To workaround a bug with our old pylint / astroid versions

Revert "py3: sortKey() must be a string as comparison between str and None/int/tuple now raises TypeError."

This reverts commit 192c2000.

This commit introduced a test failure with testCommitOrder
testInvalidationBug.TestInvalidationBug [1]

    Traceback (most recent call last):
      File "Products/ERP5/tests/testInvalidationBug.py", line 93, in testCommitOrder
        self.assertEqual(result_list[1], [0,0])  # activity buffer first
    AssertionError: Lists differ: [1, 0] != [0, 0]

    First differing element 0:
    1
    0

    - [1, 0]
    ?  ^

    + [0, 0]
    ?  ^

That commit was apparently in the good direction, because transaction
API specifies that sortKey must return string

using a css selector also matches:

    <div class="transition_message transition_message_success">Deleted.</div>

unlike the xpath selector which matches only element where class
attribute is exactly "transition_message"

Define min and max to integer html field

when defining start and end property in ERP5 integer field

"template_keep_path_list" definition was wrong, the tool is uninstalled
when updating in wrong order

This allows executing a script doing REQUEST.RESPONSE.redirect() without
error.

Before this patch it's an AttributeError similar to:

    ------

    Traceback (most recent call last):

    AttributeError: TimerResponse instance has no attribute 'redirect'

Instead of temporarily changing the global timeout, which can impact
other parts of the system and which is not free from race conditions (
another thread might have changed the timeout when socket.getdefaulttimeout()
is called and then we restore a wrong default timeout).

   For facebook and openid buttons.

  Like in WebSite_login, came_from is an URI Template so we must expand the URI to handle the {&n.me}
  that can be present on the URL.

With Python2, properties were all str(). with Python3, we need to distinguish
binary-like properties from text-like properties.

This should ideally be implemented by checking PropertySheet elementary_type
(such as `data` for bytes() and `string` or `text` for str()) for each property.
For now (bootstrap/addERP5Site) though, let's consider all properties in .xml to
be UTF-8 str() and statically define which is which for non-.xml files.

And _mysql/mysqldb API (_mysql.connection.query()) converts the query string to
bytes() (additionally, cursor.execute(QUERY, ARGS) calls query() after
converting everything to bytes() too).

Done through various 2to3 fixers (zope.fixers, modernize, future) and manual
changes. This is a single commit so that we have a clearer picture of how code
converted with my2to3 should look like.

Except straightforward @implementer decorator 2to3 fixer, only product/ folder
was considered as the goal was to be able to create an ERP5Site.

* Use @implementer decorator introduced in zope.interface 3.6.0 (2010):

  The implements syntax used under Python 2.X does not work under 3.X, since it
  depends on how metaclasses are implemented and this has changed. Instead it
  now supports a decorator syntax (also under Python 2.X).

  Applied thanks to 2to3 `zope.fixers` package.

* Use `six.moves` rather than `future` install_aliases() feature because the
  latter use unicode_literals and "wraps" module aliases so that unicode() are
  returned for text rather than str() (Python2 standard library). This notably
  breaks BusinessTemplate code which uses urllib quote() for filesystem paths...

* No more unbound methods in python3 so use six.get_unbound_function().

* dict.(iteritems,iterkeys,itervalues)() => six.\1(dict) thanks to `dict_six`
  2to3 fixer from `modernize`:
  $ python-modernize -w -f dict_six product/

* Manually make sure that dict.{items,values,keys}() returns a real list when it
  is latter modified rather than a dict_{items,values,keys} (ensure_list()). By
  default, 2to3 blindly does list(dict.{items,values,keys}()) which is not
  acceptable from performances point of view. With my2to3, this will be possible
  to handle such case automatically.

* Replace cStringIO.StringIO() by six.moves.cStringIO() (a module alias for
  cStringIO.StringIO() on py2 and io.StringIO() on py3).

* Use six.text_type which maps to unicode() on py2 and str() on py3. This also
  makes a clearer difference between text and binary strings.

* Replace map()/filter() with lambda function by list comprehension (this has
  the benefit to avoid casting to list for py3 as it returns iterators).

* past.builtins:
  portal_skins/erp5_core/Base_sortObjectListLikeSQL:0:2:Redefining built-in 'cmp' (redefined-builtin)
* six and six.moves imports:
  + portal_skins/erp5_core/Base_updateListboxSelection:0:2:Redefining built-in 'basestring' (redefined-builtin)
  + portal_skins/erp5_core/ERP5Site_checkDataWithScript:20:2:Redefining built-in 'xrange' (redefined-builtin),

Use the latter form that works on both. On non-PythonScript code, this is of
course not an issue but Python2 PythonScript does not have a __code__ properties
and requires a patch on Shared.DC.Scripts.Signature (applied by SlapOS recipe)
so that FuncCode() object is set to not only func_code but also __code__.

And also disable pylint patch as pylint version with Python3 support is not
supported yet by ERP5...

* Add functions to properly convert/handle bytes/str/unicode (from
  slapos.util) (stricter than six.ensure_{text,str}()).
* Python3 {keys,values,items}() now returns dict_{keys,values,items} rather than
  real list() so add ensure_list() to create a list() when it is latter modified
  but do nothing on Python2 for performance sake.

  File "product/TimerService/timerserver/TimerServer.py", line 71, in run
    s.send('GET / HTTP/1.1\r\n\r\n')
TypeError: a bytes-like object is required, not 'str'

And Zope4 now mandates it to be a string ({Shared.DC.ZRDB.TM.TM,ITransactionManager}.sortKey()).

This changes the API to implement similar feature in Python3, but this should
not be an issue because Interactor are only for non-ERP5 object...

py3: AccessControl users_with_local_roles() returns a dict_keys() instead of a subscriptable object.
