In case of foreign language, using unicode characters, the error message may be
badly formated.
e.g.
Unknown error during import: <class 'odoo.exceptions.AccessError'>: เฉพาะผู้ดูแลร..

When deciding to prefetch records (getting records from the cache with
no value for the field being fetched), if the field was computed
`determine_value` would just get all records, not limited by the normal
prefetch limit; for large recordsets this would generate gigantic
prefetch lists for records we may not need at all.
Fix by applying the `PREFETCH_MAX` limit to records from the cache as is
done in `_prefetch_field`.
Complementarily, when traversing related fields the prefetch
environment would be lost and every record would get an empty prefetch
environment, so the values would ultimately be read one by one.
Example: select (search) 1000 product.product records, access a
related field (e.g. categ_id) in a loop, on the first iteration the
system would first read 1000 templates, then it would read each
categ_id individually, resulting in >1000 SQL queries rather than the
~2 we would expect.

When a model contains a field translatable which has a unique
constrain, it is impossible to copy a record. Indeed, the unicity
constrain is always triggered, even if the model takes in charge the
overriding of the copy method to avoid duplication.
Introduced with commit ce7f31b0b0, with the goal to target only
XML/HTML translations. We apply this behavior in case of a callable
translate property, to target only the desired problematic use case.

Issue: when using `copy` in a given lang, the value of XML/HTML fields is
copied in its translated form, making existing translations useless. Fix the
value of such fields by storing their original value instead.
This fixes the following issue. Assume a custom field F is created on
`res.partner`. This field will appear on `res.users` as an inherited field,
and will be reflected in `ir.model.fields` as a 'base' field. When F is
removed from the parent model, it no longer appears on the child model in
registry, but remains in `ir.model.fields`.
The patch allows the proper removal of the no-longer-inherited field from
`ir.model.fields`.
Different method use self._context.get('lang', 'en_US') to get the lang
value but, the lang in the context can be set to None (eg: copy method).
When the context is used with a lang=None, the method can have a
unexpected behavior or crashed (eg: if you try to format a datetime with a
locale=None)
When copying a record in an other language L than US, first a translation
was created for L by the create called in the copy function and afterwards,
a second translation was created by the function copy_translations
So there were two duplicated translations for L instead of one.

The call of the name_get on records with falsy ids was unnecessary
as it wasn't used afterwards and could lead to errors if a name_get
doesn't handle falsy records.

The fields objects are responsible for creating their column/table and indexes.
The methods that update the schema are overridden to handle cases specific to
each type of field.
