The module-global screen_encoding stored a borrowed pointer to the
encoding owned by the window returned by the first initscr() call. That
window can be deallocated while unctrl() and ungetch(), which have no window
of their own, still use the pointer to encode non-ASCII characters.
Keep a private copy of the encoding instead.

Add curses tests for panels, textpad, and window behavior
Extend test_curses with behavior-verifying tests that go beyond the
existing smoke tests:
* curses.panel stacking: new_panel/top/bottom/above/below ordering,
hide/show/hidden, move, replace and userptr round-trip.
* Real-window curses.textpad.Textbox: gather(), edit(), stripspaces,
insert mode and the Emacs-like editing commands (previously only
exercised through a MagicMock).
* Window output: addstr cursor advance and addnstr truncation,
insstr/insnstr shifting without cursor movement, and pad behavior
(instr, subpad cell sharing, the required 6-argument refresh()).
* Error handling: out-of-range coordinates raising curses.error and
bad character/string argument types.

Replace the previously sparse reference documentation with full coverage of
the public API of the tkinter package, written from the Tcl/Tk manual pages,
the existing documentation and the module docstrings.
* Doc/library/tkinter.rst gains a "Reference" section documenting every public
class, method, function and constant of the core module -- the widgets, the
Misc, Wm, Pack, Place, Grid, XView and YView mix-ins, the Variable and image
classes, the module-level functions and the symbolic constants.
* Doc/library/tkinter.ttk.rst, dialog.rst, tkinter.font.rst and the other
module pages document their remaining classes, methods and functions.
The descriptions are Python-oriented (correct return types -- tuples rather
than Tcl lists, booleans, integers, None on cancellation, and so on) and were
checked against the Tcl/Tk 9.1 manual pages and the implementation.
versionadded, versionchanged and deprecated directives are added for the
public API, determined from the git history relative to Python 3.0: the
tkinter.ttk module (3.1); the Text, Wm, Menu and Misc methods exposing Tk 8.5
features (3.3); and the many later additions and behavior changes up to 3.15.
The Tk version required by features added after Tk 8.6 is noted as well. The
bundled Tcl/Tk version is updated to 9.0 and the manual-page links point at
the tcl9.0 reference.

wm_attributes positional-argument deprecation to 3.13, and update the
bundled Tcl/Tk version to 8.6.

gh-151519: Check effective gid in `_test_all_chown_common` group-0 guard (GH-151521)
The guard that skips the "chown to gid 0 should fail" assertion used
only `os.getgroups()` (supplementary groups). The kernel also accepts
the effective/filesystem gid for chown, so when a process runs with
egid 0 and a non-zero uid (common in containers and user namespaces),
chown(-1, 0) succeeds and the assertion spuriously fails.
Add an `os.getegid() != 0` check alongside the existing
`0 not in os.getgroups()` guard.

Reporting the exit codes of processes that died without a known cause

exception instead of one shared instance.

gh-143988: Fix re-entrant mutation crashes in socket sendmsg/recvmsg_into (#143987)
Fix crashes in socket.sendmsg() and socket.recvmsg_into() that could
occur if buffer sequences are mutated re-entrantly during argument
parsing via __buffer__ protocol callbacks.
The bug occurs because:
1. PySequence_Fast() returns the original list object when the input
is already a list (not a copy).
2. During iteration, PyObject_GetBuffer() triggers __buffer__
callbacks which may clear the list.
3. Subsequent iterations access invalid memory (heap OOB read).
The fix replaces PySequence_Fast() with PySequence_Tuple() which
always creates a new tuple, ensuring the sequence cannot be mutated
during iteration.

[3.14] gh-89554: Document socket.SocketType as a class (#150683) (#151245)
gh-89554: Document socket.SocketType as a class (#150683)
socket.SocketType is a class (re-exported from _socket as an alias of
_socket.socket, the base class of socket.socket), but was documented with
the ".. data::" directive, so ":class:" cross-references to it cannot
resolve against a py:class target.
Switch the entry to ".. class::", correct the misleading description
(SocketType is the base class of the socket type, not "type(socket(...))"
which is socket.socket; addresses gh-88427), move it into the Socket
Objects section, and document the socket object methods and attributes
nested under the socket class, dropping the redundant "socket." prefix.
Backport to 3.13: Replace ":platform: Windows" with
".. availability:: Windows" in ioctl() method.
