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

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

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).

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
