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.
