Since erp5_xhtml_style has become requiring erp5_jquery. (in reality required since 2010)

This fixes a performance regression introduced in
commit 0a8fbb36
("Simulation: index 'delivery' categories in ZODB")

Built delivery lines are modified by newContent(), before
SimulatedDeliveryBuilder._setDeliveryMovementProperties() has a chance to set
the delivery link on the related simulation movement.
So isGeneratedBySimulation() always returned False.

One solution was to revert all changes in
  product/ERP5/Document/Movement.py
  product/ERP5/Document/SimulatedDeliveryBuilder.py
from the aforementioned commit, but it's much simpler to move the interaction
at the end of the transaction, even if in some rare cases, 2 '_updateSimulation'
activities are created, causing a slight overhead on activity tool.

This approach consists in treating each keys from the default group (the
one for sort on and select dict) as a left join if the key supports it, at
column mapping level.

Also update testERP5Catalog, the specification changed a bit.
Before, using a related key in select_dict had the side effect of not selecting
documents without related documents unless the key is explicitly passed in
select_dict. Now all documents are always returned.

MovementHistoryListBrain links must be pointing to the explanation of the
movement.

92aa42c378783603e90f7ff27208034bdfe5a5e5 reintroduced the random failure. This
restores the same workaround using the 3 item sort syntax

It should prevent a random failure

This way mysql will probably merge this with other constraints on
stock.portal_type when portal_type= is passed.

We were joining catalog for section, node and resource, mainly in order to
expose _title and _relative_url in brains. We just need to select the
corresponding uids and let brains do another catalog search to get the object
when accessed.
Note that erp5_banking_core is not updated
