Message:

allow compositor and console to coexist side-by-side, use the input server as a poor man's seat arbitrator

• kernel console notifies both about the release and grab events
• input server arbitrates the seat selection between kernel console and any number of user space UIs (currently the console server and the compositor server)
• input port yield and reclaim methods have been removed (they are used only on Ski and Niagara, both already need a more generic mechanism for the kernel/user space cooperation)
• console and compositor server keep track of the kernel console via the input arbitration
• move the waiting for a character device from init and terminal widget to getterm
