  Issue #7449 part 3, test_doctest: import trace module in test_coverage()

  Import trace module fail if the threading module is missing. test_coverage() is
  only used if test_doctest.py is used with the -c option. This commit allows to
  execute the test suite without thread support.

  Move "import trace" in test_coverage() and use
  test_support.import_module('trace').

  Issue #7449, part 4: skip test_multiprocessing if thread support is disabled

  import threading after _multiprocessing to raise a more revelant error message:
  "No module named _multiprocessing". _multiprocessing is not compiled without
  thread support.

  Issue #7449, part 5: split Test.test_open() of ctypes/test/test_errno.py

   * Split Test.test_open() in 2 functions: test_open() and test_thread_open()
   * Skip test_open() and test_thread_open() if we are unable to find the C
     library
   * Skip test_thread_open() if thread support is disabled
   * Use unittest.skipUnless(os.name == "nt", ...) on test_GetLastError()

  Issue #7449, part 7: simplify threading detection in test_capi

   * Skip TestPendingCalls if threading module is missing
   * Test if threading module is present or not, instead of test the presence of
     _testcapi._test_thread_state

  Issue #7449, part 8: don't skip the whole test_asynchat if threading is missing

  TestFifo can be executed without the threading module

  Issue #7449, part 9: fix test_xmlrpclib for missing threading module

   * Skip testcases using threads if threading module is missing
   * Use "http://" instead of URL in ServerProxyTestCase if threading is missing
     because URL is not set in this case
........
  r80569 | victor.stinner | 2010-04-28 01:33:58 +0200 (mer., 28 avril 2010) | 6 lines

  Partial revert of r80556 (Issue #7449, part 5, fix ctypes test)

  Rewrite r80556: the thread test have to be executed just after the test on
  libc_open() and so the test cannot be splitted in two functions (without
  duplicating code, and I don't want to duplicate code).

  r80570 | victor.stinner | 2010-04-28 01:51:16 +0200 (mer., 28 avril 2010) | 8 lines

  Issue #7449, part 10: test_cmd imports trace module using test_support.import_module()

  Use test_support.import_module() instead of import to raise a SkipTest
  exception if the import fail. Import trace fails if the threading module is
  missing.

  See also part 3: test_doctest: import trace module in test_coverage().

  Issue #7449, last part (11): fix many tests if thread support is disabled

   * Use try/except ImportError or test_support.import_module() to import thread
     and threading modules
   * Add @unittest.skipUnless(threading, ...) to testcases using threads
