Cycles: add "From Dupli" option for texture coordinate node. This gets the

Generated and UV coordinates from the duplicator of instance instead of the
object itself.

This was used in e.g. Big Buck Bunny for texturing instanced feathers with
a UV map on the bird. Many files changed, mainly to do some refactoring to
get rid of G.rendering global in duplilist code.
