git daemon has a feature called interpolated paths

If git daemon is started like this:
     git daemon --interpolated-path=%IP/%D
(the machine has two IPs: 123.123.123.123 (v4) and 2001:db8::1 (v6))
and someone clones a repository:
     git clone git://123.123.123.123/frotz
git daemon will look for the repository in the directory  
`123.123.123.123/frotz'

But if git daemon listens on the IPv6 interface and someone clones a  
repository:
     git clone git://2001:db8::1/frotz
Then git daemon will look for the repository in `0.0.0.0/frotz'

My patch makes it converting IPv6 addresses properly and if you the clone in my previous example it'll now look in `2001:db8::1/frotz' (with colons in the directory name)

I hope my intentions are now a bit clearer ;)
