[PATCH weston v3 09/17] compositor: rename scaler to viewport(er)

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

Since the interface is now called wp_viewport, rename functions from
"scaler" to "viewporter" as well.

scaler_surface_to_buffer() is renamed to viewport_surface_to_buffer()
because it is more about viewport than viewporter.
