We now have two downstream users of stun.h, so it appears to be generally usable. I put this in a new dir networking/, but I'm open to suggestions here (maybe some things in api/ should move in there). I checked what our downstream users are actually using, and it's cricket::ComputeStunCredentialHash cricket::<constants> cricket::TurnMessage cricket::GetStunErrorResponseType cricket::StunAttribute::CreateAddress cricket::StunErrorCodeAttribute cricket::StunByteStringAttribute StunAttribute::CreateUnknownAttributes cricket::TurnErrorType cricket::StunMessage I reckoned that was pretty much everything in stun.h, so I didn't bother splitting it up. They don't use every function and constant in there, but all _types_ of functions and constants, so for the sake of coherence I don't think it makes sense to split it. There's some old stuff in there like GTURN which could arguably be split out, but it should likely go away soon anyway, so I don't think it's worth the effort. Steps: 1) land this 2) update downstream to point to the new header and target 3) remove p2p/base:stun_types.
