b6db386ffd Change internals of the EC library so that the functions
EC_GROUP_{set_generator,get_generator,get_order,get_cofactor} are
implemented directly in crypto/ec/ec_lib.c and not dispatched to
methods.

Also fix EC_GROUP_copy to copy the NID.

af28dd6c75 Fix bugs and typos.
Add some WTLS curves.
New function EC_GROUP_check() (this will probably
be implemented differently soon).

8a2908a24a Since they aren't implemented yet, EC_GFp_{recp,nist}_method() need to
be "#if 0"'d, or they will (re)appear as existing functions in
util/libeay.num.

4f69172d25 Completely remove mont2 stuff.
It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).

3837491174 Add functions EC_POINT_mul and EC_GROUP_precompute.
The latter does nothing for now, but its existence means
that applications can request precomputation when appropriate.

7e0c5264e7 Elliptic curves over GF(p), new BIGNUM functions, Montgomery re-implementation.
These new files will not be included literally in OpenSSL, but I intend
to integrate most of their contents.  Most file names will change,
and when the integration is done, the superfluous files will be deleted.
