jtreg testing integrated

Thanks for jtdiff.


- The various help options are confusing.
  Just print all the help available if given -help or -usage.
- The usage should give a paragraph explaining what it does.
  Not too much work; why, you've practically written the required
  words in the quoted text below.
- My first version of diff-javatest was symmetrical.  It printed any
  difference between the two runs, in both directions.  Later I
  realized that (at least my own) usage invariably had the notion
  of a "reference" JDK and a "test" JDK.  I was interested in tests
  run in the "test" JDK but not in the reference JDK, but not vice
  versa; typically the reference JDK results were historical ones
  produced by someone wearing a QA hat, and were more complete
  than the ones in the test JDK, where results were more likely to be
  part of an edit-compile-test cycle.

Try printing the usage message from my own diff-javatest script,
which should still be accessible inside Sun, in /java/tl, for example.
