Use case:
When the server is restarted, the python is updated,
but some users may have an ongoing session in a browser tab
This may lead to code being unsynchronized and ultimately to some
odd bugs.

Purpose:
When we are in such a case, that is, the assets were recomputed
after a update of the code and a restart of the server by the request of another user,
notify connected users that assets have changed.
Then propose them to reload the page.

Known caveats:
- This is not a developer's feature.
Since assets computing is ORM cached, they have limited
opportunities to rebuild. Namely, the feature won't trigger
each time the JS has changed, rather, it will
when JS has changed AND the cache has been reset somehow (e.g. when the server is restarted).

- This not a portal/website feature either, but only in backend.
Business clients won't be notified that the JS has changed.

- While requests debug=assets do trigger a recomputing
of the *components* of bundles, they do not save a bundle
This means that the requests that sends the notification
cannot be debug=assets.

render, render_template, load, activity_schedule_with_view,
get_website_pages should all be private:
It should not be possible to render an aribtrary template only with
its name or id

Still need to render some qweb views from js so the method
render_template is kept public.
This explains why the website editor still need read access on
ir.ui.view as we want to allow any snippet to be rendered.

Purpose
=======

The current kanban view is messy. It is difficult to identify which
apps are installed or not. The user can completely miss a module
that might have interested him. A search panel would make things way
more readable.

load_lang was a kind of hybrid method trying to active or creating a
language if not found. This was error prone.
Instead rely on two methods with clear purpose:
ResLang._create_lang(lang, lang_name=None)
  - create a new res.lang entry using the locale of the server
    return the res.lang record to match the API of _activate_lang

ResLang._active_lang(code)
  - activate the given code lang

Most of the time, _active_lang is what is expected

tools.trans_load_data and IrTranslation._load_module_terms no longer
activate the language if not active.
Loading the translations should be explicit on an activated language,
it is too error prone to silently activate/create a language if not
found.
Remove lang_name from trans_load_data as no longer needed.

When loading a page on an existing starting database, registry is not
fully loaded causing potential error when trying to access model
existing in database (views, menitem, ...) since model added in last
loaded module does not exist in registry.

Thus, executing browser js test may lead to errors when executed during
an update on a database with other modules installed.

HTTPCase should be executed post_install to ensure that registry is
fully loaded to avoid this problem.

Since HTTPCase are slower than other test, it is also a good idea to
execute them at the end, in order to prioritize fast fail.

With this commit, a warning is isued if such a test class is tagged to
run at install time.

While at it, remove deprecated at_install and post_install helpers and
remove the deprecated phantom_js alias.

PEP-594 is deprecating a bunch of modules. As part of the cleanup, we
are also dealing with long deprecated modules, functions and aliases.

* `assert_` -> `assertTrue`
* `assertEquals` -> `assertEqual`
* `assertNotEquals` -> `assertNotEqual`
* `assertAlmostEquals` -> `assertAlmostEqual`
* `assertRaisesRegexp` -> `assertRaisesRegex`
* `assertRegexpMatches` -> `assertRegex`
* `base64.encodestring` -> `base64.encodebytes`
* `base64.decodestring` -> `base64.decodebytes`
* `inspect.getargspec` -> `inspect.signature`
* `inspect.formatargspec` -> `inspect.signature`
* `logging.warn` -> `logging.warning`

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.

get_installed and _lang_get_id are both ormcached and correctly check
the context

Retrieving a res.lang from a code is a frequent action that can be
achieved with _lang_get (cf previous commit).
Using _lang_get ensure the active_test in the context is correct and
is not poluted with another context propagation issue.
odoo/odoo#35490 discussion is an example of bad context propagation

Multi is the default api for methods, it is not necessary to explicitly
decorate methods with it, adds clutter and most people use it because
they see that the rest of the code uses it.

Done with `find . -type f -name '*.py' | xargs sed -i '/@api.multi/d'`

Future runbot improvement may share sources between build,
meaning that sources will be readonly to avoid any interaction.

_touch() was supposed to handle ro filesystem but
f7130556 introduced a new test that was not working
in this case.

Instead of trying to touch file and pseudomocking the result
if the filesystem is readonly, this commit add a real patch
on getmtime.
