Added tests to try to test this behavior.

QWeb monetary widget uses the precision of the currency to know the number of
digits to display on a price. The number of digits is based on log10(rounding).
For currency with rounding different than 10^x (e.g. in Switzerland 0.05
to allow 5 cents coins only), the number of displayed digits should be rounded
up. e.g. log10(0.05) is -1.3, rounded up to 2 digits.

Fixes #3233

requested by fp. the filter is wrong and not very useful from a
functional viewpoint.

This fix is related to c12a2e1d

Mutex allow to wait sequentially for mutex
Besides, if one of the onchanges deferreds fails, it does not resolve the mutex until all deferreds of the mutex are resolved.

Besides, we now wait for the onchanges mutex between each field commited value (line 596) in case the commited value leaded to a new onchanges, that we should wait for before commiting the rest of the values.

Closes #3902

- better many2one ondelete strategies
- domain set on fields, not views
- added domain on analytic_account_id field

fixes #3102

For instance, when a context was passed to a method, but no lang was defined in the context, it did not tried to fallback to other places where we could have find the user language.

In graph views, fields from the pivot table were not translated in the user language
We pass the context, containing the user language, to fields_get in order to get the translation
This is also done by the search view, in search.js line 1978 at this rev.

In multi company environment, the company logo was not updated on company change in the user preferences
This disrupted the end user, as he might think the company change did not happen.

Without this fix, if you have a new view in a module with active=False, the active tag will be ignore when upgrading the module because of 'update' mode, and the view will be activated by default !

Incorrect use of stock.move in product module + needs review.

This reverts commit 42f51140:
"[IMP] When no stock moves, change whatever you want, otherwise no change at all for UoM.  #3440 Enhancement request richard-willowit"

[IMP] When no stock moves, change whatever you want, otherwise no change at all for UoM.  #3440 Enhancement request richard-willowit

The default UoM can only be changed when there are no stock moves (or only cancelled ones), but to any category.
The purchase UoM can be changed whenever you want, but has to be in the same category as the default UoM.

Closes #3440

[IMP] When no stock moves, change whatever you want, otherwise no change at all for UoM.  #3440 Enhancement request richard-willowit

[FIX] Remove line

[FIX] Constraint should be applied when UoM or PO UoM is changed

[FIX] website_forum: Forum, use old API in v8. forum was not a browse record, so we need to re-browse. Tags: Force to delete tag. Before old tag deleted was not removed from relation, Now we use a 6 to force the update, followed by 0 to create.

Otherwise, in some cases, the categ_sequence can be set to null, which is not ordered the same way than 0, and you won't be able to sort lines with null and 0 as categ_sequence between each others

Used to be rounded to integer while the field is a float.
Fixes #3526

POS is loading all partners, not only customers

Replaced domain functions with literals where there are only constants

When adding informational attribute, with only one possible value, it used to be skipped.
Instead keep it and add it on every variant.

To avoid dropping and recreating product (and lose eventual customisations), the attributes with only one possible value are set on every product.
This makes sure that in following test, these are not considered in variants_inactive variable.

Fixes #3204

[Fix] ir_translation: fix the problem of base_field object has no attribute model (Maintenance Case:618054)
