This branch is the combination of several optimizations in the ORM:
* store field values once in the cache: the cache reflects more
faithfully the database, only fields that explicitly depend on the
context have an extra indirection in the cache;
* delay recomputations by default: use method `recompute` to explicitly
flush out pending recomputations;
* delay updates in method `write`: updates are stored in a data
structure that can be flushed efficiently to the database with method
`flush` (which also flush out recomputations);
* make method `modified` take advantage of inverse fields to inverse
dependencies;
* filter records by evaluating a domain on records in Python;
* a computed field with `readonly=False` behaves like a normal field
with an onchange method;
* computed fields are computed in superuser mode by default.

A required boolean accepts two values, True and False, however the SSF
and the web-client assume False to be equal to NULL and treat them
interchangeably.
In the SSF, we verify that a required field is filled by checking that
its value is different from False, however False is a valid value for a
boolean, this means that setting a required boolean to False would never
work in the SSF.
This commit overcomes this issue by simply skipping the check for fields
of type boolean.

The SSF would correctly filter out readonly fields when saving a
toplevel form, however it could not remove readonly values when saving
o2m pseudo-records to the parent form (as these would be expected to
remain available for reading upon the next edition and whatnot), so
these values would get sent in 0/1 commands.
Filter out these fields during the parent / toplevel save call.
Complexity notes:
* evaluating readonly modifiers requires the entire record, so
unchanged fields still have to be written back to the parent form
and be filtered out when *it* is set up for save, an alternative
would be to store the `changed` and `readonly` flags alongside the
record dict, and have the post-process only override the
pre-computed readonly flag using force_save
* had to fix a test to match the new behaviour, the post-edition
states turns out to be in line with the client's behaviour (or how
it looks anyway)
Fixes#32019
The extra setup probably affects any o2m whose edition view itself
contains an o2m, but most likely to blow up entirely on models with
some sort of tree structure (parent/child relationship): the SSF
eagerly loads and setups the o2m's view, and the o2m's o2m's, ... ad
infinitam.
A better / cleaner fix would be to set up the subview on-demand (and
possibly cache it), but the rest of the o2m stuff is unlikely to work
correctly recursively so just don't recurse the o2m view setup at all
for now.
fixes#31458
PRs #28645 and #31494 were not applied to 12.0, but there's no reason
not to, they should only fix things (make behaviours more in-line with
the regular client), and since o2m is an area where more fixes are
needed and it would be nice to have them in 12.0...
This widget was exactly the same as a `one2many` and was kept for backward
compatibility reasons. It can be safely removed in master.

The SSF would properly mark its own records as deleted, but it would
not properly handle deletion requests coming from an onchange, and it
would not necessarily convert DELETE_ALL commands (5) into the proper
sequence of individual (2)s matching existing records.

* Form would entirely mis-interpret the server's response to some
results: for unmodified o2m records the server sends a (4), which was
un-interpreted by Form, leading to the o2m record being lost entirely
(as it rebuilds the entire o2m on setting)
* on record creation, every field (except id) is considered modified not
just the fields set by default_get
* Form diverged from actual client in that it would send (1, id, {}) for
unmodified o2m records, actual client sends (4, id, False)
* datetimes should be sent stringified
* onchange should not be triggered when none of the modified fields is
flagged as an onchange trigger
* the default value for numerical fields is 0 not False
* convert m2m onchange results to (6, False, ids) instead of (6, 0, ids)
for ease of diffing with actual client's data
There are still a few odd divergences in the actual invocation of
onchange when attempted on an SO, but they look to be of low relevance
/ risk.
Note: making integer fields "required" has pretty much no effect
anymore. This is in line with (my understanding of) the client's
behaviour, but required the alteration of test models as the
specific test on required... was using an integer field.

The feature was not tested, and as it turns out completely broken:
* the non-raw string means the "backrefs" were really interpreted as
octal literals
* the second backref was entirely wrong
Also add all loaded views to the field descriptor in case we might
have a use for it (and because inline sub-views are always stored on
the descriptor).

Purpose of this commit is to give description more "business oriented"
because those descriptions appears in Odoo Studio which is supposed to be used by end users, not only by developers.
Related Task ID : 37311
In the normal course of saving-action, readonly fields are stripped
out when sending data to the server. The SSF would reuse the same code
when "saving" O2M lines to the parent record however that is not
correct and would lead to misbehaving views as readonly (non-stored)
fields used as "transients" (storing data within the extent of a
record's edition session) would not behave properly.
Fix by overriding the O2M Form's save so that readonly fields are
kept and stored in the parent record.
Closes#23620
Useful to better test business flows & replace yaml test files:
instantiating records & calling onchanges by hand is very
error-prone (it's easy to miss onchanges, or to manually set fields
which can't be set through the view we're interested in, ...)
odoo.tests.common.Form implements the basic *creation*
flow (fields_get, default_get, onchange) up to saving the record,
including proper handling of the required and readonly modifiers &
their domains.
* edition of existing records, including filtering out unmodified
fields when saving
* possibly buttons
* ensuring the API is convenient
