also str representation of unicode character is different.

User is usually interested by last movement in stock, not by several
months/years old movement. Thus display first fresh movement, and user
could then go to next pages to see oldest movements if needed.

added zope2 compatibility, but nexedi/erp5@21f85a6f (comment 180420) noted
the given assumption isn't true, which is why fixup commit nexedi/erp5@7a2c616e was
added. But nexedi/erp5@21f85a6f (comment 184548) noted
that nexedi/erp5@7a2c616e missed one case,
which is why this fixup commit is added. Now everything should be ok.

Because these two plugins implement the refresh of the authentication
token (unlike the facebook plugin), we can use a longer cache here.
With the previous value of 1 day, when not using the site for more than
1 day, token would expire from cache and user have to authenticate again.
Because the scenario of "access is revoked from authorization server"
is handled by refreshing the access token, we can use a longer duration
here, so that user do not have to login again after not using for two
days.

After server restarts, mariadb uses an error 1927 which is mariadb
specific, with no corresponding constant in CR module when server
restart. This is the case at least with mariadb 10.3.38.

This fix the following problem:
 - start zope and use mariadb connection
 - restart mariadb
 - use mariadb connection again, see an error:
    Error Type: OperationalError
    Error Value: (1927, 'Connection was killed')

This change to treat 1927 as an error for which we can reconnect and
retry the query. Some other connectors do it, for example sqlalchemy in
https://github.com/sqlalchemy/sqlalchemy/issues/5493

This prevents tracebacks during shutdown:

  Unhandled exception in thread started by <bound method Thread.__bootstrap of <Thread(Thread-1, stopped daemon 139820471113472)>>

    File "soft/lib/python2.7/traceback.py", line 100, in extract_tb
      linecache.checkcache(filename)
  TypeError: 'NoneType' object is not callable

Also rename the method because this is not longer *Z*server.

This waitress close() API is not public part of API, so we still ignore
the case where the server thread does not stop after 5 seconds. This
happens if some HTTP connections are still open at the end of test.

   This is expected that constraints can call getConstraintType() if they are filtered:

    return context.checkConsistency(fixit=1, filter={'constraint_type': 'post_upgrade'},)
  Module Products.ERP5Type.Core.Folder, line 1476, in checkConsistency
    error_list.extend(obj.fixConsistency(filter=filter, **kw))
  Module Products.ERP5Type.Base, line 2714, in fixConsistency
    return self.checkConsistency(fixit=True, filter=filter, **kw)
  Module Products.ERP5Type.Core.Folder, line 1476, in checkConsistency
    error_list.extend(obj.fixConsistency(filter=filter, **kw))
  Module Products.ERP5Type.Base, line 2714, in fixConsistency
    return self.checkConsistency(fixit=True, filter=filter, **kw)

    **kw
  Module Products.ERP5Type.Base, line 2686, in checkConsistency
    for constraint_instance in self._filteredConstraintList(filter):

    constraints = [x for x in constraints if x.__of__(self).getConstraintType() in \

   There is a missing "r" on the link, acording to apache documentation:

    Additionally you have to create symbolic links named hash-value.rN. And you should always make sure this directory contains the appropriate symbolic links.

This reverts commit 89aa2a6b.
The assumption that FOR UPDATE was unnecessary is wrong: when SQLDict
reserves similar activities, it will race against these primo-reservations.
So this change actually opens the possibility for duplicate activity
reservation.
Revert this change until (hopefully) a better fix is implemented.
