net: implement ECN handling, rfc6040 style 
To decide whether we should use the compatibility mode or the normal
mode with a peer, we use the handshake messages as a signaling channel.

If we receive the expected ECN bits, it most likely means they're
running a compatible version.

send: propagate DSCP bits to the outer tunnel 
Like many, I am using WiFi a lot and often on congested networks.
 Without this, Wireguard strips the DSCP bits, preventing WME from
 kicking in and improving the audio/video experience.

Yes, it's technically an information leak. Who cares? It's not like if
traffic analysis based on packet sizes or timings wasn't a thing.

This is the first patch of the serie, more work has to happen on ECN

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.

c15cbefc12 Reorder data-types and functions to match SetupAPI.h 
Adding functions with non-consistent order made setupapi package a mess.
While we could reorder data-types and functions by alphabet - it would
make searching easier - it would put ...Get... and ...Set... functions
quite apart.

Therefore, the SetupAPI.h order was adopted.
