Add new client_present and client capabilities fields to QXLRomsetcaps
The client_present field is a byte that is set of non-zero when a
client is connected and to zero when no client is connected.
The client_capabilities[58] array contains 464 bits that indicate the
capabilities of the client. Each bit corresponds to a
SPICE_DISPLAY_CAP_* capability. In particular, if the client has
capability C, then bit (C % 8) in byte (C / 8) is set. The capability
bits only have a defined meaning when a client is connected, ie., when
client_present is non-zero. The number 58 was chosen to fill out a
cache line in QXLRom.
A new QXL_INTERRUPT_CLIENT interrupt is defined, which will be raised
whenever a client connects or disconnects.
