…umentation (pythonGH-156822) (pythonGH-156853)

Corrected, in the documentation and in the docstrings:

* GetInputContext() returns bytes, and its result extends to the end of the
  buffered input;
* Parse() accepts a bytes-like object as well as a string, and ignores the
  encoding declaration for a string;
* ParseFile() only supports binary files;
* XML_ERROR_XML_DECL was described as XML_ERROR_NO_ELEMENTS;
* UnparsedEntityDeclHandler is not restricted to Expat 1.2;
* GetSpecifiedAttributeCount() needs ordered_attributes.

Documented the intern parameter and attribute, namespace_prefixes,
SkippedEntityHandler, XML_CTYPE_MIXED and XML_CTYPE_NAME, and EXPAT_VERSION,
version_info and features.

Removed obsolete notes about Expat 1.2 and 1.95.0, and :noindex: from the
content model constants, which are not documented elsewhere; completed the
list of attribute types in AttlistDeclHandler.
(cherry picked from commit d16a691)

…XMLGenerator (pythonGH-156799) (pythonGH-156857)

The namespace declarations were the only attribute values written without
quoteattr(), so a URI containing "&", "<" or a quote character produced a
document which cannot be parsed.

…ion (pythonGH-156354) (pythonGH-156873)

window.encoding does not encode the string arguments on a build with
wide-character support: the curses library converts the characters itself.

In the HOWTO: getch() returns -1, not curses.ERR, when there is no input,
and half-delay mode does the same as no-delay mode.  getkey() returns the
key name only for a special key.  leaveok() is not a synonym for curs_set().
getstr() returns a bytes object, interprets the erase and kill characters,
and limits bytes.  The ACS_* constants are not all larger than 255.
Also document get_wch() before getch(), and read whole characters in the
example.

For the `atexit` module:

- Move common info from `register` to the module level (a lot of this
  was duplicated -- less maintainable and harder to read)
- Use *interpreter shutdown* consistently, introducing it as a more
  general term for the old docs' *program termination*.
- Use the term *exit handler* consistently
- Move warning for a mitigated footgun to a change entry
- Add a new warning about keeping things usable

Similarly clarify docs for the `atexit` attribute in `weakref`.

[3.15] pythongh-156002: Bound zipfile decompression for bzip2/LZMA/Zstandard (pythonGH-156003) (pythonGH-156362)

Patch by @tonghuaroot.

zipfile.ZipExtFile._read1() bounds the output of each decompress() call
for DEFLATE members by passing a max_length to zlib, but for bzip2, LZMA,
and Zstandard members it called decompress() with no bound. A whole
compressed chunk was therefore expanded into a single allocation before
the data[:self._left] clip ran, so a consumer that deliberately reads in
small chunks to limit memory (for example zf.open(name).read(8192)) was
silently unprotected for non-DEFLATE members. A small, spec-conformant
archive member declaring a large uncompressed size could drive multi-GB
peak memory.

_read1() now passes a per-call bound to the non-DEFLATE decompress()
(mirroring the DEFLATE branch) and drains the decompressor's internal
buffer across calls by checking needs_input before reading more
compressed input. zipfile's LZMADecompressor wrapper forwards max_length
and exposes needs_input so the bound also holds for LZMA members.

…b.run import (pythonGH-156915) (python#156959)

pythongh-156896: Stop scrubbing tkinter submodules upon idlelib.run import (python#156915)

Instead, invoke the scrubbing within run.main, which is called after
the import when starting the IDLE user process.

To manually test that scrub_tkinter_submodules
is called when proper, start (or restart) Shell, enter
`import tkinter; dir(tkinter), and check that that font,
messagebox, ttk, and the dialog modules are missing.

It is obvious from the code that the function is not otherwise
called.  To test anyway, continue with `import tkinter.ttk;
import idlelib.run; tkinter.ttk` and check for proper output.
