This uses `from __future__ import print_function` from "unrestricted" python code.

For restricted python in python scripts, this expects SlapOS to have nexedi/slapos!1536 .
Running ERP5 with this patch on an old SlapOS software release should probably be OK,
especially because after all we don't have so much critical code using print.

To ease migration of custom project code, PythonCodeUtils was modified so that
when running CodingStyle python scripts are checked with print_function future enabled.

  Since the test() method was fixed the comment became irrelevant

Returning true allows to add movements to existing one, and this group shall
always separate them.

I investigated a case where activities calling an external API were not
retried after the initial failure, when it was caused by
TimeoutReachedError:

https://lab.nexedi.com/nexedi/erp5/-/blob/f41b33cd91348a800db3b95b30efd857f583bcde/bt5/erp5_web_service/MixinTemplateItem/portal_components/mixin.erp5.RESTAPIClientConnectorMixin.py#L142

The interesting thing is that these activities are written in a way that
allow them to be retried (automatically, or manually) without causing
un-intended side effects, like creating twice a document in the external
API. So not having SQLBase retrying them automatically is a pity.

The bug is that the use of TimeoutReachedError here was intended only
for the activities that are aborted by CMFActivity itself, and not for
the userland code that can also use TimeoutReachedError.

This commit removes this special processing, as there is no need to
especially not retry the activities that trigger the CMFActivity
timeout. The max_retry decision should be taken by the calling code, and
not by CMFActivity.

This flags python2 style usage of print as a statement

(not yet for scripts under portal_skins)

adjusted (by Jérome) to just remove call to print in a few places where
it made more sense.

 Move Simulation to priority 3 helps to not block/delay immediateReindex
 on a scenario where everything is expanding. We use priority 3 to match
 what is used in SimulableMixin.updateSimulation and Delivery.localBuild

This fixes compatibility for python3, especially with hash randomization
(PYTHONHASHSEED) turned on.

This also enables coding style test that was not running for this bt,
after fixing everything flagged by coding style test.

Make sure we see *all* warnings, both in the tests and in the logfile in production.

Fix many warnings by updating imports and calls to deprecated APIs

for consistency and because it's probably good to let user choose
sending mode.

This matches the form title

When producing DSN report, there was a few places where we depended on
dict iteration order, so the test did not pass when running with
PYTHONHASHSEED (erp5_payroll_l10n_fr:testDSNSocialDeclarationReport
fails with PYTHONHASHSEED 323). In these changes we add sorts to some
places where we were iterating on dicts so that the order of the Lines
is deterministic even with hash randomization enabled.

test was simplified not to use difflib, unittest does a good job of
explaining the differences when using splitlines on long texts, no need
to compute a diff ourselves.

   Without this the redirection places value unquoted causing parser to fail
   later on when resolve {n.me}.

   came_from cannot be None so we simplify the block a bit.
