qxl: Add set_client_capabilities() interface to QXLInterface
This new interface lets spice server inform the guest whether (a) a client is connected (b) what capabilities the client has There is a fixed number (464) of bits reserved for capabilities, and when the capabilities bits change, the QXL_INTERRUPT_CLIENT interrupt is generated.
