Patch by George Sakkis

#7643: Unicode codepoints VT (0x0B) and FF (0x0C) are linebreaks according to Unicode Standard Annex #14.

Addition of delta keyword argument to unittest.TestCase.assertAlmostEquals and assertNotAlmostEquals

This allows the comparison of objects by specifying a maximum difference; this includes the comparing of non-numeric objects that don't support rounding.

Rename the unittest test_suite function to not clash with a test module name (unittest.test.test_suite is now unambiguous).

A fix for running unittest tests on platforms without the audioop module (e.g. jython and IronPython)

reads and writes are always retried by OpenSSL itself.

(this is a followup to issue #3890)

CObject to PyCapsule.

Fix the following calls: _curses.tigetflag(None), _curses.tigetnum(None),
_curses.tigetstr(None).

optimizations are disabled when --with-pydebug is used.
