[libvirt] [PATCH] spice: expose the disable file transfer option

[Francesco Romani]

spice-server offers an API to disable file transfer messages
on the agent channel between the client and the guest.
This is supported in qemu through the disable-agent-file-xfer option.

This patch exposes this option to libvirt.
