to cover recent locale changes and additions.

1. The assumptions in check_node() were too restrictive:

     - Hardware addresses with universal_local_bit=1 are valid
       (locally administered).

     - Many of the tested functions (including uuid.getnode())
       may return valid RFC 4122 random node IDs. These are pretty
       much random 48-bit values with the multicast bit set to 1.

2. _unixdll_getnode() calls _uuid_generate_time(), which may be None
   on some platforms. The resulting TypeError is now caught.

its tests

The test_classify_oldstyle and test_classify_newstyle methods of
test.test_inspect.TestClassesAndFunctions were previously almost
identical (aside from irrelevant whitespace and one semantic
difference).  They now share a single helper.

Fixes issue #8363.

Try to turn some buildbots green by allowing test_multiprocessing to pass even if it hits the sys.exc_clear code in the threading module, and improve the test coverage by making the ctypes dependencies a bit more granular (two of the cited ctypes objects don't exist on my system)

with earlier versions.

1) A non-critical off-by-one error in pythonw

2) A problem in the configure script that caused
   builds with '--enable-framework --enable-universalsdk=/'
   to fail on OSX 10.6.

Switch regrtest to use StringIO instead of cStringIO for test_multiprocessing on Windows. Issue 8333.

unittest.result.TestResult does not create its buffers until they're used. It uses StringIO not cStringIO. Issue 8333.
