Bug Description

A container with an IPv6 address in its configuration (for example, 'lxc.network.ipv6 = 2001:db8:fedc:abcd::2/80') fails to start with the error below.

    lxc-start 1377083732.942 ERROR lxc_confile - No such file or directory - invalid ipv6 address: 2001:db8:fedc:abcd::2/80

This IPv6 address is valid, however, and the same configuration works fine on 12.04.

Ubuntu Release: Ubuntu 13.04
lxc package version: 0.9.0-0ubuntu3.4

SRU justification
1. impact: container configurations specifying an ipv6 address with a mask fail to start
2. Development fix: remove the mask from ipv6 address before passing it to inet_pton
3. Stable fix: same as development fix
4. test case:
   sudo lxc-create -t ubuntu -n x1
   Echo "lxc.network.ipv6 = 2001:db8:fedc:abcd::2/80" | sudo tee -a /var/lib/lxc/x1/config
   sudo lxc-start -n x1
5. Regression potential: none, we are simply passing the correct buffer to inet_pton.
