ERP5Workflow: Remove unused variable_default_value (variable_default_expression should be used instead).

This commit is going to be squashed into:
  ERP5Workflow: DC Workflows are now ERP5 objects (!1378).
  ERP5Workflow: Migrate all DCWorkflows to ERP5 objects (!1378).

Worklist filter objects based on given criterions and thus it makes more sense
for a Worklist to be a Predicate (albeit a Predicate with only Identity Criterion
and nothing else).

Criterion Properties:
  * State Variable.
  * local_roles (SECURITY_PARAMETER_ID): No more ad-hoc check_roles parameter on checkGuard().
  * Any Workflow Variable with for_catalog == 1.
  * Introduce getIdentityCriterionDict()

Also:
  * Remove "ad-hoc" matched* properties: This sounds like a premature optimization.
  * No need for Worklist Variable as these use "normal" Workflow Variables (where for_catalog == 1).

ERP5Workflow: erp5_configurator_*: Migrate Configurator Workflows from workflow_module to portal_workflow (!1378).

This also moves all Configurator Workflows in workflow_module to portal_workflow
(workflow_module was an implementation of Workflows based on ERP5 objects and
not using DCWorkflow code).

* Workflows are now defined on on portal_workflow._chains_by_type anymore but,
  as everything else, on the Portal Type itself.
* portal_workflow can contain and work at the same time with legacy and new
  Workflows (ERP5Type/patches/DCWorkflow.py monkey-patching DCWorkflow classes
  to provide the same API).
* Existing Workflow Scripts should work as they are and the code can be updated
  later on to take advantage of the new API:
  + With legacy implementation Workflow {Scripts,Transitions,Worklists,States}
    were in a Folder ({scripts,transitions,worklists,states} attribute) but
    all of these are now in the Workflow itself and their IDs are prefixed
    (PropertySheet-style), for example `script_`. Legacy attributes are
    provided in new implementation to call the new API.
  + When calling a Workflow Script, `container` was bound to its parent, namely
    WF.scripts (Folder) and a Workflow Script could call another. Now `container`
    is bound to the WF itself and Workflow Scripts are in a Workflow directly.
    New implementation `scripts` attribute handle such use case.
  + Override portal_workflow.__getattr__ so that a Workflow Script can call
    another one without prefix.

erp5_performance_test:testWorkflowPerformance were ran to compare DCWorkflow
and ERP5Workflow implementations and it seems to be about 4% slower with the
new implementation (legacy: 7.547, 7.593, 7.618, 7.59, 7.514 and new: 7.842,
7.723, 7.902, 7.837, 7.875).

Work done by Wenjie Zheng, Isabelle Vallet, Sebastien Robin and myself.

Since nexedi/slapos@0aaa1ccd
cloudooo fonts are now configured correctly.
The snapshots from these tests have been expecting the old, wrong fonts.

This update snapshots to use the new fonts, so that we can
update production cloudooo used for tests.

In e559ecd5 ([erp5_crm] Activate actions for ERP5JS, 2019-09-25) we introduced
a regression, support for erp5_xhtml_style got broken in "Create Response"
when enabling ERP5JS.

It was fixed later in 3125590f (fixup! [erp5_crm] Activate actions for ERP5JS,
2020-10-23).

This extends test coverage for:
 - "Create Response" in erp5_xhtml_style
 - "Create New Event" in both ERP5JS and erp5_xhtml_style

When rendering error page, the default header_title is computed in global_definitions
and this is done by concatenating string:ERP5 (which is unicode) and the
title of the portal (which is an UTF-8 encoded string), which causes an
UnicodeDecodeError, because the portal title was decoded as ASCII.

Because header_title is usually an UTF-8 encoded string, also use an UTF-8
encoded string for 'ERP5' default value.

Following current convention of having x_ui_test for the framework and the
xhtml style tests and x_renderjs_ui_test for the ERP5JS version of the tests.

Revert "erp5_officejs: erp5_hal_json_style Skin is used and without it erp5_officejs cannot be installed."

This reverts commit 1b706b6c. erp5_officejs
depends erp5_web_renderjs_ui which in turn depends on erp5_hal_json_style.

There is no such as thing as "Long Title" in erp5
There is "Title" and "Short Title"

because this business template uses fields from erp5_trade field libraries

These fields were created when proxify action was broken.
This re-exports the fields after using fixConsistency on them.

also add rel="noopener noreferrer" for security.

It seems this workfliow was created by copy-pasting event_workflow,
without cleaning these variables up: they are used by a transition dialog
on event_workflow but nothing on this workflow.
Still, they are stored on every single document on every single transition,
wasting resources. So remove them.

erp5_jquery_sheet_editor: unset Accelerated HTTP Cache Manager configuration in intermediate template.

So different test suites can have a same named sequence without
theme colliding with each other
