Summary: Add inet_pton and inet_ntop to socket

Initial Comment:
Patch is against current CVS and adds two socket module
functions, inet_pton and inet_ntop.  Both of these
should be available on all platforms (because of other
dependancies in the code) so I don't think portability
is a problem.  inet_ntop converts a packed IP address
to a human-readable '.' or ':' separated string
representation of the IP.  inet_pton performs the
reverse operation.

(Potential) problems: inet_pton sets errno to ENOSPC,
which may lead to a confusing error message.

The use case I have for it at the moment is a DNS server
(Twisted.names).  inet_pton allows me to handle IPv6
addresses, so it allows me to support AAAA and A6 records. 
I believe an IPv6 capable socks proxy would find this useful
as well.  Basically, low level network stuff.

What is the rationale for providing this functionality?

Ooops, I made two, and uploaded the wrong one >:O  Sorry. 
Dunno if it's still helpful, but here's the unified diff.
