The slightly modified tests continue to pass. The General test
broken by the switch to Notebook is fixed.
Patch mostly by Cheryl Sabella.

Initial patch by Peter Thomassen.

Bug appears to be incomplete copy-paste-edit.

The notebook looks a bit better.  It will work better with separate page classes. Traversal of widgets by Tab works better.  Switching tabs with keys becomes possible.  The font sample box works better at large font sizes.

One of the two simulated click tests no longer works.  This will be investigated while fixing a bug with the widget itself.

Add clear method for tests.  Adjust tests to use global instance.
Remove unneeded ConfigDialog method.

Instance tracers manages pairs consisting of a tk variable and a
callback function.  When tracing is turned on, setting the variable
calls the function.  Test coverage for the new class is 100%.

Write the temporary file on disk and then get its modification time.

test_subprocess now also calls reap_children() in tearDown(), not
only on setUp().

* Update 'Porting to .37' section.

* Fix a minor example in the doc.

The changes for bpo-29585 eliminate the extra imports on macOS that caused
the original test failure.

This reverts commit 8a2150aa.

Finish resorting the 72 ConfigDialog methods into 7 groups that represent the dialog, action buttons, and font, highlight, keys, general, and extension pages.  This will help with continuing to add tests and improve the pages. It will enable splitting ConfigDialog into 6 or 7 more comprehensible classes. 

There is a bug in FreeBSD CURRENT with 64-bit dev_t. Skip the test if
dev_t is larger than 32-bit, until the bug is fixed in FreeBSD
CURRENT.

* bpo-31028: Fix test_pydoc when run directly

Fix get_pydoc_link() of test_pydoc to fix "./python
Lib/test/test_pydoc.py": get the absolute path to __file__ to prevent
relative directories.

* Use realpath() instead of abspath()

* In configdialog: Document causal pathways in create_page_general.
Move related functions to follow this. Simplify some attribute names.
* In test_configdialog: Add tests for load and helplist functions.
Coverage for the general tab is now complete, and 63% overall.

The new class manages pairs of tk Variables and trace callbacks.
It is completely covered by new tests.

fixes regression of 5b4feb7e

multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.

The change prevents leaking "dangling" processes.

* bpo-31034: Reliable signal handler for test_asyncio

Don't rely on the current SIGHUP signal handler, make sure that it's
set to the "default" signal handler: SIG_DFL.

* Add comments

* bpo-31009: Fix support.fd_count() on Windows

On Windows, test.support.fd_count() now calls
msvcrt.CrtSetReportMode() to not kill the process nor log any error
on stderr on os.dup(fd) if the file descriptor is invalid.

* Fix for release mode

* Close explicitly queues to make sure that we don't leave dangling
  threads
* test_queue_in_process(): remove unused queue
* test_access() joins also the process to fix a random warning

bpo-26762: test_multiprocessing now detects dangling processes and
threads per test case classes:

* setUpClass()/tearDownClass() of mixin classes now check if
  multiprocessing.process._dangling or threading._dangling was
  modified to detect "dangling" processses and threads.
* ManagerMixin.tearDownClass() now also emits a warning if it still
  has more than one active child process after 5 seconds.
* tearDownModule() now checks for dangling processes and threads
  before sleep 500 ms. And it now only sleeps if there is a least one
  dangling process or thread.
