tables() method of ZMySQLDA returns also views, which are not deleted
with DROP TABLE but with DROP VIEW instruction.

After discussing on
nexedi/erp5!1103 (comment 104474) we
amended the original commit so that if there are no bt to install at
this point we consider this step is finished (use 1 and not 0)

It may not be the case if there is only one view, as defined by the hateoas spec

for Base_getDocumentScannerDefaultBackendDataAsJSON
since we need to be able to create Active Process

Add them to BaseAccessorHolder (like `Base Category` accessors) instead of
Base class so they can be regenerated on reset while not having to remove
ZODB Components from Base class on reset.

This means that providesIFoo() will only be available on Portal Type classes
whereas before it was working for direct Document instanciation, but the latter
has been banned for several years anyway and the few remaining ones have been
fixed (23b2b5fd, e791d08a).

Also, instead of Base.provides() being a CachingMethod() (does not work with
resets), create a method dynamically on the Portal Type class (erp5.portal_type.Foo),
as not caching at all is ~18 times slower.

And thus filesystem Interfaces were not displayed/selectable in BaseType_view.

erp5_certificate_authority: Certificate Authority Tool: All ERP5 objects *must* have have a Portal Type in Types Tool.

And remove hack in erp5_promise which was creating a non-Portal Type class of
portal_certificate_authority. Instead, add a depend on erp5_certificate_authority.
`providesI*` accessors are now in BaseAccessorHolder rather than Base due to ZODB
Components, this breaks reindexing (`AttributeError: providesIPredicate`).

This gets rid of:
  WARNING ERP5Type.dynamic Cannot find a portal type definition for 'Certificate Authority Tool', trying to guess...

This has been banned since the introduction of Portal Type class. When creating
a new ERP5Form via addERP5Form/ZMI, its MRO:
  * Before:
    <class 'Products.ERP5Form.Form.ERP5Form'>
    <class 'Products.ERP5Type.Base.Base'>
    ...
    <type 'ExtensionClass.Base'>
  * Now:
    <class 'erp5.portal_type.ERP5 Form'>,
    <class 'Products.ERP5Form.Form.ERP5Form'>,
    <class 'Products.ERP5Type.Base.Base'>,
    ...
    <class 'erp5.accessor_holder.property_sheet.SimpleItem'>
    <class 'erp5.accessor_holder.property_sheet.Folder'>
    <class 'erp5.accessor_holder.property_sheet.Base'>
    <class 'erp5.accessor_holder.property_sheet.CategoryCore'>
    <class 'erp5.accessor_holder.BaseAccessorHolder'>
    <class 'Products.ERP5Type.dynamic.portal_type_class.GetAcquireLocalRolesMixIn'>
    <type 'ExtensionClass.Base'>

Thus it was missing many accessors and was working only by chance (or at least
unless these accessors were not called until the object was automatically migrated
by the next call to __setstate__). Namely, as `providesI*` accessors are now in
BaseAccessorHolder rather than Base due to ZODB Components, this breaks reindexing
(`AttributeError: providesIPredicate`).

Also, remove hardcoded _getAcquireLocalRoles() now that it is not used as a regular
class anymore. Set this on the portal type object instead.

This gets rid of:
  WARNING ERP5Type.dynamic Cannot find a portal type definition for 'ERP5 Form', trying to guess...

Expanding frozen Simulation resulting from a split and Defer raise a `NotImplementedError`.

It comes from the `_extendMovementCollectionDiff` function in [RuleMixin](product/ERP5/mixin/rule.py) checking the recorded property "Quantity". The Quantity Split Solver set this variable to zero hence leading the function to consider compensation is needed. This merge request remove the setting of the recorded property `quantity` on the the split movement. Re-expanding from the root was also removing that recorded property asking the question if this is needed.

As of now system having used Split and defer Quantity will most likely not be able to re-expand their resulting simulation.

A Test is added to validate the fix.

Caching forever would produce wrong results after installing a business
template containing interfaces, using a transaction cache is enough
(actually it may not even be needed).

We were not considering interface without the I prefix for component
interfaces

Like we do in product/ERP5/tests/testXHTML, this form does not work
without preferences

Not that the old `reversed` function was different from the builtin, we
replace it with sorted(reverse=True) to keep the same logic.

This is a dependency of erp5_credential, it should be installed in the
test.

This fixes a test failure,
portal_notification.sendNotification(store_as_event=True) is now an
error when erp5_crm is not installed.

Add some features to restricted python and fix problems revealed by running Zope's test suites.

# Bug fixes

 - Disallow access to old style classes without security declarations. This is not allowed in vanilla zope, but we allowed this accidentally about two years ago. This branch includes some fixes for cases where we accessed not protected classes in a way that should not have been allowed - ERP5 test suite pass, but there might be more cases in code not covered by ERP5 test suite.
 - Fix iterating on `reversed(iterable)` which was unauthorized, maybe since python 2.7
 - Disallow new style classes in container access (iteration, `{}.get` etc). Only classes had this problem, not instances, so this probably has no impact for us, but it allows running AccessControl test suite.
 - Disallow attribute names ending in `__roles__` in class name. This probably does not impact us either, but also for AccessControl tests suite.


# New features

 - Allow iterating on a generator. It's still not possible to use `yield` statement in restricted python, but iterating is now possible
 - Allow `cStringIO.StringIO("initial value")`, only `cStringIO.StringIO()` was allowed
 - Enable `collections.namedtuple` and add a few tests for other members of `collections` ( not `collections.deque` because we never used it so far )

This uses the new "only ERP5JS" actions to enable components editor in ERP5JS, so that we can edit components on ERP5JS .

This does not change anything in the old UI (erp5_xhml_style), where the editor field will still be used.

This test loads a reference Data.fs, but we don't want to connect to
the mysql referenced in the mariadb, because it might be used by another
test node.

Before the beginning of the test, rewrite the connection string to the
one this test node is using.

This relies on an updated dump produced in nexedi/erp5-bin@8310e4e4

Allow to set more categories (funding and function)

Allow to configure a script to "unset" categories, to address this issue that sometimes we do not want to keep categories from input movements.

`erp5_authentication_policy` can be configured to automatically create `Credential Recovery` for user once login expire.

This was no longer working since we switched to `ERP5 Login`, `Credential Recovery` ticket was created with a relation to `ERP5 Login`, but it should be related to the `Person`.

* Check that frozen Simulation from a Split and Defer can be expanded

testPackingList: test_11_01 Check Expand is stable

This is the loyalty programme for commerce.

Idea is to use modelled trade model lines, at least three lines are needed:

  + One trade model line to define how to collect loyalty point

  + One trade model line to define how to use loyalty point
  + One trade model line for discount
  + .....

New loyalty transaction is added to record loyalty point.
