If a interface or network have both ipv6 and ipv4 address which can be used,
we do not know use which be a listen address. So introduce a new attribute
to help us chose this.
graphics XML will like this after this commit:
<graphics type='spice' port='5900' autoport='yes'>
<listen type='network' address='192.168.0.1' network='vepa-net' family='default'/>
</graphics>
and this ip family can be set 3 type:
default: check if the interface or network have a can be used ipv4 address,
if yes use this address, if not will try to get a ipv6 address.
ipv4: check if the interface or network have a can be used ipv4 address
ipv6: check if the interface or network have a can be used ipv6 address
fix some test which will be break by this commit.
