This sets up monitor layout callbacks, and enables input event translation
between the RDP space and the weston desktop. The RDP backend now uses
a heads changed callback instead of the simple head configurator.
We only allow a single monitor for now, but in the future RAIL will make
use of multi-head.
As a side effect, scaling is now supported in RDP sessions.
It should be noted that due to differences between RDP and wayland
representation of their global coordinate spaces, mixing DPI leads to
RDP monitor layouts that can't properly be represented in weston.
