gh-126004: Remove redundant safeguards for codecs handlers tests (#127680)
We remove the safeguards that were added in `Lib/test/test_capi/test_codecs.py`
since they are now redundant (see 32e07fd377f81cbeb8c108fc791a3e7d631319b6
for additional context).
Indeed, the codecs handlers now correctly handle the `start` and `end` positions
of `UnicodeError` objects and thus should not crash.
gh-101410: support custom messages for domain errors in the math module (#124299)
This adds basic support to override default messages for domain errors
in the math_1() helper. The sqrt(), atanh(), log2(), log10() and log()
functions were modified as examples. New macro supports gradual
changing of error messages in other 1-arg functions.

gh-128902: Fix check for fallthrough attribute support (#128903)
Clang versions prior to 10 (which corresponds to Apple Clang 12) do not
support the GCC extension syntax __attribute__((fallthrough)), but do
evaluate __has_attribute(fallthrough) to 1 because they support the
C++11 style syntax [[fallthrough]]. The only way to tell if the GCC
style syntax is supported is thus to check the clang version.

GH-128520: Make `pathlib._abc.WritablePath` a sibling of `ReadablePath` (#129014)
In the private pathlib ABCs, support write-only virtual filesystems by
making `WritablePath` inherit directly from `JoinablePath`, rather than
subclassing `ReadablePath`.
There are two complications:
- `ReadablePath.open()` applies to both reading and writing
- `ReadablePath.copy` is secretly an object that supports the *read* side
of copying, whereas `WritablePath.copy` is a different kind of object
supporting the *write* side
We untangle these as follow:
- A new `pathlib._abc.magic_open()` function replaces the `open()` method,
which is dropped from the ABCs but remains in `pathlib.Path`. The
function works like `io.open()`, but additionally accepts objects with
`__open_rb__()` or `__open_wb__()` methods as appropriate for the mode.
These new dunders are made abstract methods of `ReadablePath` and
`WritablePath` respectively. If the pathlib ABCs are made public, we
could consider blessing an "openable" protocol and supporting it in
`io.open()`, removing the need for `pathlib._abc.magic_open()`.
- `ReadablePath.copy` becomes a true method, whereas `WritablePath.copy` is
deleted. A new `ReadablePath._copy_reader` property provides a
`CopyReader` object, and similarly `WritablePath._copy_writer` is a
`CopyWriter` object. Once GH-125413 is resolved, we'll be able to move
the `CopyReader` functionality into `ReadablePath.info` and eliminate
`ReadablePath._copy_reader`.

This fixes UBSan failures for the following objects:

- `CDataObject` and `CFieldObject`, and

On the default build, we convert the `LOCK_PTR` and `UNLOCK_PTR` macros to
functions with an unused parameter to ease "unused variable" compiler warnings
suppression. Finally, we also remove some redundant casts to `PyObject *`.
