net: need portable api to find network masks from local interfaces

[gopherbot]

by everton.marques:

The functions below don't provide network masks under Windows 7:

    http://golang.org/pkg/net/#InterfaceAddrs
    http://golang.org/pkg/net/#Interface.Addrs

What does 'go version' print?
go version go1.2.2 windows/amd64

What steps reproduce the problem?
1. save http://play.golang.org/p/LNSJnZS-Be to ip.go
2. go run ip.go

What happened?
Under Windows 7, only the ip addresses are shown (but not the netmasks).

What should have happened instead?
Need a portable api to get network masks from local interfaces.

Please provide any additional information below.
