When looking for the issuer of a certificate, if current candidate is
expired, continue looking. Only return an expired certificate if no valid
certificates are found.

subjectAltName field. The Name Contraint example in x509v3_config(5) even use IP
as an example:
nameConstraints=permitted;IP:192.168.0.0/255.255.0.0
However, until now, the verify code for IP name contraints did not exist. Any
check with a IP Address Name Constraint results in a "unsupported name constraint
type" error.
This patch implements support for IP Address Name Constraint (v4 and v6). This code
validaded correcly certificates with multiple IPv4/IPv6 address checking against
a CA certificate with these constraints:
permitted;IP.1=10.9.0.0/255.255.0.0
permitted;IP.2=10.48.0.0/255.255.0.0
permitted;IP.3=10.148.0.0/255.255.0.0
permitted;IP.4=fdc8:123f:e31f::/ffff:ffff:ffff::

"Teaser" means that it's not integrated yet and purpose of this
commit is primarily informational, to exhibit design choices,
such as how to handle alignment and endianness. In other words
it's proof-of-concept code that EVP module will build upon.
If the key type does not match any CMS recipient type return
an error instead of using a random key (MMA mitigation). This
does not leak any useful information to an attacker.

This patch resolves RT ticket #2608.
Thanks to Robert Dugal for originally spotting this, and to David
Ramos for noticing that the ball had been dropped.

The lazy-initialisation of BN_MONT_CTX was serialising all threads, as
noted by Daniel Sands and co at Sandia. This was to handle the case that
2 or more threads race to lazy-init the same context, but stunted all
scalability in the case where 2 or more threads are doing unrelated
things! We favour the latter case by punishing the former. The init work
gets done by each thread that finds the context to be uninitialised, and
we then lock the "set" logic after that work is done - the winning
thread's work gets used, the losing threads throw away what they've done.

Even though the meat of dso_vms.c is compiled out on non-VMS builds,
the (pre-)compiler still traverses some of the macro handling. This
trips up at least one non-VMS build configuration, so this commit
makes the skip-VMS case more robust.

It's not clear whether this inconsistency could lead to an actual
computation error, but it involved a BIGNUM being passed around the
montgomery logic in an inconsistent state. This was found using flags
-DBN_DEBUG -DBN_DEBUG_RAND, and working backwards from this assertion
in 'ectest';
ectest: bn_mul.c:960: BN_mul: Assertion `(_bnum2->top == 0) ||
(_bnum2->d[_bnum2->top - 1] != 0)' failed
