Historically, it was possible to import addons via a naked import. It is
no more possible since 9e1f13bac, since that commit, the only possible
way to import odoo addons is via the `import odoo.addons' prefix.

This commit refactors calendar synchronization between Odoo and Google after the
main calendar application refactoring.

This refactoring takes advantage of two new features from the Google API:

- New way of synchronizing resources efficiently[1]
Incremental sync is performed repeatedly and updates Odoo with all the changes that
happened ever since the previous sync. Each time, Odoo provides the previous sync
token it obtained from Google and stores the new sync token from the response.

- Event metadata[2]
Ability to set hidden key-value pairs with an event, called extended properties.
These extended properties are used to store the related odoo event id and the Odoo
owner id (see known limitations)

Known limitations
=================
- Let A and B be two new users (no tokens available). A creates an event in Odoo and
invites B. A is the owner of the event (user_id). Now B authenticates to his Google Calendar
account and synchronizes his calendar. We cannot send the event to A's calendar since we
don't have any access to his Google Calendar. Hence the event his sent to B's calendar.
This leads to data de-synchronisation: The owner is A in Odoo but B in Google.
The "real" owner (user A) is stored in the Google event's metadata to be able to
reconcile the owner for following synchronizations.

- Let A and B be two users of Odoo and Google Calendar. And let the Google Calendar of B
be private (e.g. if A creates an event in Google Calendar and invites B, B won't see the
event in his calendar). If A creates an event in Odoo and invites B. The event is synced
to Google Calendar of A. Now B can see the event in Odoo but he can't see it in his
Google Calendar.

This commit introduce a full redesign of all JS views.  We started
basically from scratch.  The goal was to unify all the various views
under a common framework, to make them testable, to make then usable in
different conditions (in studio, or in the frontend), and to make our
lives easier.

Some important points are:
- we introduced new coding guidelines (camelCase, 80 chars width, ...)
- we have a brand new testing framework (still QUnit based)
- kanban view moved to the web addon
- calendar view (formerly web_calender) moved to web as well
- the tree view was removed
- all new code should be documented

We hope that this code is the start of a new era for the Odoo web
client, we want to have a high quality codebase, well documented, well
tested, well designed.

Work done by the framework team: mostly aab, ged, chm, dmo, qsm

No behaviour changes, only migrate code and add
some docstring.

We also remove the mock in web as there is no need for it anymore.

    - Use the new fields from calendar (renamed in 9398.1.7 trunk-cal-v8-jke)
    - Manage some google excpetions about token expiration
    - Manage some google excpetions about token revokation
    - Manage some google excpetions about 410 - Gone from google
    - Detect / Allow user to change the calendar and remove all old reference.
    - Use by default the since_modified for synchronization and not always a full (updatedTime in google)
    - Add some key for ir_parameters : 
             'calendar.week_synchro' : number of week to synchornize when we are in full mode
             'calendar.block_synchro_attendee' : need to synchronize the attendees between google and openerp (creation of partner)
             'calendar.block_since_synchro' : Always use the full synchro. (Can be forced in "one time" removing the last synchro from res_users form)
             'calendar.debug_print' : _logger is more verbose
    - Pep 8
    - Change behaviour of do_request to return a tuple with status raquest and response
    - Add field from token and synchro date in res_users view form

Remove 2 unsused field from calendar.event model (dir,sequence)
