Proposal [Trac #1212]: add IPv6 support to network library

Here's the Trac ticket:
This proposal adds two standard protocol-independent functions to
Network.BSD to allow the networking code to work with both IPv6 and IPv4
addresses and protocols.
getAddrInfo is the equivalent of getaddrinfo from RFC 2553. getNameInfo
is the equivalent of getnameinfo from RFC 2553.
These functions rely on a few new types:
AddrInfo AddrInfoFlags NameInfoFlags
Several global values provide mnemonics for query hints and flags.
Both of these functions are available on all modern operating systems.
They unify name and service lookup for IPv4 and IPv6. The code has been
autoconfiscated so that it will not be compiled if IPv6 support is not
I have not touched existing code in any way, save to add and extend the
smallest possible number of types and functions so that IPv6 addresses
can be accommodated.
I would suggest a consideration period of one week, since my changes are
non-intrusive in nature.
