gh-107396: tarfiles: set self.exception before _init_read_gz() (GH-107485)
In the stack call of: _init_read_gz()
```
_read, tarfile.py:548
read, tarfile.py:526
_init_read_gz, tarfile.py:491
```
a try;except exists that uses `self.exception`, so it needs to be set before
calling _init_read_gz().

Such C API functions as PyErr_SetString(), PyErr_Format(),
PyErr_SetFromErrnoWithFilename() and many others no longer crash or
ignore errors if it failed to format the error message or decode the
filename. Instead, they keep a corresponding error.

* gh-107715: Escape class name in regular expression (GH-107716)
This patch escapes the class name before embedding it in the regular expression
for `pat` in `doctest.DocTestFinder._find_lineno`. While class names do not
ordinarily contain special characters, it is possible to encounter these when a
class is created dynamically. Escaping the name will correctly return `None` in
this scenario, rather than potentially matching a different class or raising
`re.error` depending on the symbols used.

gh-99203: shutil.make_archive(): restore select CPython <= 3.10.5 behavior (GH-99802)
Restore following CPython <= 3.10.5 behavior of shutil.make_archive()
that went away as part of gh-93160:
Do not create an empty archive if root_dir is not a directory, and, in
that case, raise FileNotFoundError or NotADirectoryError regardless
of format choice. Beyond the brought-back behavior, the function may
now also raise these exceptions in dry_run mode.

* 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..

gh-107471: Fix Refleaks in test_import (gh-107569)
gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module.
The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests.
(This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)
