Convert StereoPanner tests to testharness

The following script was used to convert the tests:

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`
  if [ -f $base-expected.txt ]; then
      git rm $base-expected.txt
  fi
done

Some manual adjustments needed in stereopanner-testing.js to replace
the calls to testPassed/testFailed.

stereopannernode-basic.html was converted by hand to use testharness
and new Audit.
