[RFC] idle animation interface and implementation

[Pekka Paalanen]

Hi,

here is the patch set that integrates wscreensaver into the demo
compositor:
- interface implementation and surface type handling: screensaver
  surface only mapped during idle or lock screen
- automatic launch and kill
- automatic launch is opt-in, you need to enable it in your
  wayland-desktop-shell.ini
- works also with manual launch of wscreensaver
- separate timeouts for screen locking and animation
- all rendering stops on animation timeout
- supports multiple outputs with independent animations

The set also includes necessary bug fixes, and is built on top of my
for-krh-1 branch.

The patch set should be mergeable, except for the patch "HACK around
decorationless EGL user error". Constructive comments welcome.

(For those who didn't know, screen locking was available upstream
already on Nov 16th, 2011.)


Thanks.
