This allows support for host/guest clipboard sharing when using vnc
guests (and possibly other graphics types in the future). This channel
is similar to the spicevmc channel, but it contains a couple additional
options to enable/disable clipboard sharing and specify the mouse mode.
In the case of spice, these settings are specified on the 'graphics'
element, but for qemu-vdagent, they are specified on the channel. For
example:
--channel=qemu-vdagent,source.clipboard.copypaste=on,source.mouse.mode=client

+ Communication channel for QEMU vd agent, using virtio serial (requires

+ VNC guests. Note that the guest clipboard integration is implemented via
+ spice-vdagent, which must be running even when the guest does not use spice

Use --channel=? to see a list of all available sub options.
