Tests have been migrated to the new api to prepare the migration of the
mail module itself. Moreover tests have been cleaned: redundant tests
and unnecessary tests have been removed.
As the base test class in mail is used in other addons, other addons
have been updated :
- portal
- project
- portal_project
- website_project_issue
- sale
- purchase
Future commits will come with somes fixes for issues detected when cleaning
the tests.
When auto subscribing to a message
(For instance, change the ```user_id``` field on a record,
like an invoice)
The new user is notified of the last message of the thread.
He must be notified of the parent message as well,
to have access to the first message of the thread,
to prevent access rights issues to the thread.
This mechanism is applied in the _notify method
of model ```mail.message``` as well, for the same reasons.

The timezone of hr_analytic_sheet should be the timezone
of the employee as well, so sheet analytic lines and attendances
lines are grouped within the same timezone, the timezone
of the employees, so the time difference between the analytic
lines and the attendances lines can be properly computed.

Reduce memory footprint of server
The tricks used are:
- use a global LRU for `ormcache` (auto-balancing between registries);
- remove unnecessary data structures (binary class hierarchy of models);
- compute some data structures on demand (`_all_columns`);
- optimize field attributes (empty collections may be shared);
- optimize memory size of fields and columns by using slots.
On a database with modules sale, purchase and stock installed, the memory footprint of the registry went from 20.3Mb to 7.4Mb (as measured with heapy). In other words, the memory footprint was reduced to 1/3 !
In ormcache, those statistic numbers were counted per cached method for all
registries. We introduce separate statistic counters, and create a counter per
(database, model, method). The existing attributes that are no longer used
have been removed.
The registry size is now assumed to be around 10Mb, and ormcache size is
proportional to the maximum number of registries. Statistics about ormcache
usage is shown to the log when receiving signal SIGUSR1.
In `__getattr__`, remove the test on accessing `_attrs`. This situation should
never happen, since the attribute `_attrs` is set in method `__init__()`.
Introduce slots on all field classes for common attributes; slots take much
less memory than a `__dict__`. The other attributes are stored in a dictionary
`_attrs`; all fields with an empty value for `_attrs` (common case) share the
same empty dictionary. This saves quite some memory (around 4.5Mb per
registry), given the number of field instances created for a registry.
Another mechanism is used for the default values of attributes, since slots
cannot be assigned on classes.
The optimization consists in using tuples for attributes `inverse_fields`,
`computed_fields` and `_triggers`, and to let them share their value when it is
empty, which is common. This saves around 1.8Mb per registry.
This saves about 400Kb per registry by not allocating those lists, which are in
most cases empty. The removal of the attribute will also simplify a bit the
management of free attributes.
The computed value of parameter digits is no longer stored into fields and
columns; instead the value is recomputed everytime it is needed. Note that
performance is not an issue, since the method `get_precision` of model
'decimal.precision' is cached by the orm. This simplifies the management of
digits on fields and saves about 300Kb per registry.
Sometimes, the expected mro of the model is not the same as the one built with
a binary class hierarchy. So we reorder the base classes in order to match the
equivalent binary class hierarchy. This also fixes the cases where duplicates
appear in base classes.
Instead of composing classes in a binary tree hierarchy, we make one class that
inherits from all its base classes. This avoids keeping intermediate data
structures for columns, inherits, constraints, etc. This saves about 600Kb per
registry.
The mappings model._all_columns takes quite some memory (around 2MB per
registry) because of the numerous dictionaries (one per model) and inefficient
memory storage of column_info. Since it is deprecated and almost no longer
used, it can be computed on demand.
The ormcache is now shared among registries. The cached methods use keys like
(DBNAME, MODELNAME, METHOD, args...). This allows registries with high load to
use more cache than other registries.
QWeb templates can be translated, javascript code
included. Nothing prevents you to translate
the javascript reserved word "undefined", for instance.
Preventing the livechat JS snippet to be translated
prevent translations mistakes, like translate
```undefined``` by ```Niet gedefinieerd```

The BBA communication is now only checked when provided as input
(created or modified).
Avoids useless check for uniqueness when it's not modified, and
prevent errors when several invoices are modified in batch.
