* Rewrote event handling: instead of writing every single device message to
the event port, they are just queued in a list, and the event loop is only
notified if necessary (ie. if a notification has been sent already, new
events are just queued up until the input_server found the time to process
them).
* This also fixed a big memory leak: every message processed by EnqueueDeviceMessage()
(IOW every key or mouse event) was leaked!
* no longer abuses gInputMethodListLocker to lock the method event queue
(it now uses the standard event queue lock).
* removed the completely superfluous, weird and decelerating event caching mechanism
* tried to find a better distribution of work between _SanitizeEvents(),
_MethodizeEvents(), and _DispatchEvents().
* HandleSetMousePosition() now only does what it's supposed to do (this currently
causes the mouse to jump at the start, though).
* now uses the "Message4" for message sending if available.
* fixed "kb_mouse_settings.h" to include all headers it needs.
* some more cleanup.

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.
