I still need to revive the original CL, but right now I'm interested in
giving every EC_GROUP an order_mont and having different ownership of
that field between built-in and custom groups is kind of a nuisance. If
I'm going to do that anyway, better to avoid computing the entire
EC_GROUP in one go.
I'm using some manual locking rather than CRYPTO_once here so that it
behaves well in the face of malloc errors. Not that we especially care,
but it was easy to do.
This speeds up our ECDH benchmark a bit which otherwise must construct the
EC_GROUP each time (matching real world usage).
Before:
Did 7619 ECDH P-224 operations in 1003190us (7594.8 ops/sec)
Did 7518 ECDH P-256 operations in 1060844us (7086.8 ops/sec)
Did 572 ECDH P-384 operations in 1055878us (541.7 ops/sec)
Did 264 ECDH P-521 operations in 1062375us (248.5 ops/sec)
After:
Did 8415 ECDH P-224 operations in 1066695us (7888.9 ops/sec)
Did 7952 ECDH P-256 operations in 1022819us (7774.6 ops/sec)
Did 572 ECDH P-384 operations in 1055817us (541.8 ops/sec)
Did 264 ECDH P-521 operations in 1060008us (249.1 ops/sec)

We don't currently have test coverage for the order_mont bits (or lack
thereof) for custom curves.

It's confusing to have both mont and mont_data on EC_GROUP. The
documentation was also wrong.

This avoids depending the FIPS module on crypto/bytestring and moves
ECDSA_SIG_{new,free} into the module.

The names in the P-224 code collided with the P-256 code and thus many
of the functions and constants in the P-224 code have been prefixed.
