This patch series enables support for the qemu-vdagent character device which
enables copy/paste support between guest and client when using vnc graphics.
The guest must be configured with something like the following:
<channel type='qemu-vdagent'>
<source>
<clipboard copypaste='yes'/>
<mouse mode='client'/>
</source>
<target type='virtio' name='com.redhat.spice.0'/>
</channel>
Copy/paste sync requires a vnc client that has support for copy/paste commands.
Currently virt-viewer does not work, but the version of tigervnc provided by
fedora (executable name 'vncviewer') does work.
More details about this device on Gerd's blog:

For now I have left the target to be configurable to match the spicevmc
channel, although Marc-Andre has suggested to simply hard-code it to the virtio
name com.redhat.spice.0
Changes in v2:
- change xml syntax to use <clipboard> and <mouse> sub-elements of <source>
defined in the same way as they are for the spice display.
- fix a build failure when apparmor was enabled
- Add another test for when features are turned off
