Some of the tests in test_queue had a race condition in which a
non-sentinel value could be enqueued after the final sentinel value
leading to not all the inputs being processed (and test failures).
This changes feed() to enqueue a sentinel once the inputs are exhausted,
which guarantees that the final queued object is a sentinel. This
requires the number of feeder threads to match the number of consumer
threads, but that's already the case in the relevant tests.

This PR fixes a bug in the 3.9 branch where
``functools.singledispatchmethod`` did not properly wrap attributes such as
``__name__``, ``__doc__`` and ``__module__`` of the target method. It also
backports tests already merged into the 3.11 and 3.10 branches in #29328 and
#29390.

the current test depended on integer sets being iterated on in a certain
fixed order. That order is different on PyPy (insertion based) and could
change in CPython in the future in theory. Make the test robust against
a different iteration order by sorting.

This commit fixes a bug in the 3.9 branch where 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)`. Tests for this scenario
were added to the 3.11 and 3.10 branches in #29034 and #29072; this commit
also backports those tests to the 3.9 branch.

The doctest module raised an error if a docstring contained an example that
attempted to access a classmethod property. (Stacking '@classmethod' on top of
`@property` has been supported since Python 3.9; see
https://docs.python.org/3/howto/descriptor.htmlGH-class-methods.)

An object implementing the os.PathLike protocol can represent a file
system path as a str or bytes object.
Therefore, _infer_return_type function should infer os.PathLike[str]
object as str type and os.PathLike[bytes] object as bytes type.

There are two errors that this commit fixes:
* 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..

NOTE: unlike the cherry-picked original, this commit points at a crazy location
due to a bug in the tokenizer that required a big refactor in 3.10 to fix.
We are leaving as-is for 3.9.
* 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..
