The non-ASCII tests only exercised what the runner's locale could encode (in
practice UTF-8). Add 8-bit-encoding cases to the character and string I/O
tests, each guarded by the existing encodability check: ASCII, a character
common to the Latin encodings ('é'), and ones distinctive to a single encoding
(byte 0xA4 is '¤' in ISO-8859-1, '€' in ISO-8859-15, 'є' in KOI8-U). Run the
whole suite under different locales to cover them; unrepresentable cases skip.
* gh-152415: Verify character output round-trips in test_output_character
Read each written character back with in_wch() or instr() rather than
inch(), which on a wide build returns the low byte of the code point
instead of the locale-encoded byte and so mangles a non-ASCII character
of an 8-bit locale. This lets the int-argument cases cover '€'/'є', and
adds matching coverage for the str argument.
insch() with an int byte > 127 is checked only for Latin-1: on a wide
build ncurses winsch stores a printable byte directly as a code point
instead of decoding it through the locale.

Textbox.edit() ignored typing in the lower-right cell of the window. It is
now written with insch(), which fills the cell without moving the cursor out
of the window (addch() there raises an error and scrolls a scrollable window).

(cherry picked from commit 671357691f)
Co-authored-by: stratakis <cstratak@redhat.com>
A command created with createcommand() held a strong reference to the
interpreter, forming an uncollectable cycle (interpreter -> command ->
interpreter) that kept the interpreter and the callback alive until the
command was removed with deletecommand() or destroy(). The command now
borrows the reference; it cannot outlive the interpreter, which deletes its
commands when finalized.

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.
