`lchmod()`.

PyDict_Next no longer locks the dictionary in the free-threaded build. Locking
around individual PyDict_Next calls is not sufficient because the function
returns borrowed references and because it allows concurrent modifications
during the iteraiton loop.
The internal locking also interferes with correct external synchronization
because it may suspend outer critical sections created by the caller.
Moves the logic to update the type's dictionary to its own function in order
to make the lock scoping more clear.
Also, ensure that `name` is decref'd on the error path.
PyUnicode_FromFormat() no longer produces the ending \ufffd
character for truncated C string when use precision with %s and %V.
It now truncates the string before the start of truncated multibyte sequences.
The integer part of the timestamp can be rounded up, while the millisecond
calculation truncates, causing the log timestamp to be wrong by up to 999 ms
(affected roughly 1 in 8 million timestamps).
Add `pathlib.Path.copytree()` method, which recursively copies one
directory to another.
This differs from `shutil.copytree()` in the following respects:
1. Our method has a *follow_symlinks* argument, whereas shutil's has a
*symlinks* argument with an inverted meaning.
2. Our method lacks something like a *copy_function* argument. It always
uses `Path.copy()` to copy files.
3. Our method lacks something like a *ignore_dangling_symlinks* argument.
Instead, users can filter out danging symlinks with *ignore*, or
ignore exceptions with *on_error*
4. Our *ignore* argument is a callable that accepts a single path object,
whereas shutil's accepts a path and a list of child filenames.
5. We add an *on_error* argument, which is a callable that accepts
an `OSError` instance. (`Path.walk()` also accepts such a callable).

The tests are now passed with the current version of Tcl/Tk under
development (8.7b1+ and 9.0b3+).
The following changes were also made to make the tests more flexible:
* Helper methods like checkParam() now interpret the expected error message
as a regular expression instead of a literal.
* Add support of new arguments in checkEnumParam():
- allow_empty=True skips testing with empty string;
- fullname= specifies the name for error message if it differs from the
option name;
- sort=True sorts values for error message.
* Add support of the allow_empty argument in checkReliefParam():
allow_empty=True adds an empty string to the list of accepted values.
* Attributes _clip_highlightthickness, _clip_pad and _clip_borderwidth
specify how negative values of options -highlightthickness, -padx, -pady
and -borderwidth are handled.
* Use global variables for some common error messages.

This makes the following macros public as part of the non-limited C-API for
locking a single object or two objects at once.
* `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()`
* `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()`
The supporting functions and structs used by the macros are also exposed for
cases where C macros are not available.
