When installing website or one of its dependencies directly, the website
attribute is not defined on request. If the installation triggers qweb
rendering [1], we need to correctly check the presence of the website
attribute, which this commit does.

[1]: This is the case in website_blog since
4a132e2a

This reverts commit 44e8b92b.

The condition is wrong as a view starting with DOCTYPE as top element will be
excluded, including its child (the whole page them).

Re-add the translatable title that was excluded by the condition.

[FIX] *: replace uses of `except_osv` with `UserError` that have been forgotten during previous forward-ports

Give the same as access rights to the employee as for the public user.
This patch is needed to allow a user to access the partner form.
Same for portal.
The list of grades in not a confidential information.

Fixes #7719

When the admin creates a SO, he has access to all taxes (since ir.rules
do not apply to him); therefore in some cases, the SO could be created
with SO lines that have taxes from other companies. This usually does
not make sense.

From this revision on, only taxes that are in the same company as the
SO are applied to the lines. If no company is set, then no filtering
is done.

This is a fix for f04f4099, which only
prevented the workers from being spawned in Prefork mode, while the
socket was still being bound to - this is a problem when starting a
worker-only server as it cannot coexist with the XMLRPC server on the
same machine.

UserError was defined in version 9, not 8

When merging leads with a company set different
than the current user company,
it failed because the notification email (the message
written in the thread summarizing the merge) couldn't
read the company name (the `name_get` call on the company)
because of the multi-company record rule.

`name_get` can be safely called as `sudo`, as it does
nothing else than returning the name of the record. This is
already done for the many2one links in the web client anyway
(You can see leads from a company different than yours,
you can see the company name to which the leads belongs to,
but you can't click on the company many2one link)

When sending a notification email to an event attendee
for an all day event, the timezone must be ignored
as the `start` and `stop` datetime are stored as
the day date + '00:00:00'. If the timezone is applied,
for users being in a negative timezone (such as an American
timezone), the day displayed would be the day just before.

When computing the real price of a product, a currency of reference is
needed, first the currency of the product's company is privileged and
if no company is set on the product then the currency of the user's company
is taken.

Fixes #8545

When a user has the access rights "Configuration" or "Access Rights"
regarding the "Administration" module category, the click on the
"Settings" menu leads to an access error.

This is because the dashboard fetches data about the number of installed
modules ("installed_apps"), which requires access to "ir.module.module".
Since it is not easily possible to hide a parts of the dashboard (the
static templates do not recognize the "groups" attribute), we simply
hide the dashboard for these users.

[FIX] account: don't write the foreign currency on writeoff when several secondary currencies are involved

Quants are created, and stock moves are updated, with the purchase
value converted at current rates.  However, the product average
was calculated before that value was retrieved.  This ensures
the correct value is retrieved for the average cost calculation
and will match the actual quants.

The get_recursive_parent function seemingly depended on the ordering of
the rule_categories recordset which happens to work fine in most cases
because all data first defines the parent before defining the children
rule categories. But if you happen to do it the other way around it
won't work and it will infinitely call itself because:

if rule_categories[0].parent_id:
    rule_categories = rule_categories[0].parent_id | rule_categories

won't change the value of rule_categories[0].
