backported to Python 2.3+.  Some of the features desired include better
  verbose reporting in unittest2.TextTestRunner and decorator support for
  skipping tests and expected failures.

o Modified the existing .py tests to use unittest2 and decorated
  TestSTL.test_step_into_stl(), which is known to always fail currently, with
  @unittest2.expectedFailure.

because unittest.main() calls sys.exit() before returning.  Fixed by registering
an exit handler for this situation.

module lldbtest.py and refactored the existing test cases to derive from the
abstract base class lldbtest.TestBase.

MOdified the test driver (dotest.py and dotest.pl) to set up additional
PYTHONPATH component for locating the lldbtest module, which sits in the same
directory.

is defined.  Use ${LLDB_LOG} to specify the log file.

Create a singleton SBDebugger in the lldb namespace, that gets used when running
the entire test suite.

this seems to alleviate the intermittent failure observed while running the
whole test suite.

Also modified dotest.py so that it sets the LLDB_TEST environment variable
so that individual test cases can locate their supporting files correctly.

lldb.SBDebugger.Initialize()/Terminate() pair.

Change TestHelp.py to use synchronous debugging, which is easier to work with.

shell and issuing 'help' would hang (was actually infinitely looping).
