needed.

Remove also an unused variable (blank) in test_threading.

Lehtinen.

Also, reduce code duplication in LargeMmapTests.

Original patch by Steffen Daode Nurpmeso.

`mmap.PROT_READ|mmap.PROT_EXEC` would segfault instead of raising a
TypeError.  Patch by Charles-François Natali.

  Add import_function method to test.test_support, and modify a number of
  tests that expect to be skipped if imports fail or functions don't
  exist to use import_function and import_module.  The ultimate goal is
  to change regrtest to not skip automatically on ImportError.  Checking
  in now to make sure the buldbots don't show any errors on platforms
  I can't direct test on.

  A few more test skips via import_module, and change import_module to
  return the error message produced by importlib, so that if an import
  in the package whose import is being wrapped is what failed the skip
  message will contain the name of that module instead of the name of the
  wrapped module.  Also fixed formatting of some previous comments.
