Run test_shelve with all underlying dbm implementations and pickle protocols.
Also make test_shelve discoverable.

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.

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.

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.

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..

* 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* Remove some outdated code and comments..

They support now splitting escape sequences between input chunks.
Add the third parameter "final" in codecs.raw_unicode_escape_decode().
It is True by default to match the former behavior.

PyFile_NewStdPrinter() does crash if the argument is not 1 or 2.
Fix also a few pyflakes warnings: remove unused import and variables.
