Also fix gh-139816: an exception raised in a callback no longer stops the
event loop to wait for Enter on a Python built without readline; pending
callbacks keep running until input is actually available on stdin.

gh-151497: Avoid huge pre-allocation for oversized tarfile extended headers (GH-151498)

tarfile reads a member's extended header (a GNU long name/link or a pax
header) with a single read sized by the header's size field:

    buf = tarfile.fileobj.read(self._block(self.size))

The size is taken from the archive and is not validated, so a ~512-byte
crafted file can claim several gigabytes (or, via base-256 encoding, far
more) and make read() pre-allocate that much memory -- on open/iterate,
before any extraction filter runs.

Read the extended-header data in bounded chunks instead, so an oversized
or truncated header can no longer force a huge allocation. The bytes
returned for valid archives are unchanged.

[3.15] gh-151693: Add curses tests for panels, textpad, and window behavior (GH-151694) (GH-151719)

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.

window can be deallocated while unctrl() and ungetch(), which have no window

Keep a private copy of the encoding instead.

gh-141510 Document and test frozendict class matching behaviour (GH-150799)

Frozendict has `_Py_TPFLAGS_MATCH_SELF` set so works correctly
with the single-arg class matching. However it isn't documented
in the list of classes this works with and it isn't tested.

The test is some way below the other similar tests but anything
else would need a large renumbering.
