Libfunc for creating an EC point from its coordinates x and y.
If (x, y) is not on the curve, nothing is returned.
Libfunc for checking whether the given EcPoint is the zero point.
Libfunc for unwrapping the x,y values of an EC point.
Libfunc for creating an EC point from its x coordinate.
If there exists y such that (x, y) is on the curve, either (x, y) or (x, -y) (both
constitute valid points on the curve) is returned.
Otherwise, nothing is returned.
An EC point is a pair (x,y) on the curve.
Libfunc for initializing an EC state from an EC point.
Libfunc for applying the EC op builtin: given an EC state S, a scalar M and an EC point Q,
computes a new EC state S + M * Q.
Libfunc for initializing an EC state from an EC point.
Libfunc for initializing an EC state from an EC point.
An EC state is an EC point and a pointer to a random EC point shift.
Libfunc for unwrapping the x,y values of an EC point.
Libfunc for returning the zero point (the point at infinity).
