This patch adds virtio-input support to qemu. It brings a abstract
base class providing core support, other classes can build on it to
actually implement input devices.
virtio-input basically sends linux input layer events (evdev) over
virtio.

To: qemu-devel; +Cc: Cornelia Huck, Gerd Hoffmann, mst
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.

This patch adds virtio-pci support for the emulated virtio-input
devices. Using them is as simple as adding "-device virtio-tablet-pci"
to your command line. If you want add multiple devices but don't want
waste a pci slot for each you can compose a multifunction device this way:
qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \
-device virtio-tablet-pci,addr=0d.1,multifunction=on

Help us complete virtio 1 support in 2.4?
