Since the change for use of User ID this code should return reference and portal type of the ERP5 Login object.

  The implementation of external_login expects the reference of an Login object and the portal type of itself

Include draft of facebook Oauth code.

  This method and call is duplicated on several places

  The user can be present from diferent logins, password tool only works with ERP5LoginUserMager
  users.

Returning true allows to add movements to existing one, and this group shall
always separate them.

uid is used internally during recursive calls and using uid can lead to
traverse all lines of catalog.

Note: Generic code shall have no constraints at all.

It will protect against storing truncated data.

If 2 lines have the same effective date (catalog has a 1 second precision),
always return the validate and open first.

From Lukasz Nowak:

1- Compensation is undesired. (51c8a250)

  Raise loudly with message.

2- Disallow any compensation. (3c74ed07)

3- Emit more informative log. (534b2e77)

Also minimise activity hurricane by calling expand directly.

Open Orders are searched using indexation timestamp, which allows to see them
in "windows", and does not repeat expand if not needed.

Generate activities and allow to pass the tag. Use search and activate
everywhere which will allow to walk through objects without killing the cluster
even in case of really big documents.

Avoid calling isDivergent which can take few minutes to finish.

causality_state comes from well designed causality workflow, which informs
enough about delivery state. Fetching causality_state property is extremely
fast.

Notes:

Do nothing on 'calculate' instead of disabling *_causality_interaction_workflow as
these interaction workflows do not generate activities directly, and do work
that can't be postponed.

By contrast, 'calculate' transition of delivery_causality_workflow is modified
so that no 'updateCausalityState' activity is created by default.

This commit also update list of method_id which should not call calculate_causality

This merge request is trying to provide an API so that we can construct urls in a more organised manner than manipulating strings.

The motivation, started from this merge request: nexedi/erp5!333, where absolute_url is overriden for Web Section and Web Site. Then we found that we have to do many dirty changes like:
```
              absolute_url python: here.absolute_url();
              absolute_url python: absolute_url[:-1] if absolute_url.endswith('/') else absolute_url;
```
(more of those in nexedi/erp5@f601d7a5).

So we said we should make an API to have an organised manner, like we have e.g. Base_redirect to handle redirects.

- First commit adds this as a script in erp5_core, along with a test.
- Second commit uses it. It is not on my scope to change all erp5 code, but I focused on changing on the things I already had to in
nexedi/erp5@f601d7a5

@romain , @kazuhiko please make comments. Tests passed, but not on the final revision (did some amendments) and I think better not to re-run suite  before getting comments. Also, @tatuya , I think you are responsible for ERP5 interfaces, so I would like your opinion if erp5_core is the good place, or maybe some other BT or product.

My plan would be to merge this and then nexedi/erp5!333 rebased on this. But in any-way this should be separate from nexedi/erp5!333.

fix attachment parallel synchronization issue

inotifyx is has no support for Python 3 and
it does not seem to be maintained anymore.

The erp5 site creation fails due to a dependency error. Dependency to erp5_full_text_myisam_catalog was added to the erp5_scalability_test business template.
