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.

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.

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.
