Various tests fail when run under coverage. A primary culprit is refcount tests
which fail as the counts are thrown off by the coverage code. A new decorator
-- test.support.refcount_test -- is used to decorate tests which test refcounts
and to skip them when running under coverage. Other tests simply fail because
of changes in the system (e.g., __local__ suddenly appearing).
Thanks to Kristian Vlaardingerbroek for helping to diagnose the test failures.
Many tests simply didn't care if they unset a pre-existing trace function. This
made test coverage impossible. This patch fixes various tests to put back any
pre-existing trace function. It also introduces test.support.no_tracing as a
decorator which will temporarily unset the trace function for tests which
simply fail otherwise.
Thanks to Kristian Vlaardingerbroek for helping to find the cause of various
trace function unsets.

Issue #10806, issue #9905: Fix subprocess pipes when some of the standard
file descriptors (0, 1, 2) are closed in the parent process. Initial
patch by Ross Lagerwall.
........
In order to create symlinks on Windows, SeCreateSymbolicLinkPrivilege
is an account privilege that is required to be held by the user. Not only
must the privilege be enabled for the account, the activated privileges for
the currently running application must be adjusted to enable the requested
privilege.
Rather than exposing an additional function to be called prior to the user's
first os.symlink call, we handle the AdjustTokenPrivileges Windows API call
internally and only expose os.symlink when the privilege escalation was
successful.
Due to the change of only exposing os.symlink when it's available, we can
go back to the original test skipping methods of checking via `hasattr`.

Replace the "compiler" resource with the more generic "cpu", so
as to mark CPU-heavy tests.

Issue #9792: In case of connection failure, socket.create_connection()
would swallow the exception and raise a new one, making it impossible
to fetch the original errno, or to filter timeout errors. Now the
original error is re-raised.

Improve transient_internet() again to detect more network errors,
and use it in test_robotparser. Fixes#8574.
........
* Use the current filesystem encoding instead of always using utf-8
* Enable the test on Mac OS X
* Use TESTFN_UNENCODABLE and TESTFN_UNICODE instead of arbitrary filenames
* To decode a filename, use strict error handler instead surrogateescape for
mbcs encoding (on Windows)
* Use TESTFN_UNENCODABLE (if available) for the directory name
Skip the test if no non-ascii filename can be created.
* Use 0xff byte on non-Windows OSes
* mbcs is now really strict by default: i closed the issue #850997, so use the
filesystem encoding and not Latin-1
* Rename TESTFN_UNICODE_UNENCODEABLE to TESTFN_UNENCODEABLE
Added Windows support for os.symlink when run on Windows 6.0 or greater,
aka Vista. Previous Windows versions will raise NotImplementedError
when trying to symlink.
Includes numerous test updates and additions to test_os, including
a symlink_support module because of the fact that privilege escalation
is required in order to run the tests to ensure that the user is able
to create symlinks. By default, accounts do not have the required
privilege, so the escalation code will have to be exposed later (or
documented on how to do so). I'll be following up with that work next.
Note that the tests use ctypes, which was agreed on during the PyCon
language summit.
