Rewrite mouse handlers to use QTAILQ and to have an activation function
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.
