* Strings with length from 2**31-1 to 2**32-2 always caused MemoryError,
it doesn't matter how much memory is available.
* Strings with length exactly 2**32-1 caused OSError.
* Strings longer than 2**32-1 characters were truncated due to integer overflow bug.
* Strings containing the null character were truncated at the first null character.
Now strings longer than 2**31-1 characters caused OverflowError and the null character is allowed.
Move the "deprecated positinal" tests from clinic.test.c to
_testclinic.c. Mock PY_VERSION_HEX in order to prevent generated
compiler warnings/errors to trigger. Put clinic code for deprecated
positionals in Modules/clinic/_testclinic_depr_star.c.h for easy
inspection of the generated code.

It did not work in the case of a subpattern containing backtracking.
Temporary implement possessive quantifiers as equivalent greedy qualifiers
in atomic groups.
Extract helper methods for formatting the signature and parameter
sections, and clean up the remaining function body.

- The `dump_stack()` method could call a `__repr__` method implemented in Python,
causing (infinite) recursion.
I rewrote it to only print out the values for some fundamental types (`int`, `str`, etc.);
for everything else it just prints `<type_name @ 0xdeadbeef>`.
- The lltrace-like feature for uops wrote to `stderr`, while the one in `ceval.c` writes to `stdout`;
I changed the uops to write to stdout as well.
- Generalize the syntax for the type of a stack effect to allow a trailing `*`,
so we can declare something as e.g. `PyCodeObject *`.
- When generating assignments for stack effects,
the type of the value on the stack should be the default (i.e., `PyObject *`)
even when the variable copied to/from it has a different type,
so that an appropriate cast is generated
However, not when the variable is an array --
then the type is taken from the variable (as it is always `PyObject **`).
This is a follow-up to gh-107567 and gh-107733.
We skip test_basic_multiple_interpreters_deleted_no_reset on tracerefs builds. The test breaks interpreter isolation a little, which doesn't work well with Py_TRACE_REFS builds, so I feel fine about skipping the test.
PEP 683 (immortal objects) revealed some ways in which the Python documentation has been unnecessarily coupled to the implementation details of reference counts. In the end users should focus on reference ownership, including taking references and releasing them, rather than on how many reference counts an object has.
This change updates the documentation to reflect that perspective. It also updates the docs relative to immortal objects in a handful of places.
