Resurrect Aura Linux accessibility.
This is based in part on the ATK code we had as part of the Linux GTK port
that went away, but now rewritten on top of AXPlatformNode. This patch
successfully exposes an accessibility tree for Views and exposes top-level
windows and the the role and name of each View. You can test it using
accerciser. This is just to get the infrastructure in place - we need to
implement more of the interface for it to be useful for accessibility tools.
