[PATCH v3 9/9] net: support to include ipv6 address by brackets

[Amos Kong <akong@redhat.com>]

That method of representing an IPv6 address with a port is
discouraged because of its ambiguity. Referencing to RFC5952,
the recommended format is:

     [2312::8274]:5200

For IPv6 brackets must be mandatory if you require a port.

test status: Successed
listen side: qemu-kvm .... -incoming tcp:[2312::8274]:5200
client side: qemu-kvm ...
             (qemu) migrate -d tcp:[2312::8274]:5200
