Message:

Device/Graphics, pdm, Main, Front-ends: infrastructure for host software cursor.
bugref:9376: Complete hardware cursor implementation in VMSVGA.
This change provides the infrastructure for letting front-ends report to the
graphics device that they are able to render a pointer cursor at any location,
not just where the host cursor is, and for the device to ask them to do this.
It also provides mediation in Main/Display between multiple front-ends and the
device, and tells the guest that we can always render the cursor. In a
follow-up change the device is expected to add support for rendering the
cursor itself into the frame-buffer image it provides to the front-end if not
all attached front-ends are capable of rendering it.
