Since revs 53582c2ea6 & f65c913027,
this was no more possible for portal users to read groups
on purpose, for privacy reasons.
fields_get of res.users model is overriden, for
the access rights form view features
(The groups selections and checkboxes).
At each call to fields_get, which happens at each call
to fields_view_get on the res.users model, operations are
done on the model res.groups (basically, to
build the selection groups and checkboxes). So,
each time a view of model res.users is displayed,
whatever the view, operations on res.group model were performed.
The thing is, these operations on res.groups
are actually needed only for the user access rights
view, or at least only for users having the group
Administration > Access rights. These group operations
aren't needed for the preferences view, nor for portal users.
We therefore avoid to do these if the user is not part of the
Administration > Access rights group, which lead to
performances improvment, and solves the fact
portal users couldn't access their user preferences view.

After commit 0ed63d73a6,
the hack used to detect fields.function is not supported
anymore. Using `isinstance` is safer and cleaner anyway
(performance is not a concern here).
When switching an applicant to another stage,
there is the possibility to send an email template,
according to the given stage.
The attachments defined in the email templates should
be sent as well.

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.

(created or modified).
Avoids useless check for uniqueness when it's not modified, and

The same holds for the inverse history_ids relationship. When an object is copied,
the many2many fields their links are copied.
When we copy a done move as is done in the return wizard to create the reverse, it copied also
the relationship with the quants. This is problematic as this field indicates the quants that
were transferred by the move and the new move will think it will have returned all the quants
even before it is done.
In the accounting settings, we prevent having gain and loss accounts that are linked to a
different company than the one selected for the chart of account.

Currently, the view_form search_count doesn't propagate the context, so when
searching on a translated field, the count can be different than the one we
would expect and get with a search in a current language different than en_US.

`product_qty` field is not recomputed at record creation.
Force field recomputation at any change
Removing the trigger on `product.product` should not be a problem as
product uom can't be changed once there are move lines.

The sequence for new items in some models is simply set to a constant 10.
Hence if 3 items had after reordering sequences 10, 11 and 12. If a new item is
added, it would get after saving at the second position.
This fix set the sequence of a new item to the maximum+1 or minimum-1 sequence
of current items sequences (max if tree has editable="bottom", min if tree has
editable="top").

This will allow to speed up our migration platform: as funzip can pipe
the output of the first file of the archive, even if the file is not
fully unzipped yet. This is useful to plays with dump.sql without waiting
for the full archive decompression.
When a `noupdate` record is processed during an update,
the update_dummy method marks the record as "seen" so
it won't be deleted at the garbage collection step,
and seen as an obsolete external ID.
This needs to be done also for the parent records via
_inherits, because they have also received an implicit
external ID at creation, and must not be garbage
collected, even if their `noupdate` flag (db side)
is not set because the flag was added later.
This rare problem could be reproduced by creating a product
in a module, then referencing it in e.g. a sales order,
then updating the module after changing the product
record to be in a `noupdate` block.
At the end of the update the implicit product.template
record would be garbage collected, and trigger a cascade
deletion of its children - blocked by the SO reference
to the product.
This temporary patch was used to simulate the presence of a
`display_name` field in all models. It is not needed anymore
as of version 8.0, which comes with the actual magic to make
`display_name` work everywhere.
