Jason A. Donenfeld 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.

Simon Rozman 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.

Simon Rozman b7025b5627 wintun: Add TUN device locking 
In case reading from TUN device detected TUN device was closed, it
closed the file handle and set tunFile to nil. The tunFile is
automatically reopened on retry, but... If another packet comes in the
WireGuard calls Write() method. With tunFile set to nil, this will
cause access violation.

Therefore, locking was introduced.

Simon Rozman 6581cfb885 wintun: Move exchange buffer in separate struct on heap 
This allows buffer alignment and keeps it together with its meta-data.

Furthermore, the write buffer has been reduced - as long as we flush
after _every_ write, we don't need a 1MiB write buffer.
