it's like 5.1, 2.4

This partially reverts 8a336dc5 (erp5_accounting: Allow
Assignor manage Accounting Periods, 2024-09-16) for the restart
transition, it is intentional that only Assignor can restart
an accounting period that have been closed.
The idea was to support a scenario where re-opening a period
that was closed can not be done directly by the Assignee but
needs validation from the assignor.

The check was made on the blob response type, which is set from the
Content-Type header returned by the server, but Safari has a different
interpretation of the charset parameter from the mime type, with a
content type set to application/json;charset=utf-8 like Base_redirect
does today, safari creates a blob with type application/json;charset=utf-8
and this was not detected as redirection and the json returned by
Base_redirect was downloaded. Fix this by checking only the essence
of the type.

This also revealed a potential problem when actually downloading json
files, in that case we also check that we have the X-Location header,
that is supposed to be set by Base_redirect before interpreting the json
and when it's not present we force download.

Follow up of ff624fd2 (ERP5Workflow: newly added permission should be
acquired for all existing states., 2024-11-04) and cbef6282 (ERP5Workflow:
make sure not create duplicate permissions, 2024-11-05)

Fix a problem introduced in ff624fd2 (ERP5Workflow: newly added
permission should be acquired for all existing states., 2024-11-04),
visible in a test failure

before, all permissions became acquired in all states once we update permission list.

This reverts commit 5e21f77f.

This was done too quickly based on a wrong assumption that simulation
movements to build would always be in planned state and that we could
have an efficient way of selecting them by catalog with index on
portal_type and simulation state, but it does not work this way.

Maybe the change is useful for something else, but since we don't have
any use case for now, let's just revert.

In 1b555dbf (py2/py3: Make Products code compatible with both python2
and python3 (!1751)., 2024-07-16) we changed the code in a
way that on python2 it would first node text to a python2 str and only
later convert it to unicode, but setting text to a str during the first
step can fail with:

    ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters

This change to set directly unicode on py2.

and move the implementation of SimulationMovement.getSimulationState
here. This makes it possible for rules to generate simulation movements
that are not necessary planned.

Applied rules must have a rule as specialise

`sender@customer.com <sender@customer.com>` used in the test is not a
valid email address. We have updated to python3.9.20 which comes with a
fix for CVE-2023-27043 and no longer allow this kind of broken addresses.

Replace the address with a similar valid address,
`"sender@customer.com" <sender@customer.com>`, that was probably the
original intention of this test.

On python3, the type of selected columns depend on the data type from
mariadb side, VARCHAR will be str, BINARY/BLOB will be bytes, etc

These SQL method select path that is first evaluated from a variable
that is NULL and in that case, mariadb seems to select LONGBLOB as data
type:

    MariaDB [test]> set @defined_as_null=null; drop table if exists tmp; create table tmp as (select @defined_as_null); show create table tmp;
    +-------+------------------------------------------------------------------------------------------------------------------------------------+
    | Table | Create Table                                                                                                                       |
    +-------+------------------------------------------------------------------------------------------------------------------------------------+
    | tmp   | CREATE TABLE `tmp` (
      `@defined_as_null` longblob DEFAULT NULL
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci |
    +-------+------------------------------------------------------------------------------------------------------------------------------------+

By casting to CHAR in SQL, on the python side we always have the str
that we expect here, because this is used as path attribute of a SQL
brain.

This is similar to 18deb716 (ProcessingNodeTestCase: also setRequest
in processing_node, 2023-05-02), as said in that commit message,
timerserver loop calls setRequest, but before entering the loop, we
wait for the portal to be created with:

 447   │           try:
 448   │             self.portal = self.app[self.app.test_portal_name]
 449   │           except (AttributeError, KeyError):
 450   │             continue

While accessing like this, this will load classes and initialize dynamic
modules, on python2 this was OK, but on python3 this was raising an
error because `getRequest` returned None:

  File "./parts/erp5/product/ERP5Type/dynamic/component_package.py", line 449, in load_module
    return self.__load_module(fullname)
  File "./parts/erp5/product/ERP5Type/dynamic/component_package.py", line 416, in __load_module
    erp5.component.ref_manager.add_module(module)
  File "./parts/erp5/product/ERP5Type/dynamic/dynamic_module.py", line 86, in add_module
    self.add_request(get_request())
  File "./parts/erp5/product/ERP5Type/dynamic/dynamic_module.py", line 64, in add_request
    self.setdefault(last_sync, (WeakSet(), set()))[0].add(request_obj)
  File "./lib/python3.9/_weakrefset.py", line 89, in add
    self.data.add(ref(item, self._remove))
TypeError: cannot create weak reference to 'NoneType' object

On python2, this was actually raising as well, but this error is hidden
by a `hasattr`, because on python2 `hasattr` ignores all exceptions and
on python3 it only ignores only `AttributeError`.

  File "./parts/erp5/product/ERP5Type/Core/PropertySheet.py", line 61, in createAccessorHolder
    self.applyOnAccessorHolder(accessor_holder, expression_context, portal)
  File "./parts/erp5/product/ERP5Type/Core/PropertySheet.py", line 175, in applyOnAccessorHolder
    for property_definition in self.contentValues():
  File "./parts/erp5/product/ERP5Type/Core/Folder.py", line 1570, in contentValues
    portal_type_id_list = self._getTypesTool().listContentTypes()
  File "./parts/erp5/product/ERP5Type/Tool/TypesTool.py", line 173, in listContentTypes
    provider_value = _getOb(provider, None)
  File "./eggs/Zope-4.8.7-py2.7.egg/OFS/ObjectManager.py", line 323, in _getOb
    if id[:1] != '_' and hasattr(aq_base(self), id):
  File "./parts/erp5/product/ERP5Type/dynamic/lazy_class.py", line 120, in __getattribute__
    self.__class__.loadClass()

And simplify just a bit the code

py3: TestTradeModelLineMixin inherited from UserDict() to store values on the class direcly (!1751).

This does not work with py3:
    File "parts/erp5/Products/ERP5Type/tests/runUnitTest.py", line 941, in main
      result = runUnitTestList(test_list=args,
    File "parts/erp5/Products/ERP5Type/tests/runUnitTest.py", line 703, in runUnitTestList
      result = TestRunner(verbosity=verbosity).run(suite)
    [...]
    File "parts/python3/lib/python3.9/unittest/runner.py", line 184, in run
      test(result)
    [...]
    File "parts/python3/lib/python3.9/unittest/suite.py", line 84, in __call__
      return self.run(*args, **kwds)
    File "parts/python3/lib/python3.9/unittest/suite.py", line 111, in run
      if _isnotsuite(test):
    File "parts/python3/lib/python3.9/unittest/suite.py", line 369, in _isnotsuite
      iter(test)
    File "parts/python3/lib/python3.9/collections/__init__.py", line 1067, in __iter__
      return iter(self.data)
  AttributeError: 'TestComplexTradeModelLineUseCaseSale' object has no attribute 'data'

Use a dedicated dict() to store these values as there was no strong reasons to
inherit from UserDict() here and this makes test implementation easier too...

group_id is used as key of OOBtree and as documented, it's not possible to mix
keys that can not be compared, so we can not have a mix of string and bytes, for
consistency with other BTrees, such as the ones used for OFS.

group_id is also used in a SQL column which is BINARY, this is problematic on
py3 because the selected values will be returned as bytes, but we expect str
here. Because we don't want to run a data migration, we adjust the select
methods to convert to str while selecting.

Since years there was a warning that id_group must be a string, now we make it a
bit stricter, we also enforce that the id_group is valid UTF-8.

A few more tests and assertions were also added.

Since Zope commit 020685087 (`Allow ZPublisher to handle a query string together
with a request body (#1124)`, 2023-05-15) Zope tries to process all XML HTTP
requests as XML-RPC and we need to tell that these SOAP requests are not XML-RPC.

py2/py3: Base64 encode inventory cache, as Shared.DC.ZRDB.DA.SQL tries to decode bytes to str (!1751).
