Instead, we introduce a default_qmp flag.  We don't use it yet, but will in the
next patch.

This has a user-visible impact as specifying just -qmp will now also show a
monitor on the 'vc'.

Right now, downscript is not invoked reliably.  If you execute 'quit' from the
monitor, it won't be invoked.

This fixes that by converting tap to use an exit_notifier to execute the
downscript.  In this case, allowing an exit notifier to include state is
critically important for the conversion.
Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

All of these users have global state so we really don't see a benefit from
exit_notifier.  However, using exit_notifier means that there's one less
justification for having global state in the first place.

Today we poll the mouse mode whenever there is a mouse movement.  There is a
subtle usability problem with this though.

If we're in relative mode and grab is enabled, when we change to absolute mode,
we break grab.  This gives a user a seamless transition when the new pointer
is enabled.

But because we poll for mouse change, this grab break won't occur until the user
attempts to move the mouse.  By using notifiers, the grab break happens as soon
as possible.

When we switch to absolute mode, we send out a notification (if the client
supports it).  Today, we only send this notification when the client sends us
a mouse event and we're in the wrong mode.

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.

Notifiers are data-less callbacks and a notifier list is a list of registered
notifiers that all are interested in a particular event.

We'll use this in a few patches to implement mouse change notification.
