curve25519-donna: Curve25519 elliptic curve, public key function

Derived from public domain C code by Daniel J. Bernstein [email protected]

More information about curve25519 can be found here http://cr.yp.to/ecdh.html

djb's sample implementation of curve25519 is written in a special assembly language called qhasm and uses the floating point registers.

This is, almost, a clean room reimplementation from the curve25519 paper. It uses many of the tricks described therein. Only the crecip function is taken from the sample implementation.
