Jason A. Donenfeld d664444928 tun: make customization of WintunPool and requested GUID more obvious 
Persnickety consumers can now do:

    func init() {
        tun.WintunPool, _ = wintun.MakePool("Flurp")
        tun.WintunStaticRequestedGUID, _ = windows.GUIDFromString("{5ae2716f-0b3e-4dc4-a8b5-48eba11a6e16}")
    }

Simon Rozman 3e08b8aee0 wintun: migrate to wintun.dll API 
Rather than having every application using Wintun driver reinvent the

  attempting to create a Wintun interface with a duplicate name.
  Creation is futile.
