Improved IPv6 support

As the IPv6 protocol allows a single device to have more than one IPv6 address,
the previous implementation did not provide all IPv6 information.  It would reject
all except the last parsed IPv6 address.

NOTE: This implementation will break the previous API.

This change removes the ethtool.etherinfo.ipv6_address and
ethtool.etherinfo.ipv6_netmask members.  A new member is added,
ethtool.etherinfo.ipv6_addresses (in plural).  This contains a tupple list
containing of ethtool.etherinfo_ipv6addr objects, one object for each configured
IPv6 address on the device.  These objects have the following members available:

  .address       - The IPv6 address
  .netmask       - The IPv6 netmask (in bit notation)
  .scope         - A string with the IPv6 address scope

Example code:

	import ethtool

	devs = ethtool.get_interfaces_info('eth0')
	for ip6 in devs[0].ipv6_addresses:
	    print "[%s] %s/%i" % (ip6.scope, ip6.address, ip6.netmask)
