qxl: Add set_client_capabilities() interface to QXLInterface

Browse Source 
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.
