Alon Levy d1a6f3dfd8 qxl_dev.h: add client monitors configuration notification to guest 
So far we have used the agent to notify the guest of a request to change
the monitors configurations (heads) on the qxl device. This patch introduces
a new interrupt and new fields in the qxl rom to notify the guest about
a new request, similarly to how physical hardware notifies the driver.

We compute crc over the monitors configuration to avoid host-write from a
following update while guest-read corruption. The update protocol is:

qemu:
  (2) fill QXLRom::client_monitors_config
  (3) raise QXL_INTERRUPT_CLIENT_MONITORS_CONFIG

guest:
  (1) clear QXL_INTERRUPT_CLIENT_MONITORS_CONFIG bit in irq status
  (2) read QXLRom::client_monitors_config
  (3) (verify-crc)? done : goto 2

If the interrupt mask is ~0 or 0, or does not have
QXL_INTERRUPT_CLIENT_MONITORS_CONFIG set, we also assume it doesn't support
this interrupt.
