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
