[PATCH] protocol: make pointer images regular surfaces

[Ander Conselvan de Oliveira]

Replace the input_device.attach request with requests for setting
a pointer surface and a hotspot. This surface is client specific and
will be showed as the cursor sprite when one of the clients surfaces
has pointer focus.
