If a USB keyboard is unplugged, the keyboard eventhandler is never
removed, and events will continue to be passed through to the device,
causing crashes or memory corruption.

Previous commit added QMP documentation to the qemu-monitor.hx
file, it's is a copy of this information.
While it's good to keep it near code, maintaining two copies of
the same information is too hard and has little benefit as we
don't expect client writers to consult the code to find how to
use a QMP command.

For QMP, we just add an attribute which is backwards compatible. For the human
monitor, we add (absolute) to the end of the line.

Right now, DisplayState clients rely on polling the mouse mode to determine
when the device is changed to an absolute device. Use a notification list to
add an explicit notification.

kbd_mouse_is_absolute tells us whether the current mouse handler is an absolute
device. kbd_mouse_has_absolute tells us whether we have any device that is
capable of absolute input.
This lets us tell a user that they have configured an absolute device but that
the guest is not currently using it.

And convert usb-hid to use it (to avoid regression with bisection)
Right now, when we do info mice and we've added a usb tablet, we don't see it
until the guest starts using the tablet. We implement this behavior in order
to provide a means to delay registration of a mouse handler since we treat
the last registered handler as the current handler.
This is a usability problem though as we would like to give the user feedback
that they've either 1) not added an absolute device 2) there is an absolute
device but the guest isn't using it 3) we have an absolute device and it's
active.
By using QTAILQ and having an explicit activation function that moves the
handler to the front of the queue, we can implement the same semantics as
before with respect to automatically switching to usb tablet while providing
the user with a whole lot more information.

Move 200 lines out of vl.c already into common code that only needs to
be compiled once.
