* Revert "bpo-45173 Remove configparser deprecations"

This reverts commit df2284b.

* bpo-45173: Note these configparser deprecations will be removed in 3.12

After GH-15623 deleted `generrmap.c`, a related mak-file stopped working. The mak contains generrmap-related rules only so it should be removed altogether.

Further search for `errmap\.mak|generrmap` regex through content of CPython files shows no dangling reference left.

Since generrmap is already effectively removed, this pull request contains no blurp.

Per Pitrou:

> The original intent for the “accessor” thing was to have a variant that did all accesses under a filesystem tree in a race condition-free way using openat and friends. It turned out to be much too hairy to actually implement, so was entirely abandoned, but the accessor abstraction was left there.

https://discuss.python.org/t/make-pathlib-extensible/3428/2

Accessors are:

- Lacking any internal purpose - '_NormalAccessor' is the only implementation
- Lacking any firm conceptual difference to `Path` objects themselves (inc. subclasses)
- Non-public, i.e. underscore prefixed - '_Accessor' and '_NormalAccessor' 
- Unofficially used to implement customized `Path` objects, but once once [bpo-24132]() is addressed there will be a supported route for that.

This patch preserves all existing behaviour.

The heredoc creation statements use >> to append conftest.c.  This can cause
tricky build issues if the file is not correctly removed prior to its
name being reused (such name is reused several times for different
contextual tests during the build).  One such result from appending may
cause #include <ac_nonexistent.h> to persist when testing to acquire
PLATFORM_TRIPLET.  This can then lead to downstream issues concerning SOABI.

test_ftplib now silently ignores socket errors to prevent logging
unhandled threading exceptions.

@pablogsal, sorry i failed to rebase to main, so i recreated #22190 (comment)

> PyRun_InteractiveOne\*() functions allow to explicitily set fd instead of stdin.
but stdin was hardcoded in readline call.

> This patch does not fix target file for prompt unlike original bpo one : prompt fd is unrelated to tokenizer source which could be read only. It is more of a bugfix regarding the docs :  actual documentation say "prompt the user" so one would expect prompt to go on stdout not a file for both PyRun_InteractiveOne\*() and PyRun_InteractiveLoop\*().

Fix test_gdb.test_pycfunction() for Python built with clang -Og.
Tolerate inlined functions in the gdb traceback.

When _testcapimodule.c is built by clang -Og, _null_to_none() is
inlined in meth_varargs() and so gdb returns _null_to_none() as
the frame #1. If it's not inlined, meth_varargs() is the frame #1.

The gevent project is using the two `PyThreadState` fields I renamed in gh-30590.  This PR fixes the names.  See #msg412046.

Fix the test checking if the C compiler supports -Og option in the
./configure script to also use -Og on clang which supports it.

This adds a slightly more detailed explanation of the change.
The most important point is that the changed/removed fields
were "subject to change" to begin with.

* bpo-46542: test_lib2to3 uses support.infinite_recursion()

Fix a Python crash in test_lib2to3 when using Python built in debug
mode: limit the recursion limit.

The test_all_project_files() test of test_lib2to3 now uses the
test.support.infinite_recursion() context manager when processing the
infinite_recursion.py file to prevent a crash when Python is built in
debug mode.

The two test_all_project_files() tests now use subTest() and log the
refactored/parsed filename (if test_lib2to3 is run in verbose mode).

* Update Lib/lib2to3/tests/data/infinite_recursion.py

musl libc and gnu libc are not ABI compatible so we need set different
SOABI for musl and not simply assume that all linux is linux-gnu.

Replace linux-gnu with the detected os for the build from config.guess
for linux-musl*.
