shill: Times-out old netlink response handlers.

Adds a default timeout to all message response handlers.  Adds a 'type'
to auxilliary message handlers.  When/if a netlink message goes
unanswered (we don't receive a unicast response with the same serial
number) after the timeout (and there's no intervening sent message -- we
only timeout old handlers on message send), the axilliary message
handler is called with a 'type' of 'timeout' and the handler is deleted.
