Add unit tests for the parser

This changeset adds support for JUnit4 tests to icedtea-web. It also adds some
parser tests that check that the parser works. make check will now run these
tests if JUnit is available.

2011-03-31  Omair Majid  <[email protected]>

    Add unit tests for the parser
    * Makefile.am: Add TESTS_DIR,TESTS_SRCDIR, NETX_UNIT_TEST_DIR,
    and NETX_UNIT_TEST_SRCDIR, JUNIT_RUNNER_DIR, JUNIT_RUNNER_SRCDIR, and
    JUNIT_RUNNER_JAR. Conditionally define RHINO_TESTS and UNIT_TESTS.
    (clean-local): Use RHINO_TESTS and UNIT_TESTS.
    (clean-tests): Depend on clean-netx-tests. Delete directory.
    (junit-runner-source-files.txt, $(JUNIT_RUNNER_JAR)),
    (next-unit-tests-sources-files.txt stamps/netx-unit-tests-compile.stamp),
    (run-netx-unit-tests, clean-netx-tests, clean-junit-runner)
    (clean-netx-unit-tests): New targets.
    * configure.ac: Add new optional dependency on junit.
    * tests/junit-runner/CommandLine.java,
    * tests/junit-runner/LessVerboseTextListener.java,
    * tests/junit-runner/README,
    * tests/netx/unit/net/sourceforge/jnlp/ParserBasicTests.java,
    * tests/netx/unit/net/sourceforge/jnlp/ParserCornerCaseTests.java,
    * tests/netx/unit/net/sourceforge/jnlp/ParserMalformedXmlTests.java,
    * tests/netx/unit/net/sourceforge/jnlp/basic.jnlp: New files.

+junit-runner is used to run tests instead of the standard runner
+org.junit.runner.JUnitCore.  It provides output similar to that used by JTreg,
+which is useful for automated comparison.
