Discard a pane's queued output once it is this far behind, and say so with `pause`.

A data-loss policy rather than backpressure, and unset is a policy too: tmux then buffers until a queued block is five minutes old and closes the connection with `too far behind`. Set this and a slow reader survives having lost output; leave it and a slow enough reader loses the connection. Only meaningful with `pane_output`.

`pause` is the sole report that anything was dropped, and it names the pane. A caller that sets this and ignores notifications has chosen to lose output silently.
