[3.14] gh-151949: Fix Sphinx reference warnings in `Doc/library/lzma.rst` (GH-153878) (#154125)
* gh-151949: Fix Sphinx reference warnings in `Doc/library/lzma.rst` (GH-153878)
The lzma module constants (FORMAT_*, CHECK_*, PRESET_*, FILTER_*, MODE_*
and MF_*) were referenced with the :const: role throughout the module
documentation but were never defined as reference targets, producing
"reference target not found" warnings under nitpicky mode.
Document these public constants with .. data:: directives, following the
convention used by the signal, socket and ssl modules, so the existing
references resolve. The now-redundant inline descriptions of the format
and check constants are condensed into linked references.

[3.14] gh-154399: Fix venv activate.csh in a non-interactive shell (GH-154400) (GH-154409)
activate.csh saved the prompt unconditionally, but the prompt variable
only exists in interactive shells, and csh fails on an undefined
variable.

[3.14] gh-154427: Check the access time in UtimeTests only if it is stored (GH-154428) (GH-154433)
HAMMER2 on DragonFly BSD does not store the access time and os.stat()
returns the modification time instead. Probe the file system, like it
is already done for the timestamp resolution.

gh-153741: Harden IDLE GUI tests for newer Tk and display scaling (GH-153742)
In test_sidebar.test_mousewheel, only use the X11 <Button-4>/<Button-5> events when testing on
x11 Tk before 8.7. Otherwise, use <Mousewheel> as on other systems.
In test_configdialog, assert the 'disabled' state flag alone instead of
the exact ttk state tuple (which transient pointer states break), and
restore the tests' method masks with addCleanup().

[3.14] gh-154366: Fix test_asyncio.test_sendfile timing out on DragonFly BSD (GH-154367) (GH-154372)
A 4 KiB receive buffer makes DragonFly defer every window update to the
delayed ACK timer, so each buffer worth of data costs 100 ms. Use a
larger socket buffer there; it is still small enough to pause the
protocol long before all data is sent.

[3.14] gh-154345: Fix test_posix_pty_functions() killing the worker on Solaris (GH-154346) (GH-154355)
Pushing the "ptem" STREAMS module makes a session leader without a
controlling terminal acquire the slave as one, so closing the file
descriptors sent SIGHUP to the session and killed the regrtest worker.
Disown it after the pushes, as os.openpty() does.

OpenBSD. Worker processes are started in their own session, so the

fails with EISDIR (IsADirectoryError) instead of EPERM, so the cleanup did
not reset the flags. Handle IsADirectoryError the same as PermissionError.

being modified or removed. Clear the flags before removing, so cleaning

On DragonFly BSD setsockopt(IPPROTO_IPV6, IPV6_V6ONLY, 0) succeeds without
actually clearing the flag, so has_dualstack_ipv6() wrongly returned True.

[3.14] gh-153864: Fix curses window.insch() for non-ASCII characters on a wide build (GH-153865) (GH-154152)
On a wide build, winsch() does not locale-decode a byte above 127, unlike
waddch(), so insch()/mvinsch() stored the wrong character for a non-ASCII
byte of an 8-bit locale ('€' 0xA4 under ISO-8859-15 became U+00A4 '¤').
Decode the byte with btowc() and insert it as a wide character, as addch()
effectively does.

ImportError, ValueError or UnicodeEncodeError, depending on the

[3.14] gh-153862: Fix curses window.inch() for non-ASCII characters on a wide build (GH-153863) (GH-154151)
On a wide build, winch() returns the low 8 bits of the character's code
point with no locale conversion, so inch()/mvinch() disagreed with instr()
for a non-ASCII character of an 8-bit locale ('€' under ISO-8859-15 gave
0xAC instead of 0xA4). Re-encode the cell to its locale byte via wctob(),
as ncurses does for getbkgd().

gh-153926: Fix documented parameter name for `calendar.calendar` and `calendar.prcal` (GH-153927)
gh-153926: Fix documented parameter name for calendar.calendar and calendar.prcal
calendar.calendar() and calendar.prcal() are bound methods of the
module's TextCalendar instance, whose first parameter is named theyear,
but the documentation named it year, so the documented keyword raised
TypeError. Update the documentation to match the real signature, which
also matches the sibling month() and prmonth() functions.

[3.14] gh-151644: Fix data race in sys.setdlopenflags/getdlopenflags under free-threading (gh-151768) (gh-153789)
In free-threading builds, concurrent calls to sys.getdlopenflags() and
sys.setdlopenflags() race on interp->imports.dlopenflags. Fix by
using FT_ATOMIC_LOAD_INT_RELAXED / FT_ATOMIC_STORE_INT_RELAXED in
_PyImport_GetDLOpenFlags and _PyImport_SetDLOpenFlags, consistent with
how analogous interpreter-state integer fields (lazy_imports_mode,
pystats_enabled) are protected.
Relaxed ordering is correct here: dlopenflags is a standalone config
integer with no ordering relationship to other memory.

* Modernize the tkinter.ttk front matter and its Tcl/Tk links, and add
