future Python to the safer and more often desired value of True.

DeprecationWarnings that show up in a lot of existing code are controversial
and have caused pain in the past.  I'd like to leave this on for 3.2 beta1 and
see how things go.  We can remove the warning if it is deemed too noisy during
any betas.  (case study: the md5 and sha module DeprecationWarnings are loathed
around the world as those modules were never going to be removed in 2.x and
2to3 has a fixer for code that uses them)

Added a few common Popen uses to the tests like we've done for a few other
instances of adding context managers. Eventually the entire test suite
could be converted to use the context manager format.

  subprocess.Popen.__del__ referenced global objects, which is a no-no thanks to
  interpreter shutdown semantics. Same issue goes for the methods that __del__
  called. Now all the methods capture the global objects it needs as default
  values to private parameters (could have stuck them on the class object itself,
  but since the objects have nothing directly to do with the class that seemed
  wrong).

  There is no test as making one that works is hard. This patch was
  verified against a consistently failing test in Mercurial's test suite, though,
  so it has been tested in some regard.

  Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
  Genellina for writing another patch for the same issue and attempting to write
  a test.

    now qualified by _subprocess.ATTR rather than importing *.
