The term `Immutable` in the `sequence` entry of the glossary is used incorrectly, in fact dicts accepts hashable keys, which is not the same as immutable.
Lower the C recursion limit for HPPA, PPC64 and SPARC, as they use
relatively large stack frames that cause e.g. `test_descr` to hit
a stack overflow. According to quick testing, it seems that values
around 8000 are max for HPPA and PPC64 (ELFv1 ABI) and 7000 for SPARC64.
To keep things safe, let's use 5000 for PPC64 and 4000 for SPARC.

https://github.com/python/cpython/issues/88496 replaced text.update with text.update_idletasks in colorizer.py and outwin.py to fix test failures on macOS. While theoretically correct, the result was Shell freezing when receiving continuous short strings to print. Test: `while 1: 1`.
The guess is that there is no idle time in which to do the screen update. Reverting the change in one of the files,
outwin, fixes the issue. Colorizer runs ever 1/20 second and seems to work fine.
When running test-outwin on macOS, alias 'update'
to 'update_idletasks on the text used for testing.
Add a helper function that checks whether the test suite is running
inside a systemd-nspawn container, and skip the few tests failing
with `--suppress-sync=true` in that case. The tests are failing because
`--suppress-sync=true` stubs out `fsync()`, `fdatasync()` and `msync()`
calls, and therefore they always return success without checking for
invalid arguments.
Call `os.open(__file__, os.O_RDONLY | os.O_SYNC)` and check the errno to
detect whether `--suppress-sync=true` is actually used, and skip
the tests only in that scenario.
Debian (and derivatives) provide a /usr/bin/pager binary, managed by the
alternatives system, that always points to an available pager utility.
Allow _pyrepl to use it, to follow system policy.
This is a very trivial change, from a patch that Debian has been
carrying since 2.7 era. Seems appropriate to upstream.

Multiple places in the I/O stack optimize common cases by using the
information from stat. Currently individual members are extracted from
the stat and stored into the fileio struct. Refactor the code to store
the whole stat struct instead.
Parallels the changes to _io. The `stat` Python object doesn't allow
changing members, so rather than modifying estimated_size, just clear
the value.
