Modify the ``EnumType.__dir__()`` and ``Enum.__dir__()`` to ensure
that user-defined methods and methods inherited from mixin classes always
show up in the output of `help()`. This change also makes it easier for
IDEs to provide auto-completion.
Rename PyConfig.no_debug_ranges to PyConfig.code_debug_ranges and
invert the value.
Document -X no_debug_ranges and PYTHONNODEBUGRANGES env var in
PyConfig.code_debug_ranges documentation.

* [bpo-43137](): webbrowser: Prefer gio open over gvfs-open
gvfs-open(1) was superseded by gio(1) in 2015, and removed from GNOME
releases in 2018. Debian and its derivatives like Ubuntu currently still
have a compatibility shim for gvfs-open, but we plan to remove it.
webbrowser prefers xdg-settings and xdg-open over gvfs-open, so this
will only have any practical effect on systems where the xdg-utils
package is not installed.
Note that we don't check for GNOME_DESKTOP_SESSION_ID before using gio.
gio does the right thing on any desktop environment that follows
freedesktop.org specifications, similar to xdg-settings, so it's
unnecessary to guard in this way. GNOME_DESKTOP_SESSION_ID was deprecated
in 2008 and removed from upstream gnome-session in 2018 (it's still
present in Debian/Ubuntu for backward compatibility, but probably
shouldn't be). The replacement way to detect a desktop environment is
the XDG_CURRENT_DESKTOP environment variable, which is a colon-separated
sequence where the first item is the current desktop environment and the
second and subsequent items (if present) are other desktop environments
that it resembles or is based on.
Resolves:
* [bpo-43137](): webbrowser: Never invoke gnome-open
gnome-open was part of GNOME 2, which was superseded in around 2010 and
is unmaintained. The replacement was gvfs-open, which was subsequently
replaced by gio(1) (as used in the previous commit).
* [bpo-43137](): webbrowser: Don't run gvfs-open on GNOME
gvfs-open was deprecated in 2015 and removed in 2018. The replacement
is gio(1) (as used in a previous commit).
GNOME_DESKTOP_SESSION_ID was deprecated in 2008 and removed in 2018.
The replacement is XDG_CURRENT_DESKTOP (as mentioned in a previous
commit).

To test this on a typical modern Linux system, it is necessary to disable the `xdg-settings` and `xdg-open` code paths, for example with this hack:

I haven't attempted to assess which of the specific web browsers such as Galeon are still extant, and which ones disappeared years ago. They could almost certainly be cleaned up, but that's beyond the scope of this PR.
* bpo-45514: Apply changes from importlib_resources@a3ef4128c6
* Mark legacy functions as deprecated in the docs and link to the migration docs in importlib_resources docs.
* Apply changes from importlib_resources@329ae9d5f2c.
* Indicate importlib.resources as a module.

* Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead.
* Add reference to function to frame, borrow references to builtins and globals.
* Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
Special handling is needed, because for non-slots dataclasses the instance attributes are not set: reading from a field just references the class's attribute of the same name, which contains the default value. But this doesn't work for classes using __slots__: they don't read the class's attribute. So in that case (and that case only), initialize the instance attribute. Handle this for both normal defaults, and for fields using default_factory.
Some of the tests in test_queue had a race condition in which a
non-sentinel value could be enqueued after the final sentinel value
leading to not all the inputs being processed (and test failures).
This changes feed() to enqueue a sentinel once the inputs are exhausted,
which guarantees that the final queued object is a sentinel. This
requires the number of feeder threads to match the number of consumer
threads, but that's already the case in the relevant tests.
Unlike the other locks reinitialized by _PyRuntimeState_ReInitThreads,
the "interpreters.main->id_mutex" is not freed by _PyRuntimeState_Fini
and should not force the default raw allocator.
