#77: [PATCH] make luci.ip.IPvX a bit more forgiving

 Here's a small patch which allows for the following:
 {{{
   ip4 = luci.ip.IPv4("1.2.3.4")
   ip4 = luci.ip.IPv4("::ffff:1.2.3.4")
   ip4 = luci.ip.IPv4("[::ffff:1.2.3.4]")
   ip4 = luci.ip.IPv4("[1.2.3.4]")
   ip6 = luci.ip.IPv6("1::2")
   ip6 = luci.ip.IPv6("[1::2]")
 }}}

 I use this for something like this:

 {{{
 local ip = luci.ip.IPv4(luci.http.getenv("REMOTE_ADDR")):string()
 local mac
 for _, arp in ipairs(luci.sys.net.arptable()) do
         if arp["IP address"] == ip then
                 mac = arp["HW address"]
                 break
         end
 end
 }}}

 Ie. as a simple way to sanitize IPv4 addresses handed in from external
 apps which might put the ::ffff: prefix in front (and square brackets
 around) on IPv6 capable systems.
