Hardcoded reference skips the mapping (company, template) -> account.account leading to key error.

Steps to reproduce:

-Go to accounting dashboard
-Click on "More" in vendor bills dashboard
-Click on "bills analysis"

Bug: it opened the account.invoice.report view, which crashed.

Reason: The function get_names in addons/product/models/product.py got an empty record set
product.category(None,) and returned [False] so when joining " \ " with [False], it crashed.
The empty record set was returned  when the categ_id of an account.invoice.report() was None.

Commit 906875fc (followed by commit
76be5eed) tried to tweak to copy/paste
functionality of the editor.
Indeed, in PDF file, when copying a paragraph, a line feed is added at
each forced line break (page width end). This forced a line feed and
a new paragraph in the pasted text. The goal was to get rid of those
useless linebreaks when pasting.

The ideal solution would be to detect that the text was copied from
a PDF but it is not possible. However, this commit improves the
heuristic: if this is not plain text, then nothing is done, the content
is pasted normally. If it is plain text (like when copying from pdf),
then each line break which is surrounded by letters or numbers is
considered an useless line break and replaced by a space. This is
obviously not perfect but the previous implementation was really wrong
(it was removing line breaks which were not preceeded by punctuation in
all cases, which was removing lots of useful line breaks).

Note: this commit also fixes a bug -> text was not able to be pasted
with Internet Explorer.

This commit partially reverts 5b4f7c13 where `fields_view.fields`
had been replaced by `fields`, which could have been set to all
fields in the model.

This modification can sometimes lead to a problem, during the
fields value transformation. The ID, which wasn't given previously
is now parsed. When creating a new record, the field ID is not an
integer but a string (representing the virtual ID). If the field
is in the arch, it will be postprocessed
(see https://github.com/odoo/odoo/blob/saas-11/addons/web/static/src/js/framework/data_manager.js#L201)
and its type will become `id`. As this postprocessing is not done
if the field in the view, the parsing was on the original type
(integer) and not the special id type.

- Create an invoice with two products
- Each line has a long description (spread on 2 lines)
- The second line has a negative value
- Print the invoice (PDF)

The amount spreads on two lines, split as:
$ -
1,000.00

This is due to the wkhtmltopdf version with patched QT. Unfortunately,
upgrading to the latest version 0.12.4 doesn't solve the problem.

The solution is to replace the '-' by a non-breakable hyphen.

Fullcalendar expect as `start` and `end` property of an event object:

> When specifying Event Objects for events or eventSources, you may
> specify a string in IETF format (ex: "Wed, 18 Oct 2009 13:00:00 EST"),
> a string in ISO8601 format (ex: "2009-11-05T13:15:30Z") or a UNIX
> timestamp.

(as seen in https://fullcalendar.io/docs1/event_data/Event_Object/)

Before this commit we could for example in arabic provide an invalid
date string "٢٠١٧-٠٣-١٦ ١٦:٠٠:٠٦" instead of "2017-03-16 16:00:06".

This commit solves this by always providing fullcalendar an ISO8601 date
string.

The transcoder (which transforms stylesheet rules to inline style) did
some compression of the padding and margin css properties to not always
have margin-top + margin-right + margin-bottom + margin-left.

This could cause an issue when the value of margin or padding contained
an initial or inherit value because browsers (at least firefox and
google chrome) doesn't allow it. Thus the preview could for example have
bigger veritcal spaces arround `<p />` tag than what was seen when
editing.

With this fix instead of invalid:

    margin:initial initial initial initial

we have:

    margin:initial

And instead of invalid:

    margin:initial 5px 6px 7px

we have:

    margin-top: initial; margin-right: 5px; margin-bottom: 6px; margin-left: 7px;

It is still possible to have negative and positive quants in the same
location because of returns: if you send something to the customer that
is not there and you return it, you will still be able to reserve the
returned goods to send to another client.

Before, if you would do an inventory adjustment, it would not take into
account these returned quants and their negative counterpart, which made
them difficult to get out of the system.

This fix takes them into account by creating two movements for one
inventory line: move the positive counterpart to the inventory location
before getting back from this location the same quantity.

This way, even if you have 0 as quantity on hand but you have those 2
quants, it will eliminate them. (if you are increasing the stock, part
of the process might have done it automatically already).

We sometimes use in Odoo a One2many field with an inverse Integer
field instead of a usual Many2one.

This allow for example in several instances to have a "Many2one" which
can be reference from several models, eg:

Model Ranking:
	name = String field
	res_id = Integer field
	res_model = String field

Model Toy:
	rank = One2many [inverse: Ranking -> res_id]
                        [domain: res_model == Toy]

Model Tool:
	rank = One2many [inverse: Ranking -> res_id]
                        [domain: res_model == Tool]

This enable us to have a shared feature between otherwise unrelated models.

But there was several issue when searching on these One2many:

1) if the Integer Many2one was not stored (eg. it came from an inherits) on
   the searched model, this could lead to an error.

2) when we searched:

   - by IDs (rank in ['55']) with at least one id not respecting the domain
   - by IDs with a negative operator
   - with a negative operator on unfound string (rank != "no rank has this")
   - with a false value (rank = False)

   we would not apply the One2many domain (eg. res_model == Toy) and thus
   possibly getting Toy 3 errenously because a Tool 3 was found without
   the domain being applied.

This fix modify the search on One2many and for:

1. if the inverse is an Integer not stored field instead of Many2one
   manage it.

2. if the field is an Integer field instead of Many2one and there is a
   domain on the One2many: apply the domain on the inverse model found.

So only some search on One2many with a domain whose inverse field is an
Integer could be impacted.

This would also be nice to have for all One2many with a domain but the
probability of it being useful versus risk for performance is not judged
high enough.

Commit 00bd7274 introduced speed improvements when
sending emails through batching and reusing an SMTP connection for a
given batch.

However exception management was slightly changed during that patch.
Previously to this patch all errors in the sending process were considered
as MailDeliveryException, except for MemoryError and psycopg errors.
However now mail_mail.send() may raise another kind of exception in the
SMTP connect process. Moreover a raise_exception parameter allows to
choose to either raise an exception, or just set emails in exception
state without raising an error. However since the patch it is not taken
into account correctly.

This leads to several issues, notably

 * auth_signup waits for a MailDeliveryException when sending a password
   request email. A badly configured SMTP server leads to a connection
   error that is not caught. This prevents creating users, which could
   be annoying.
 * chatter does not handle exceptions as notification emails are sent
   using raise_exception being False. Having an issue in the connect
   process crashes the chatter.

This commit fixes the exception management so that it behaves like
before the patch.

- Create Product A with a BOM which depends on a product with tracking
  "By Unique Serial Number" (Product B).
- Create a MO for Product A
- In the "Register lots" wizard, add two lines for "Product B", with the
  same serial number.

Nothing prevents the user to do it, even when the inventory is posted.

When unlinking an ir.model, all the ir.model.constraint linked to this
ir.model must be removed to avoid to call unexisting model.

In stable version, the right fix would be to put an attribute ondelete=cascade
on the field model of ir.model.constraint.

In 10.0, the ir.model.constraint are created with module = the module where the related field
has been declared. But when unlinking the ir.model in function _module_data_uninstall, the related
ir.model.constraint to remove were chosen according to the removed modules. So with models
declaring constraints on inherited fields, some problems occured because the model could be removed
and not all the related constraints.

Public users were stuck at the extra step during the checkout

When we are trying to change the reception route of a warehouse when

When creating a stock.picking, the related fields picking_type_entire_packs and
picking_type_code were both updated.
This was an issue was required write access on stock.picking.type (warehouse
manager) to create a stock.picking (warehouse user).

The fields were updated as they were present in the view and filled with the
related value. Even if the value was unchanged, it was triggering a write
anyway.

The two fields were in invisible="1" and used only in attrs for other fields.

Making these two fields in readonly does not prevent to use it in the attrs but
avoid to send a value to the server and trigger a useless write.

Fixes #15769

When an input is saved with an invalid value, it gets the
`o_form_invalid` class. This makes the border red. In enterprise, there
was a bug as required inputs have also a different border color and the
rule was more important. Unfortunately there is no avoiding
the !important rule here. Indeed, other solutions would require to make
more rules in enterprise or to change the order of files (which would
create many problems).

Setting a max-height on the tags section is not a good idea ; this
causes the tags to overlap the record.

If something (like a text) is put in the section instead of the
tags, the height is not correctly adapted.

In the kanban view, if we try to group by a selection field that is
not defined in the arch, the key will be used as column name (instead
of the string).

A fix has already been pushed to load all the fields in this case
(see 0e6eb968) but these fields were not correctly used in this
particular case.

Since commit ee2c76a4, `journal_entry_ids` is an `account.move.line`,

Closes #15799

When a sale order is created from the interface, the name field is read-only so
not given in the create call.

However, if the create values are filled with the default value, the string
'New' is translated and the condition is not met in the create method.

This commit makes the create consistent with the default `lambda self: _('New')`
