There's still a tiny race on Linux, since the tun channel is written to

Jason A. Donenfeld 5a267f0b8c timers: no need to clear keepalive in persistent keepalive 
We do this after sending the keepalive anyway.

This is something of a regression, though, since before we'd cancel and
then send, but now we send and then cancel, so it introduces a potential
race, but hopefully that isn't too big of a deal.

Jason A. Donenfeld 870734ab5e timers: clear send_keepalive timer on sending handshake response 
We reorganize this into also doing so on sending keepalives itself,
which means the state machine is much more consistent, even if this was
already implied.

Mathias Hall-Andersen 2a432523ed Listen for flush in outer select 
Now listen for flushNonceQueue signal in outer select during
the RoutineNonce routine. This is needed to handle the edge case
where the queue is flushed, but no packets are in the nonce queue.
Since the signal has capacity 1 this signal will remain and potentially
flush the queue at a later time, with packets meant for transmission.
