* Added handling of event handlers using die(), by queuing "die"

* Added handling of event handlers using die(), by queuing "die"
  events.
* Issue warning when IO::Multiplex has been subject to die() which
  where not caught and queued. (This is known to happen e.g. when
  hitting die() in Varnish::Test::Server::Connection::mux_eof(), so a
  more complete, long-term die()-wrapping solution is needed.)
