ui/cocoa: Fix handling of absolute positioning devices
Fix handling of absolute positioning devices, which were basically
unusable for two separate reasons:
(1) as soon as you pressed the left mouse button we would call
CGAssociateMouseAndMouseCursorPosition(FALSE), which means that
the absolute coordinates of the mouse events are never updated
(2) we didn't account for MacOSX coordinate origin being bottom left
rather than top right, and so all the Y values sent to the guest
were inverted
We fix (1) by aligning our behaviour with the SDL UI backend for
absolute devices:
* when the mouse moves into the window we do a grab (which means
hiding the host cursor and sending special keys to the guest)
* when the mouse moves out of the window we un-grab
and fix (2) by doing the correct transformation in the call to
qemu_input_queue_abs().
