[virt-tools-list] [PATCH v2 1/3] Add VirtualCharSpicevmcDevice



Here is an example of resulting XML:

    <channel type='spicevmc'>
      <target type='virtio' name='com.redhat.spice.0'/>
    </channel>

Updated since v1:
- splitted the address bits in a seperate patch
- added --channel spicevmc documentation in man/en/virt-install.pod.in
