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.

Gets rid of this;

defined(@array) is deprecated at ../util/mkerr.pl line 792.
        (Maybe you should just omit the defined()?)

to keep up to date with releases.  Reported because

o_time.h was removed in commit ff49a944

, which breaks "make update"
unless mkdir.pl is updated accordingly.

Fix typo that stopped SSL_CTX_get_{first,next}_certificate from working.

When looking for an extension we need to set the last found
position to -1 to properly search all extensions.

PR#3309.

Keep copy of any host, path and port values allocated by
OCSP_parse_url and free as necessary.

Treat a zero length passed to ssleay_rand_add a no op: the existing logic
zeroes the md value which is very bad. OpenSSL itself never does this
internally and the actual call doesn't make sense as it would be passing
zero bytes of entropy.
