[IMP] models: ORM speedup

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.
