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. Work done by Toufik Ben Jaa, Raphael Collet, Denis Ledoux and Fabien Pinckaers. closes odoo/odoo#35659 Signed-off-by: Denis Ledoux <beledouxdenis@users.noreply.github.com>
