This patch adds the virtio-input-hid base class and
virtio-{keyboard,mouse,tablet} subclasses building on the base class.
They are hooked up to the qemu input core and deliver input events
to the guest like all other hid devices (ps/2 kbd, usb tablet, ...).
Using them is as simple as adding "-device virtio-tablet-device" to
your command line, for use all transports except pci. virtio-pci
support comes as separate patch, once virtio-pci got virtio 1.0
support.
