The _auto_init method was overriden without keeping the return value of
the super on some models.
This break the new stored computed fields computation at field creation.
Closes#11985
opw-677232
When importing a CSV file with an "id" column containing
external IDs (XML IDs), the system automatically creates
or updates the corresponding ir.model.data entries.
This would fail for regular users who do not have
create/write access on this internal model.
When a new ir.model.field is created, add the new field in the fields_by_model (cache of custom fields). This is required as the __init__ method would not retrieve the new field if fields_by_model is already set.
Otherwise, the _columns would not contain the new fields and we could not access it without restarting the server (e.g. the installation of a module adds ir.model.fields and use it in the a view.
Comparing an id and a browse record will always fail so the exception would have always been raised when changing a model (e.g. updating a module with custom fields).
orm: do not try to create ir.model.relation for custom m2m as self._module is either empty (for custom models), either the one of the last inheriting module (which is wrong). The field should be removed manually and should not be impacted by the uninstallation of modules. The removal of the relation table can be done when removing manually the custom field (see rev 6af3193).
ir.model: when removing a model, drop the table with the CASCADE instruction. This will remove left constraints from remaining m2m tables.
This means that dropping a table (either manually removing a custom model or uninstalling a module) will not drop the relation table for a custom m2m field. This is not ideal but better than the previous behaviour (which was to fail the DROP TABLE instruction and keep the table with a few columns and unconsistent data).
When droping a column, remove also the relation table in case of custom m2m field.
The relation table needs to be dropped otherwise an unremovable constraint to the targetted table is kept (and anyway is not needed anymore).
When uninstalling a module, remove the ir.model.constraint after removing the non-model records and before fields and model definition.
Without this fix, some constraint would be removed too early allowing to have broken relations and data left from removed module.
The _auto_init call in ir.model.fields creation will not
do it because it happens before the insertion of the model
in the registry. It will only work for later addition of
fields.

Some important points to consider:
- signaling should be done after any schema alteration (including module [un]installation),
service registration (e.g. reports)
- the changes need to be committed to the database *before* signaling, otherwise an
obvious race condition occurs during reload by other workers
- any call to restart_pool() must be considered a possible candidate for
signaling, and the 2 above conditions must be checked
The number of explicit calls was reduced by forcing the signaling at the end of
Registry.new() in case `update_module` was passed as True. In that situation
we always want to signal the changes - so all the redundant signaling calls
can be centralized. We can also assume that the relevant changes have already
been committed at that point, otherwise the registry update would not
have worked in the first place.
This means that there is no need for explicit signaling anymore everytime
`restart_pool` is called with `update_module=True`.
Some missing cr.commit() and explicit signaling calls were added or
moved to the right place. As a reminder: signaling must be done
*after* committing the changes, and usually *after* reloading the
registry on the current worker.

Otherwise a previous validation (or 2) will poison the cache and the
import itself will fail even though the validation succeeeded (and
importing with no validation would have succeeded), as the orm cache
doesn't take DB rollbacks in account.
