detect which scopes a interface can be used for

[dominictarr]

fixes https://github.com/ssbc/ssb-config/issues/63

binds each interface to just one scope. that means sbot.getAddress('local') will return a 192... (or whatever, possibly including ipv6, etc. and sbot.getAddress('device') will return 'localhost'.

basically this was the code inside of non-private-ip, which was just a wrapper for the ip module but assumed you wanted a single host which made sense before we had multiserver and scopes etc

[dominictarr]

also tried to make better documentation

@mixmix @christianbundy thoughts?

here's the ouput I got running this locally. Seems good to me

hmmm .. . I tested this on windows + linux.

It looks to be generating sensible output, and it seems to be forming connections between windows + linux on the local wifi. The problem is that I think we need to test discovery + connection in both directions and not sure how best to do that.

ok turned off internet and saw a message replicated locally fine from Linux > windows. I'm merging this

Dominic there are now 2 sections with Scope, I'm gonna merge those

MISSING ip dependency!

thanks @dominictarr :heart:

thanks @mixmix note to other maintainers: mix's home wifi gives a public ipv6 address (actually, two!), which is fairly unusual.
