Subject: Provide an EC method that uses homogeneous projective coordinates.

This makes use of EC_FIELD_ELEMENT to perform fixed width constant
time operations.

Addition and doubling of points makes use of the formulas from
"Complete addition formulas for prime order elliptic curves"
(https://eprint.iacr.org/2015/1060). These are complete and
operate in constant time.

Further work will continue in tree.
