[libvirt] [PATCHv2 0/4]add support for graphics to get a IPv6 address

[Luyao Huang]

https://bugzilla.redhat.com/show_bug.cgi?id=1192318

We already support add a IPv6 address to graphics listen address
and xml like this:

    <graphics type='spice' port='5900' autoport='yes' listen='2001b8:ca2:2::1' keymap='en-us'>
      <listen type='address' address='2001b8:ca2:2::1'/>
    </graphics>

However we do not support get a IPv6 address for the network.

add some helpers and rework networkGetNetworkAddress to make it
can get a IPv6 address when we need.

Luyao Huang (4):
  util: introduce 2 new helpers for get interface IPv6 address
  conf: introduce new family attribute in graphics listen for chose IP
    family
  network: rework networkGetNetworkAddress to make it can get IPv6
    address
  qemu: fix a error coverd issue in 2 place
