Web sections or web sites displaying a default page should have
modification date after the modification date of their default page, so
that the "if-modified-since" requests can be replied with a 304 not
modified responses.

Upgrader detects that if some type have constraints and their container
type also have constraint, it's not needed to check again this type
because since checkConsistency is recursive when the container is
checked they will also be checked.
This fails when we have situtations like:

  X is allowed in Y
  X is allowed in Z

and there are constraints for by X, Y and Z.
This was raising a KeyError when pop'ing Z :

    Module script, line 50, in Base_getConstraintTypeListPerPortalType
     - <PythonScript at /erp5/Base_getConstraintTypeListPerPortalType used for /erp5/portal_alarms/upgrader_check_pre_upgrade>
     - Line 50
      type_list = constraint_type_per_type.pop(allowed_content_type)
    Module AccessControl.ZopeGuards, line 104, in guarded_pop
      v = guarded_getitem(d, key)
    Module AccessControl.ZopeGuards, line 83, in guarded_getitem
      v = object[index]
  KeyError: 'Z'

In fact, this code is wrong, because if Z is also allowed in W and W
does not have constraint, then Zs inside Ws will not be migrated. In
practice, that's probably OK for now, because we don't use migration
constraints on documents so much, most of the time we only do one
script that checks the constraint globally.

Folder_getDeleteObjectList could do an extra paranaoïa check that the
caller did not pass an empty list of uids, because this would cause the
script to iterate on the full catalog table.

We now have getRelationCountForDeletion API for this.

The general approach is:
- replace deprecated lambdas with list comprehensions
- remove unused variables/imports
- replace dangerous arguments [] with ()
- replace dangerous arguments {} with None and "if None -> {}"
- replace builtin names with something similar

Now that all problems reported by pylint are fixed, enable coding style
test.

This was not valid HTML5:

  AssertionError: Using nu validator to parse the view "SQLMethod_view" (from erp5_core bt) with warnings displayed :

This fix a regression from 920655a2 : when item has no tracking, uid was
passed an empty list and this fetched all catalog.
Also call getObject explicitly only once instead of having it called
implicitly twice.

erp5_project does not depend on erp5_budget, so instanciating project
cell fail unless erp5_budget is installed.

Project Cell are not used by default, so it's still a bit unclear, but
with erp5_budget we can directly define budgets by project / project
lines in a more flexible (but also more complex).

Project Line uses OrderLine, so it's consistent to use OrderCell for Project Cell.
