This partially reverts commits 5d746d0ac6 and
73de86c768.
The tightening of access rights was too strong: regular users need to be able
to read models and fields (to create an email templace, for instance.)
[FIX] ir_values: in `get_actions`, exclude field `code`
The computed field `domain` was formerly read as the current user to evaluate
the rule's domain for the current user. As we restrict the access of `ir.rule`
to advanced users only, the computed field has no purpose anymore.
Remove unrestricted "read" access. To make code internally using `ir.model`
work, add a private method `_get` on `ir.model` to retrieve the record
corresponding to a model name, without access rights issue.
Change signature of method `get_authorized_fields` to make it use a model name
instead of a model id. This removes the necessity of a search on `ir.model`.
ir.needaction_mixin is not used anymore by the webclient.
From 9.0, the concept has changed: this feature is now
available in mail module, with the mail.thread mixin,
and message_neeadction field.
Remove all code handeling needaction bullet and
counter on ir.ui.menu, knowing that since 9.0
webclient does not display the counter anymore.
This code was, thus, useless and some RPC calls
were done for nothing, and adapt accounting
reconcialiation widget.
