR#3169
This patch, which currently applies successfully against master and
1_0_2, adds the following functions:
SSL_[CTX_]select_current_cert() - set the current certificate without
disturbing the existing structure.
SSL_[CTX_]get0_chain_certs() - get the current certificate's chain.
SSL_[CTX_]clear_chain_certs() - clear the current certificate's chain.
The patch also adds these functions to, and fixes some existing errors
in, SSL_CTX_add1_chain_cert.pod.
