IPv6 support patches for network - please apply

[Bryan O'Sullivan]

Hi -

As there's been no recent discussion of my patches to add IPv6 support 
to the network library, and I've resolved every question and comment 
that people had, I propose that they now be applied.

The trac ticket is here:

   http://hackage.haskell.org/trac/ghc/ticket/1212

And the darcs patches against network are here:

Thanks,
