[IMP] Rounding not necessary

instead of using a custom lookup with a different implementation
closes #2608

pass context as a named argument

[FIX] sale_stock: packaging was given a product instead of a product template id, leading to possible crash or incoherent values.

[IMP] Add purchase order origin on picking

[WIP] Picking type on move for location on routing

[IMP] Provide extra function for custom buttons on picking

[IMP] Action assign optim

[IMP] Push apply should take invoice_state into account.  Propagation of cancel of stock moves should depend on procurement rule

- avoid using sale objects in stock_account module
- check the purchase side

[FIX] sale_stock: product_id_change_with_wh should not call another method (product_id_change) using super, but self. Otherwise some overrides are lost, leading to issues with event-related products.

[FIX] sale_stock: invoice createde from picking was not using the prive list from the bom components

A squashed merge is required as the conversion of the apiculture branch from
bzr to git was not correctly done. The git history contains irrelevant blobs
and commits. This branch brings a lot of changes and fixes, too many to list
exhaustively.

- New orm api, objects are now used instead of ids
- Environements to encapsulates cr uid context while maintaining backward compatibility
- Field compute attribute is a new object oriented way to define function fields
- Shared browse record cache
- New onchange protocol
- Optional copy flag on fields
- Documentation update
- Dead code cleanup
- Lots of fixes

sale_order module override state field of sale.oder (sale.sale.py) and forgot to reset the track_visibility, therefore sale orders state changes are no longer tracked once this module installed.

[FIX] sale_stock: comparing stock and sale order line qty is always done with default uom rounding precision

Like it should do, the feature was broken
Moreover, it resolves a performance issue (do with 100 lines took up to 10 minutes)

[IMP] procurement: removed the schedule_range field on res.company which was error prone and not really usefull + made the scheduler run in SUPERUSER to avoid intercompany and access rights issues + made the run of procurement as SUPERUSER too for the same reasons

[FIX]sale_stock: do not raise if not able to find any warehouse (for the get default warehouse), it can prevent the user of doing anything (if he does an upgrade of sale_stock module while having no warehouse set, the user will not be able to sign in in his instance again).

[IMP] pocurement, stock, purchase, sale_stock, stock_account: misc changes in usabilty, code refactoring and new option on procurement group propagation.
1) form view of procurement.order and procurement.rule reviewed
2) added buttons on procurement.order to jump on other procurements or pickings of same procurement.group
3) tracked some fields on procurement.order
4) used the short name of warehouse for the rule names
5) added a new choice for the procurement.group propagation in order to allow having only one reception picking for several po lines grouped in the same PO but belonging to different procurement.group at first
6) some code refactored for easiness, modularity, clarity and other obvious reasons

[FIX] stock, sale_stock: changed the way the procurements look for a suitable rule => Added a m2o field warehouse_id on procurement.order, procurement.rule and stock.move. There was a problem with MTO products because they weren't following the route of the chosen warehouse at all (since all warehouse were creating their rule in the same route, there was no garantee that the route chosen was included in the warehouse selected on the SO)
