Followup of 94739085.

key()-based sorting is now used instead, available since Python 2.4.

Jupyter integration is more or less abandoned. Just do the minimum to make tests pass.

Also, remove `if True/1/False/0` statement raising pylint warnings.

* Zope API changes:
  + publish():
    - stdin is now BytesIO rather than StringIO.
    - Returned value of a script is passed to str() in python2, not in python3 anymore.
  + HTTPResponse `body` property is now bytes().
  + OFS.Image.File file parameter is bytes().
  + zope.interface implements() is now @implementer decorator.
  + Python standard logging module recommended instead of zLOG.
* Python3 API changes:
  + builtin reduce() was removed.
  + urlnorm is now available.
  + Use BytesIO rather than StringIO to follow py3 API.
  + hmac.new() requires digestmod argument from Python 3.8.
  + Use six.moves library to handle moved objects from py2 to py3.
  + `modernize -f xrange_six` then slightly adjusted manually to just use range
     where it does not make a significant difference (for example in test).
  + base64.b64encode() now expects bytes().
  + UserDict() interface changed:
    - New parameter in update() and pop().
    - `failobj` setdefault parameter renamed to `default`.
  + ensure_list() on dict.{values,items}() and list(dict) for dict.keys() when
    we really need a list and not an iterable (Python3).
  + Make dict iteration works on both version of Python.
    - Use six.iter{items,values,keys}().
    - has_key() has been removed.
    - Make sure that dict.{items,values,keys}() returns a real list when
    modified (ensure_list()).
  + Comparisons between int and NoneType raises TypeError.
    + BTrees key must be str() not int() (_getOb()).
  + No more unbound methods in python3 so use six.get_unbound_function().
  + Exceptions:
    - No longer behave as sequences. Using `args` attribute instead.
    - When an exception has been assigned using `as target`, it is cleared at
      the end of the except clause.
  + file: py2 was returning `str` upon reading, now it returns text strings.
    Also, opening mode is text strings by default.
  + Data strings are bytes().
    - Replace str() by bytes().
  + iterators no longer have next() method, instead there is next() builtin.
  + New ConnectionError exception so rename existing one to not clash.
  + Integer division is now with //.
  + __nonzero__ is now __bool__.
  + apply() does not exist anymore.
  + Deprecated threading.Thread isAlive() has been removed.
  + im_func replaced by __func__.
  + Use six.with_metaclass() to define metaclass in a cross-compatible way with py2 and py3.
  + Only test method can be marked as expectedFailure(), not assert statement anymore.
  + os.path.walk() removed.
  + HTMLParser never fails: no strict mode nor HTMLParseError anymore (Python #15114).
  + Unpickler.find_global() is now Unpickler.find_class().

some conversion (TextDocument) depend on the content type, so it's
necessary to first update the content type before trying to convert to
base format

zope5: Since 5.8.1 missing Content-Type HTTP header is interpreted as application/x-www-form-urlencoded.

Zope.git:
  commit 5b324f6c461f5ea1cc069739b6c32a1a5ff59df9
  Date:   Thu Jan 19 07:15:18 2023 +0100
    replace `cgi.FieldStorage` by `multipart` (#1094)
    * interpret a missing `CONTENT_TYPE` as `application/x-www-form-urlencoded`

With cgi.FieldStorage, it was interpretated as text/plain so Content-Type has to
be provided now (even for WebDAV despite RFC 4918 stating that it *SHOULD* be
provided).

Some Unit Tests did not provide such header at all but this was wrong (such as
erp5_stripe:testStripe where the real request has application/json as
Content-Type and not text/plain).

This is follow up of commit 0000dee0 (erp5_core: update
mimetypes_registry with shared-mime-info_2.4-5 and media-types_10.1.0.,
2024-09-17), after this change, Products.MimetypesRegistry build regular
expressions with fnmatch.translate, which on python2 produces regular
expressions like:

     >>> fnmatch.translate('*.aaa')
     '.*\\.aaa\\Z(?ms)

such expressions cause a warning in python3:

    >>> re.compile('.*\\.aaa\\Z(?ms)')
    ...
    re.error: global flags not at the start of the expression at position 9

Running this on python3 would be incompatible with python2, because
`fnmatch.translate` on python3 generates regular expressions that are not
valid on python2.

To solve this mimetypes_registry.xml was edited by hand to move the
flags at the beginning, replacing for example '.*\\.aaa\\Z(?ms)' by
'(?ms).*\\.aaa\\Z'

The ssl/x509 were renamed after we decided to change the name of the
holding property sheet during the code review. The code was updated,
but not this form

  Otherwise it gets other unrelated objects from a full text search

This is tested in test_14_multiple_workflow_different_permission_roles

See merge request !1982

Otherwise
  https://example.com/foo
would match
  https://example.com/
but not the language-selector
  https://example.com/en/

and not as manager, as some scripts in the workflow have proxy roles, so
it would be nice to test them too.

The CA certificate can be stored on the connector (it is obtained from
the clammit instance).

To store properties related to x509 certificates, used for exemple in
TLS connections

When commiting from ERP5, they are always alphabetically ordered.
So commit the list of property sheets ordered alphabetically to ease to decrease
the number of diffs when commiting from ERP5.

   Fix inconsistency on guard and permissions

   Fixup the inconsistent restart/restart_action transition, that has
     Assignee/Assignor guard in am inconsistent matter.

   Allow assignor have the same permissions and guard than the assignee

   Fix up permissions on delivered state, where the Assignor had no
   permission to view/access accounting period (so deliver by assignor
   only was impossible).
