Move B_MOUSE_IDLE generation to app_server.

* BWindow used to generate the B_MOUSE_IDLE events by sending a
delayed message with a one-shot BMessageRunner to itself.
Every creation and deletion of BMessageRunners causes synchronous
messaging between the application under the mouse cursor and the
registrar. This creates large amounts of calls to set_port_owner()
in the kernel whenever moving the mouse.

* Now, B_MOUSE_IDLE is sent by the cursor loop inside the app_server
instead. When the mouse wasn't moved for the tooltip delay time,
it inserts a B_MOUSE_IDLE message into the event stream.

* The tooltip delay thus becomes a system-wide constant and is not
configurable per-application anymore (no code currently in the
Haiku repo makes use of that anyhow).


# 95530739 17-Oct-2008 Axel Dörfler <axeld@pinc-software.de>

* Reworked EventDispatcher::SendFakeMouseMoved() after an idea by Stephan
that solves most app_server locking headaches: it now works asynchronously,
and therefore doesn't need to lock the EventDispatcher anymore.
* EventStreams now allow to inject messages into the stream to allow the above
functionality.
* InputServerStream::GetNextEvent() no longer returns when there is no event.
* Desktop::ActivateWindow() now locks all windows before checking the
workspaces of the windows, fixing a race condition that could lead to
Window::Foremost() being called for a window that isn't on the current
workspace, leading to a crash.
* I currently cannot access Trac, but I recall there should be an open bug
report about this.

# 92b292f5 10-Jan-2006 Axel Dörfler <axeld@pinc-software.de>

Implemented B_NO_POINTER_HISTORY. Window moving/resizing uses this mechanism
as well now, and makes quite a difference in Qemu.
Not tested for standard BViews, though.

The input_server is now notified when the screen resolution is changed.

* the new input event dispatcher is now actually used, although it doesn't
distribute any messages to the clients yet.
* removed the working thread from RootLayer - for now, its event handlers are
still called using input filters in the new event dispatcher, though (to
get things started).
* ServerApp is now using a BMessenger to identify its client, and no longer
stores the port/token separately.
* the input_server handshake is a bit simpler now, as it can now just reply
to the app_server message, removed unused code from ServerProtocol.h
* calmed down the MultiLocker (it always printed thread statistics on startup,
because it's compiled in debug mode).
* removed the cursor thread stuff from AppServer.cpp
* the new event dispatcher now uses a cursor thread when supported (only in
native mode, not in the test environment), although it improves cursor
movement under Qemu, the effect is not as good as expected - this might
need some more investigations (might just be a thread priority problem).

# 08f35604 17-Nov-2005 Axel Dörfler <axeld@pinc-software.de>

The basics of the new event handling - not yet connected to anything, and therefore
neither used nor tested. It's not even complete yet (support for Set[Mouse]EventMask()
is missing), but it will get there :)
