Module action is not a template anymore.

Speed up all calculations.

Do not access the document to modify. Using their UID is enough.
Rely on the listbox which send the list of UIDs when submitting the dialog.

Calculate the list of possible transition by inspecting the portal_workflow configuration.

Do not revalidate the form box twice.

[erp5_core] Use _your validator prefix

This will prevent double concurrent submit.
Mutex can not be used, as it will block the update rendering.

Disable the dialog until the event listener is actived.

Support dialog form box (with your_ fields)

This reverts commit 823842e1

As module may not have the same permissions as its sub-documents

We have a general rule not to really delete content, but for categories and web sections I feel it's different.

( there is [#704](https://nexedi.erp5.net/bug_module/704) but it seems it was a different issue at the time )

All top level documents are not supposed to acquire local roles
https://www.erp5.com/erp5-Guideline.Unset.Acquire.Local.Roles.On.Document.Portal.Type.Configuration.If.Applicable

I believe this comes from the time where we were using images as
sub-documents of products or persons. We now use embedded files for
these cases, so no need to have an exception here.

Depending on the security configuration, there might be a notable side effect of applying this change: images that were visible by some users because they acquired Auditor role from the module will not longer be visible by these users, but they will still be indexed as visible, so they will appear in catalog searches.
In such case, after re-indexing image module the catalog will be consistent again.

Workaround renderjs speed improvement.

In production, the sending of emails by using Internet Message Posts created activity failures :

This Merge Request proposes to allow Entity_sendEmail to be retried in case of ConflictError, as now Entity_sendEmail is doing more than what it used to be.

For this, we need to isolate the call to sendMailHostMessage to make sur that email won't be sent several times if the activity "Entity_sendEmail" is retried.

We also make sure that the activity created to send a message through MailHost gets the correct parameters to be never retried (retry_max=0 and retry_conflict=False)

But only one mail will be sent out by MailHost

Reduce the number of acquired method calls by grouping them.
