This gives a 10 to 20% speedup on a Core i7. In addition, the CurveGFp no longer contains a Barrett reducer, saving 3 BigInts worth of memory. Add a #if'ed out alternative to point multiplication using the Montgomery ladder technique. It runs in (more or less) constant time, but rather significantly slower than the 4 bit window technique currently used. Tweak the window sizes to match the theoretical optimums.

The DL private keys instead have on constructor for this; if the x value is zero, then a new random key is created. For consistency, do this with ECC as well. ECDH actually didn't have one of these constructors, forcing you to either load from PKCS #8 or else use a random key. Rename EC_Domain_Params to EC_Group, with a typedef for compatability.

Update callers. This showed several cases where check_invaraints was being called multiple times, for instance when decoding a point with OS2ECP, check_invaraints was called; many callers of OS2ECP would then call check_invaraints again on the same object.

Define operator==() in terms of the affine coordinates. Rewrite tests that assumed access to the Jacobian coodinates in terms of the affine coordinates. This change allows for using arbitrary coordinate systems in PointGFp, as long as it can convert to the normal affine coordinates (which are what is used by all ECC algorithms implemented currently, and probably all interesting ECC algorithms in general).
