Convert PeriodicWave Audit tests to testharness

Converted tests using the script

for f in `grep -l Audit *.html`
do
  # Replace js-test with testharness and add testharnessreport.js
  sed -i 's;\(.*\)\(<script.*\)js-test.js\(.*\);\1\2testharness.js\3\
\1\2testharnessreport.js\3 ;' $f
  # Remove old js-test methods that no longer exist.
  sed -i '/^[ 	]*\(description(.*)\|finishJSTest()\);[ 	]*$/d' $f
  # Remove jsTestIsAsync stuff
  sed -i '/^[ 	]*window.jsTestIsAsync *= *true;[ 	]*$/d' $f
  # Remove expected results file.
  base=`basename $f .html`
  git rm $base-expected.txt
done

Had to adjust periodicwave-lengths.html manually for uses of
testPassed/testFailed.
