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.

Simon Rozman 5981d5cacf wintun: Check for user close in read loop regardless the load 
Do the WaitForSingleObject() always to provide high-load responsiveness.

Reorder events so TUN_SIGNAL_CLOSE has priority over
TUN_SIGNAL_DATA_AVAIL, to provide high-load responsiveness at all.

Jason A. Donenfeld 2e772194cf tun: only call .Fd() once 
Doing so tends to make the tunnel blocking, so we only retrieve it once
before we call SetNonblock, and then cache the result.
