And then call:

    call_cosole_driver(con, text, len, dropped_text, DROPPED_TEXT_MAX);

Is that better? We do not want to pass the actual buffer size because
the buffer is shared with the regular messages.

Later in this series the dropped messages are handled in quite a
different way, so maybe this mid-series solution is acceptable. But even
by the end of this series DROPPED_TEXT_MAX still exists just to put a
limit on the dropped messages length, even if more buffer space exists.
