Move the easing functions to their own file Instead of having the easing functions be dependent of ClutterAlpha, and static to the clutter-alpha.c source file, we should make them generic and move them to their own internal header and source files. This will allow to re-use them in the near future.

easing: Add utility functions We end up copying the same array-of-modes-and-functions code in various places, so it's better to factor it out.
