Jason A. Donenfeld 5e924e5407 Avoid deadlock when the mutex isn't required, since these are atomics

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.
