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.

sha/asm/sha256-armv4.pl: add ARMv8 code path.

PR: 3338

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

Specify -f is for compilation flags. Add -d to synopsis section.

Closes #77.

Fix eckey_priv_encode to return an error on failure of i2d_ECPrivateKey.

There are certainly many more constifiable strings in the various
interfaces, which I hope to get to eventually.
