[Spice-devel] [spice-server] Notify QXL instance upon change of mouse mode

[yuri.benditovich at daynix.com]

From: Yuri Benditovich <yuri.benditovich at daynix.com>

When mouse mode (client/server) changed, spice server
notifies QXL instance to allow QEMU to optimize cursor-related
traffic from guest to host.
