bpo-45583: Correct datamodel documentation of int() (GH-29182) (GH-29285)
It should be noted that this part of the documentation is redundant with
function.rst's documentation of int. This one was correctly updated with Python 3.8.

bpo-45436: Fix tkinter tests with Tcl/Tk 8.6.11+ (GH-29077) (GH-29080)
Since v8.6.11, a few configuration options seem to accept an empty value
where they did not previously; particularly the `type` of a `Menu`
widget, and the `compound` of any ttk widget with a label. Providing an
explicit expected error message to `checkEnumParam` bypasses the check
of an empty value, which no longer raises `TclError`.

bpo-39679: Add tests for classmethod/staticmethod singledispatchmethods (GH-29034) (GH-29072)
In Python 3.8 and 3.9, stacking `@functools.singledispatchmethod` on top of
`@classmethod` or `@staticmethod` caused an exception to be raised if the
method was registered using type-annotations rather than
`@method.register(int)`. This was not caught by unit tests, however, as the
tests only tested the `@method.register(int)` way of registering additional
implementations. The bug is no longer present in Python 3.10+, but
`test_functools.py` is still lacking regression tests for these cases. This
commit adds these test cases.

* The parser was not correctly computing the offset and the string
source for E_LINECONT errors due to the incorrect usage of strtok().
* The parser was not correctly unwinding the call stack when a tokenizer
exception happened in rules involving optionals ('?', [...]) as we
always make them return valid results by using the comma operator. We
need to check first if we don't have an error before continuing..

* Generate test classes at import time. It allows to filter them when
run with unittest. E.g: "./python -m unittest test.test_dbm.TestCase_gnu -v".
* Create a database class in a new directory which will be removed after
test. It guarantees that all created files and directories be removed
and will not conflict with other dbm tests.
* Restore dbm._defaultmod after tests. Previously it was set to the last
dbm module (dbm.dumb) which affected other tests.
* Enable the whichdb test for dbm.dumb.
* Move test_keys to the correct test class. It does not test whichdb().
* Remove some outdated code and comments..

bpo-45386: Handle strftime's ValueError graciously in xmlrpc.client (GH-28765) (GH-28934)
At import time, the xmlrpc.client module uses different date formats to
test strftime so it can format years with 4 digits consistently.
Depending on the underlying C library and its strftime implementation
some of these calls can result in ValueErrors, blocking the
xmlrpc.client module from being imported.
This commit changes the behavior of this bit of code to react to
ValueError exceptions, treating the format that caused them as an
non-viable option.

bpo-45353: Remind sys.modules users to copy when iterating. (GH-28842)
This is true of all dictionaries in Python, but this one tends to
catch people off guard as they don't realize when sys.modules might
change out from underneath them as a hidden side effect of their
code. Copying it first avoids the RuntimeError. An example when
this happens in single threaded code are codecs being loaded which
are an implicit time of use import that most need not think about.
