This is an unrevert of d58ebf0 (gh-119636), which was reverted by 9216a53 (gh-119639) due to problems which have been resolved.
This is minimal support for multiphase init. Subinterpreters are not supported yet. That will be addressed in a later change.

GH-119169: Implement `pathlib.Path.walk()` using `os.walk()` (GH-119573)
For silly reasons, pathlib's generic implementation of `walk()` currently
resides in `glob._Globber`. This commit moves it into
`pathlib._abc.PathBase.walk()` where it really belongs, and makes
`pathlib.Path.walk()` call `os.walk()`.

GH-89727: Partially fix `shutil.rmtree()` recursion error on deep trees (GH-119634)
Make `shutil._rmtree_unsafe()` call `os.walk()`, which is implemented
without recursion.
`shutil._rmtree_safe_fd()` is not affected and can still raise a recursion
error.

The deadlock only affected the free-threaded build and only occurred
when the GIL was enabled at runtime. The `Py_DECREF(old_name)` call
might temporarily release the GIL while holding the type seqlock.
Another thread may spin trying to acquire the seqlock while holding the
GIL.
The deadlock occurred roughly 1 in ~1,000 runs of `pool_in_threads.py`
from `test_multiprocessing_pool_circular_import`.

gh-119661: Add _Py_SINGLETON() include in Argumenet Clinic (#119712)
When the _Py_SINGLETON() is used, Argument Clinic now adds an
explicit "pycore_runtime.h" include to get the macro. Previously, the
macro may or may not be included indirectly by another include.

The fix in gh-119561 introduced an assertion that doesn't hold true if any of the three new test extension modules are loaded more than once. This is fine normally but breaks if the new test_check_state_first() is run more than once, which happens for refleak checking and with the regrtest --forever flag. We fix that here by clearing each of the three modules after loading them. We also tweak a check in _modules_by_index_check().

The assertion was added in gh-118532 but was based on the invalid assumption that PyState_FindModule() would only be called with an already-initialized module def. I've added a test to make sure we don't make that assumption again.

gh-111997: Fix argument count for LINE event and clarify type of argument counts. (GH-119179)
(cherry picked from commit 70b07aa415)
Co-authored-by: scoder <stefan_ml@behnel.de>
`Out-File -Encoding utf8` and similar commands in Windows Powershell 5.1 emit
UTF-8 with a BOM marker, which the regular `utf-8` codec decodes incorrectly.
`utf-8-sig` accepts a BOM, but also works correctly without one.
This change also makes .pth files match the way Python source files are handled.

gh-69214: Fix fcntl.ioctl() request type (GH-119498)

parameter of fcntl.ioctl() to support requests larger than UINT_MAX.

gh-119461: Fix ThreadedVSOCKSocketStreamTest (#119465)
Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host
address or the "any" address, use the local communication address
(loopback): VMADDR_CID_LOCAL.
On Linux 6.9, apparently, the /dev/vsock device is now available but
get_cid() returns VMADDR_CID_ANY (-1).
(cherry picked from commit e94dbe4ed8)
`drop_gil()` assumes that its caller is attached, which means that the current
thread holds the GIL if and only if the GIL is enabled, and the enabled-state
of the GIL won't change. This isn't true, though, because `detach_thread()`
calls `_PyEval_ReleaseLock()` after detaching and
`_PyThreadState_DeleteCurrent()` calls it after removing the current thread
from consideration for stop-the-world requests (effectively detaching it).
Fix this by remembering whether or not a thread acquired the GIL when it last
attached, in `PyThreadState._status.holds_gil`, and check this in `drop_gil()`
instead of `gil->enabled`.
This fixes a crash in `test_multiprocessing_pool_circular_import()`, so I've
reenabled it.
