    Bring in a simple event tracing library and POC utility
    
    - Import libevtr, a library for abstracting access to an event stream.
      libevtr uses its own dump format and can synthesize event attributes
      based on known event types.
    - Modify ktrdump(8) to be able to dump an event stream to a file
      using libevtr.
    - Add evtranalyze(1), a proof of concept utility to display events in
      a line-oriented text format or to generate an svg file displaying
      the events on each processor. This needs quite some work.
