[PATCH 0/4] Implement virtio-multitouch and enable GTK3 to use it

[Sergio Lopez]

This series adds a virtio-multitouch device to the family of devices emulated
by virtio-input implementing the Multi-touch protocol as descripted here:

https://www.kernel.org/doc/html/latest/input/multi-touch-protocol.html?highlight=multi+touch

It also extends the GTK UI backend to be able to receive multi-touch events
and transpose them to a guest, so the latter can recognize them as gestures
when appropriate.

An example of this in action can be seen here:

  virtio-input: generalize virtio_input_key_config()
  virtio-input: add a virtio-mulitouch device
