Bug #815 - Split up request, allocation, and paint box

	* clutter/clutter-actor.[ch]: Rework the size allocation,
	request and paint area. Now ::request_coords() is called
	::allocate(), and ::query_coords() has been split into
	::get_preferred_width() and ::get_preferred_height(). See
	the documentation and the layout test on how to implement
	a container and layout manager with the new API. (#915,
	based on a patch by Havoc Pennington, Lucas Rocha and Johan
	Bilien)

	* clutter/clutter-clone-texture.c: Port CloneTexture to
	the new size negotiation API; it just means forwarding
	the requests to the parent texture.

	* clutter/clutter-deprecated.h: Add deprecated and replaced
	API.

	* clutter/clutter-entry.c: Port Entry to the new size
	negotiation API.

	* clutter/clutter-group.c: Port Group to the new size
	negotiation API; the semantics of the Group actor do not
	change.

	* clutter/clutter-label.c: Port Label to the new size
	negotiation API, and vastly simplify the code.

	* clutter/clutter-main.[ch]: Add API for executing a
	relayout when needed.

	* clutter/clutter-private.h: Add new Stage private API.

	* clutter/clutter-rectangle.c: Update the get_abs_opacity()
	call to get_paint_opacity().

	* clutter/clutter-stage.c:
	(clutter_stage_get_preferred_width),
	(clutter_stage_get_preferred_height),
	(clutter_stage_allocate),
	(clutter_stage_class_init): Port Stage to the new size
	negotiation API.

	* clutter/clutter-texture.c: Port Texture to the new size
	negotiation API.

	* clutter/clutter-types.h: Add ClutterRequestMode enumeration.

	* clutter/x11/clutter-stage-x11.c: Port the X11 stage
	implementation to the new size negotiation API.

	* tests/Makefile.am: Add the layout manager test case.

	* tests/test-opacity.c: Update.

	* tests/test-project.c: Update.

	* tests/test-layout.c: Test case for a layout manager implemented
	using the new size negotiation API; the layout manager handles
	both transformed and untransformed children.
