da61947ec3 tun: windows: mitigate infinite loop in Flush()
It's possible that for whatever reason, we keep returning EOF, resulting
in repeated close/open/write operations, except with empty packets.

6a0a3a5406 wintun: revise GetInterface()
- Make foreign interface found error numeric to ease condition
  detection.
- Update GetInterface() documentation.
- Make tun.CreateTUN() quit when foreign interface found before
  attempting to create a Wintun interface with a duplicate name.
  Creation is futile.
