jow fad2bfb9e1 Add new package for configuring 6rd tunnels.
This patch adds support for manually configuring 6rd tunnels. It depends on
the netifd patches I sent earlier, which add 6rd support.

A basic interface configuration looks like:

    config interface 'wan6'
      option proto '6rd'
      option peeraddr '192.0.2.1'
      option ip6prefix '2123::'
      option ip6prefixlen '16'
      option ip4prefixlen '0'

Where ip4prefixlen is optional and actually defaults to 0, which would use all
bits of the IPv4 in the calculated IPv6 subnet.

I believe it should be possible to configure a regular 6to4 tunnel using this,
and that we may want to merge the two eventually, but there are some larger

differences between the two at the moment:

 - 6rd addresses can be more difficult to calculate. My ISP, for example, has
   a setup with a v6 mask of 43 bits, and a v4 mask of 19.

 - 6to4 has support for configuring radvd. This is something we want, of
   course, but it seems best to deal with this in a separate patch.

Just creating a new package looked like the quickest way to get this in.

This work is based on the 6in4 package, and work by Stijn Tintel.
