This replaces the former modified preorder tree traversal (MPTT) with the
fields `parent_left`/`parent_right`.  Each record is associated to a string
`parent_path`, that represents the path from its root node to itself.  The path
is made of the node ids suffixed with a slash:

              a                 node | id | parent_path
             / \                  a  | 42 | 42/
           ...  b                 b  | 63 | 42/63/
               / \                c  | 84 | 42/63/84/
              c   d               d  | 85 | 42/63/85/

This field provides an efficient implementation for parent_of/child_of queries:
the nodes in the subtree of record are the ones where `parent_path` starts with
the `parent_path` of record.  It is also more efficient to maintain than the
MPTT fields, and less sensitive to concurrent updates, because the value of
`parent_path` does not depend on sibling nodes.

Simplify the implementation of parent_left/parent_right by removing this
optimization.

Simplification of the search method of the lines lines (for the
propositions) of the two requests in one. The sql query returns the two
matching lines without filtering after the request because we inject the
rules of access rules directly into it.
This is an optimization in terms of clarity and speed. In addition to the
fix because the previous browse does not use access rules.

Contains widget reconciliation methods. This refactoring does not modify
the feature, some errors have been notified in the code but not modified.

The following tweaks have been applied on mobile devices:

 - remove left and right arrow in control panel
 - enable swipe navigation (instead of left/right arrows)
 - replace 'Today' button by a calendar icon
 - remove static text 'Attendees:' in events
 - shorten header content in week mode to prevent them from
   overlapping
 - ensure that the calendar fits in the screen

Also introduce a mobile test suite for the calendar view.

[IMP] account, account_bank_statement_import: create res.partner.bank only when statement lines get processed

Previously, bank accounts were created at the line creation, even if the partner was unknown. That was a very weird behavior since
- that use case of a res.partner.bank belonging to no one is meaningless
- the default partner was actually set to the current'user company, which was even more wrong.

This has been already improved by https://github.com/odoo/odoo/commit/7b322d08de2b5343cdf6935a7ae4a12f1fd61958 but that first patch ignored the use case of res.partner.bank created thr$

Currently the rating value coming from the rating application is stored
on the message it belongs to. However storing it is not necessary as
there is no direct search using it. Having a computed field is sufficient
for all use cases we currently have in Odoo.

Removing the store allow to gain queries. Indeed the field is not
computed anymore after each message creation meaning we save queries
by not having to check existing ratings. It allows to gain a lot of
computation as mail.message is a critical model.

On the whole community runbot when installing all modules this leads to
a gain of more than 14K queries on 585K which means 2.4% of performances
increase. Considering the code size of this optimization this is quite an
interesting result.

Looking at test_mail performance tests we gain several queries (2/3) for
each new message which is coherent with the model change.

Finally it allows to lessen the performance difference between tests done
with test mail only and tests done with other modules already installed.
This is especially simple mail thread-enable records.

Related to task ID 51523. #Closes #23294. Done with blessing of @jem-odoo .

Also rename product.uom.categ into uom.category to
 give it a decent name.

Moves UoM models, test and data to a new addon in
order to be able to use uom without product.
A simple example is be to be able to use UoM for
timesheets.

This commit only move code, and adapt xml ids
without chaging any feature or functionnal
behavior.
Note: 'product' module now depends on new
'uom' module.

Purpose of this merge is to clean a bit various methods and remove some
dead code. All those commits come from other work-in-progress branches
in mail aiming at improving performances and reducing code size. We can
already merge some light cleaning in order to lessen diff and ease
understanding of real feature-based branches.

It contains

 * some renaming in notification methods to match the _notify prefix used
   in most of them;
 * removal of  some dead code coming from old implementations of chatter;
 * removal of unnecessary context switch in email sending process;
 * small cleaning of notification group methods in various addons;

It allows to gain some queries in various test_mail performance test as
stated in the test_performance file update. When notification emails are
sent 4 queries are gained with this merge. On the whole community runbot
the impact is small (about 1K queries) probably because most of email
sending part is skipped on runbot.

This merge is related to the task Id 59039. #Closes #23089.

Overrides of _notify_get_groups are used to add some buttons in notification
emails and control the display of "Access document" button. This commit
cleans some overrides :

 * accounting: portal users that are not the customer have no access to the
   invoice and should not have the access button;
 * project: remove unnecessary override on project model and consider portal
   users have access to the document through customer portal;
 * sale: portal users that are not the customer have no access to the sale
   order and should not have the access button;
 * website_blog: display access button to everyone only if the post is
   published; otherwise keep standard behavior;
 * website_forum: display access button to everyone only if the post
   has not been closed or deactivated; otherwise keep standard behavior;
 * website_slides: display access button to everyone only if the slides
   has been published; otherwise keep standard behavior;

Send methods of mail.mail model are set private and simplified. Those
methods have been written when a lot of overrides were necessary to
generate notification emails. Since then the flow has changed but
methods have not been updated completely. This commit therefore simplified
a bit the call chain and parameters.

This commit is purely technical and does not hold any functional change.
Purpose is to clean code in order to prepare future changes in mail
application.

This commit renames some internal mail.thread methods linked to the
notification process. This is the next commit of a series aiming at
improving code readability and method finding through prefixes. See
notably cae1c397, cdfe479e and fc1348dd.

This commit does not change any functional feature. It does only
rename notification-related methods, using the _notify prefix to
ensure they are private and to mark they are part of the notification
process.

Commit 0d3d0e95 added a key in context when sending emails to know
the target model name. It was used at that time to forge for footer of
notification emails.

Since that time notification emails have evolved a lot. The code based on
that context key has been removed. Context key has been transformed into a
context switch. However it is not used anymore and can be removed. It allows
to clean a bit the code and save a context switch.

This commit is purely technical and does not hold any functional change.
Purpose is to clean code in order to prepare future changes in mail
application.

This commit allows to gain some queries in mail sending process, meaning
removing context switch is interesting. One query is gained when using
the send process. Complex performance test involving several message post
gain 3 queries each.

1d57a091 added a two-steps parent fetch when posting a message
on a discussion thread. At the time this commit was done responsible were
notified of the first thread message. It was helpful to notify them of the
original email that created the thread instead of the "document created"
generic message. Indeed for documents like leads or issues having the
original email containing the customer question is interesting when being
notified. This is why this commit was done.

However since quite a long time responsible notifications have changed.
They now receive an email notification telling they have been assigned on
a document. This commit is not necessary anymore and we therefore remove
it in order to clean a bit the message_post process.

This commit globally reverts 1d57a091. Please note that @beledouxdenis
agreed after a long thinking.

This commit has a slight impact on mail performance tests, allowing to save
one query in some more complex test case.

Purpose of this commit is to simplify a bit message_post API. It has
a content_subtype parameter allowing to receive plaintext content.
It is then automatically converted into html.

This commit removes the parameter and consider the content is always
html. Code calling message_post should handle the conversion. In Odoo
the only use was in the chat_post controller that now perform the
plaintext to html conversion before calling message_post.

This commit is purely technical and does not hold any functional change.
Purpose is to clean code in order to prepare future changes in mail
application.

Posting on users is not supported anymore. It was implemented in a time
we thought having a twitter-like behavior in Odoo was a good idea.
Posting on users was redirected on its related partner in mail. It was
redirected on its related employee in hr. It does not make sense anymore
as employee are records with limited access and partners used for other
purpose than discussing notably in accounting.

Now that we have chat channels it makes no sense to have this kind of
behavior still implemented. Let us remove it. No functional change
should occur with this commit.

Propagation was not correctly done at 8a026e26 . This commit
ensures all parameters are passed to sub-calls when redirection is done
in message_post.

A test_mail only counter was not updated correctly after changes done
in user assignation notification (see a6e13248).

`Archive` feature has been removed with e5330857

For objects inherting from rating.mixin, when their parent model change
(e.i.: task from a project to another), the "Parent document name" does
not change. The rating is still considered belonging to the old parent
object (rating stat of project is not correct).

Change the rating API. In rating mixin, instead of having 2 methods
returning parent id and parent model (rating_get_parent_id and
rating_get_parent_model_name), we should have one method returning the
'parent relation field' (inevitably m2o field). Then we can deduce its
parent_res_id/parent_res_model, and check this parent field is in values
of write to trigger the recompute of parent_res_name.

Also, add "ondelete=cascade" on parent_res_model_id

Impacted modules: project, rating, helpdesk, livechat

It shouldn't happen, but if we change the name of multiple rating_mixin
inheriting models, we can run into an error, because write doesn't
support multiple values.

The nocontent helper can be generated either statically (in xml)
or dynamically (in python).

Before this commit, the result of some nocontent helpers was simply
the concatenation of the static and dynamic parts.

Due to recent changes (see https://github.com/odoo/odoo/commit/a87d761fdbf345ada5dc93e0a686b08a0f5a0417),
the nocontent helper has changed so that any of the nocontent helper
parts has to define its style for showing the face (e.g. smiling,
neutral, or folder face).

As a consequence of the changes above, the styles of some
nocontent helper screens were duplicated, e.g. two smiling faces
were shown instead of a single one.

With this commit, most dynamically generated nocontent helpers keep
only the dynamic part, so the static part is usually dropped in this
case.

Exception to above rule:

    dyn_help = 'You could also add a new [document_name] by sending an email to [email_link]'

The dynamic part is appended right after the static help message, in its dedicated paragraph.

Before this commit, on a clear session, there was a traceback
after focusing out the emoji button next to the composer.

This is due to a DOM element that exists only after clicking on
the emoji button, and it was wrongly assumed that focusout cannot
occur without a preceding click. Indeed, we can press TAB to move
between focusable elements, so that we can have the focus in/out
on the button without clicking on it.

In particular, qunit 2.3.0 solves this issue: https://github.com/qunitjs/qunit/issues/1119

A consequence of the above issue is that some tests could have completed successfully,
although an error was raised.
