If a NewSessionTicket is received by a multi-threaded client when
attempting to reuse a previous ticket then a race condition can occur
potentially leading to a double free of the ticket data.
CVE-2015-1791
This also fixes RT#3808 where a session ID is changed for a session already
in the client session cache. Since the session ID is the key to the cache
this breaks the cache access.

Kludge alert. This is arranged by passing padding length in unused
bits of SSL3_RECORD->type, so that orig_len can be reconstructed.
(cherry picked from commit 413cbfe68d)
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.
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.

work in SSLv3: initial handshake has no extensions but includes MCSV, if
server indicates RI support then renegotiation handshakes include RI.
NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.
Change mismatch alerts to handshake_failure as required by spec.
Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.
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.
1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.
functions and macros.
This change has associated tags: LEVITTE_before_const and
LEVITTE_after_const. Those will be removed when this change has been
properly reviewed.
