* Introduced a new handshake between input_server and app_server, and some

temporary handling code in the app_server.
* RootLayer no longer creates the input_server messaging port - this is now
  the responsibility of the input_server.
* Moved AS_CREATE_[OFFSCREEN_]WINDOW from ServerApp::_MessageLooper() to
  _DispatchMessage().
* The RootLayer thread is now started as soon as the input_server is there.
* removed or disabled any input_server stuff in the AppServer class.
* removed old message commmands to the app_server.
* Removed the R5_CURSOR_COMM and HAIKU_APPSERVER_COMM definitions: the
  input_server is now automatically built correctly depending on the target.
* InputServer::EventLoop() plays now safe and checks for error conditions.
* InputServer::EnqueueDeviceMessage() seems to leak memory, added TODO about
  this.
* InputServer event loop messaging uses ports for inner-app communication - why?
* The InputServer event loop thread is no longer killed on exit, it just quits
  when its port is gone.
* Minor cleanup in input_server.
