cproj, cprojf, cprojl - project into Riemann Sphere

Link with -lm.
This function projects a point in the plane onto the surface of a
Riemann Sphere, the one-point compactification of the complex plane.
Each finite point z projects to z itself.
Every complex infinite value is projected to a single infinite value,
namely to positive infinity on the real axis.
The glibc implementation is broken and does something entirely different.
