Compute soft deadline in poll() and use nonblocking sockets.
...
Before this commit, anything that touched RawSocket or TapInterface
worked partly by accident and partly because of a horrible crutch
that resulted in massive latencies as well as inevitable packet loss
every time an ARP request had to be issued. Also, there was no way
to use poll() other than by continuously calling it in a busy loop.
After this commit, poll() indicates when the earliest timer expires,
and so the caller can sleep until that moment (or until packets
arrive).
Note that there is a subtle problem remaining: every time poll()
is called, every socket with a pending outbound packet whose
IP address doesn't correspond to a MAC address will send a new
ARP request, resulting in potentially a whole lot of such requests.
ARP rate limiting is a separate topic though.

Before, errors such as packets not fitting into a buffer would have
resulted in panics, and errors such as unbound sockets were
simply ignored.

Don't block forever in TapInterface.

Ideally Devices should be non-blocking, but that would be really
annoying to implement, so for now, to get the examples working,
I'm using this hack.
