Subject: [PATCH] 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.
