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.

Purpose
=======
Fields `customer` and `supplier` on `res.partner`
are mostly used in domains of many2x fields.
Those domains can confuse end users because they don't
see the partner they are looking for; and it's not obvious why.
Some identified problems:
1. It can lead to duplicated partners: the user does not find
the partner, so he creates a new one.
2. The user imports supplier contacts in the Contacts app, so they
don't get the `supplier` flag. Then the user wants to make a purchase order,
and cannot find the new suppliers in the list
3. A user removes the customer flag on a prospect, because they don't think
it's a customer yet - except now they can't make a quote for that customer...
Specification
=============
Remove the two mentioned fields.
Since fields `customer` and `supplier` have been removed, all partners
are now shown in many2one dropdowns.
But in some cases, not all partners are relevant or some are more likely
to be relevant than others. e.g. when creating a PO, top suppliers have a
higher priority than other partners.
So, adapt the places where those fields were used with the new mechanism to
display the searched the partners, according to the number purchase/sales
orders they made.

The method `read()` may be very slow when reading relational fields and
computed fields, because the computed fields can be computed on a recordset
that is larger than expected.
The issue occurs on model 'res.partner' when reading fields 'child_ids' and
'purchase_order_count', for instance. Suppose we read those two fields on a
partner with 1000 contacts. First, the one2many field is read from the
database and stored to the cache; the latter adds the value ids to the
prefetching of 'res.partner'. Then, the fields are fetched from the cache.
When 'purchase_order_count' is accessed on the partner, the field is computed
on all its children as well...

This commit replaces calls to pycompat helpers that were intended for
python 2 <-> python 3 interoperability for python 3 builtins, as python
2 is no longer officially supported by Odoo.
This includes:
* calls to imap/izip/ifilter replaced by map/zip/filter
* uses of text_type replaced by str
* uses of unichr replaced by chr
* calls to implements_to_string, implements_iterator removed
* string_types and integer_types replaced by str, int respectively
* calls to to_native replaced by calls to to_text
This is done in preparation to the removal of these deprecated helpers
in the following commit.
- Update all the pictures
- Rename the partners with a name that is easy to say for an English speaker (No more 'Agwoleight')
- Update all the addresses/phone numbers in the american format
- Unify the demo data with the new theme (Wood shop/manufacture,...)
Now that we're closer to switching to P3 for good, these helpers have
outlived their usefulness, and mostly add noise.
All remaining dict.iter*() or dict.view*() must be converted to the
normal keys(), values() or items() calls.
Whenever the result is likely to be used for more than the scope of a
loop, or when the dict needs to be modified during iteration, the calls
must be wrapped in a ``list()``, to protect the new P3 semantics.
Those cases are very exceptional.
Also removed some dead code or improved the API to remove unnecessary
conversions.
In Python 3:
* various builtins and dict methods were changed to return
view/iterable objects rather than lists
* and the separate Python 2 view/iterable builtins and methods were
removed altogether
This is problematic when using these items as list (which the happens
repeatedly in Odoo), but more viciously when iterating *multiple times*
over them (which also happens, which I've messed up multiple times while
writing this, and which is a pain to debug even when you've just created
the issue).
Convert all code using these to semantics-matching cross-version
helper functions to get the LCD behaviour between P2 and P3, and
forbid the builtins via lint.
