Re: nistp224 80-bit accuracy hack

curve25519 (http://cr.yp.to/ecdh.html) is new Diffie-Hellman software
with several advantages over nistp224. One of the advantages is that the
code is immune to compiler screwups: it's straight asm in *.s files.

Subsequent versions will include a simpler API, a non-x86 port, and
various speedups.
