signal.setitimer() may disable the timer when passed a tiny value.
Tiny values (such as 1e-6) are valid non-zero values for setitimer(), which

platform, our conversion routine could convert 1e-6 into a zero interval,
therefore disabling the timer instead of (re-)scheduling it.

Convert IDLE's built-in 'extensions' to regular features.
About 10 IDLE features were implemented as supposedly optional extensions.
Their different behavior could be confusing or worse for users and not good
for maintenance.  Hence the conversion.
The main difference for users is that user configurable key bindings for
builtin features are now handled uniformly.  Now, editing a binding in a
keyset only affects its value in the keyset.  All bindings are defined
together in the system-specific default keysets in config-extensions.def.
All custom keysets are saved as a whole in config-extension.cfg.  All take
effect as soon as one clicks Apply or Ok.
The affected events are '<<force-open-completions>>', '<<expand-word>>',
'<<force-open-calltip>>', '<<flash-paren>>', '<<format-paragraph>>',
'<<run-module>>', '<<check-module>>', and '<<zoom-height>>'.  Any (global)
customizations made before 3.6.3 will not affect their keyset-specific
customization after 3.6.3. and vice versa.
Initial patch by Charles Wohlganger.

IDLE -- Factor a VarTrace class out of ConfigDialog.
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%.

IDLE - Improve configdialog font page and tests.
In configdialog: Document causal pathways in create_font_tab docstring.
Simplify some attribute names. Move set_samples calls to var_changed_font
(idea from Cheryl Sabella).  Move related functions to positions after the
create widgets function.
In test_configdialog: Fix test_font_set so not order dependent.  Fix renamed
test_indent_scale so it tests the widget.  Adjust tests for movement of
set_samples call.  Add tests for load functions.  Put all font tests in one
class and tab indent tests in another.  Except for two lines, these tests
completely cover the related functions.

gdb integration commands (py-bt, etc.) work on optimized shared builds now,
too.  :pep:`523` introduced _PyEval_EvalFrameDefault which inlines
PyEval_EvalFrameEx on non-debug shared builds.  This broke the ability to
use py-bt, py-up, and a few other Python-specific gdb integrations. The
problem is fixed by only looking for _PyEval_EvalFrameDefault frames in
python-gdb.py.  Original patch by Bruno "Polaco" Penteado.
