During indexation we don't apply security checks, so this should be a
little bit faster.

With this change _getProperty becomes a more "official" API, so some
small changes had to be made to classes which do not inherits from
Products.ERP5Type.Base.Base, so that they also implements _getProperty:
 - for ERP5Site we simply use getProperty
 - for the test class from testERP5Catalog, the change is a bit more
important, because this class never defined getProperty, so during that
test we were just acquiring a getProperty from portal.

Optimize edit by calculating the set of restricted accessors only once
at class generation instead of calculating it each call.
Optimize edit by using the same technique to decide if getattr or
guarded_getattr has to be used to get the property.

TempBase had to be special-cased to keep compatibility with some
existing usages of calling TempBase.edit(modification_date=...) where
somewhere in CMF classes a protected setModificationDate exists. Instead
of rewriting existing cases to use something lighter (why do we need
TempBase anyway ?), we do minimal compatibility fix for TempBase only.

Reuse the INFINITE_SET from matrix after moving it to a shared place,
since this is also useful here.

- introduce protected property (ie. with a specific "read permission" / "write permission" ) on Foo
- add a Foo_viewSecurity which displays this protected property

Constraints are supposed to have a getReference and getConstraintType
methods.

for compatibility with Base.checkProperty.

This introduce a `_getProperty` method that's not really part of public
API, but could be called to get a property without security check.
Because some classes were already using internally a _getProperty method
for a different meaning, these methods have been renamed.

This also re-enable parts of test_PropertySheetSecurityOnAccessors that
are supposed to work (security is checked on accessors) and split
what's currently not supposed to work (security on accessors does not
work in the corner case of using the default read permission, 'Access
contents information' as a write permission) to another expected failure
test.

maybe a little to strict. I don't know how we can check that fields does
not display value without checking the markup in a so low level way

[erp5_ui_test_core, erp5_dms_ui_test, erp5_km_ui_test, erp5_configurator_standard_ui_test] setFile command does not need pause command now.

[erp5_web_renderjs_ui] Show select column in view dialog if listbox's select column checkbox is checked.

[erp5_configurator_standard_ui_test] Fix file uploading tests. Use setFile selenium command to avoid security error.

It was possible that the previous server socket did not have enough time
to expire, which could cause an "Address already in use" exception.

url
- corresponding test added

- improve OfficeJS applications by reducing the quantity of code to be written and reuse the ERP5 configuration (portal_type, actions, forms, etc.) instead to generate the app

  The API changed on the slap, this commit follow up the changes.

Which is useful when debugging tests
