* Remove AST in favor of pure Pyhon. This should make it easier for
developers to understand and create new directives because they do not
need to know AST.
* Remove `t-call-options` as it has been merged into `t-options` for more
consistency. Support for t-call-options is retained.
* Use generators for lists. This increases performances as the rendering
can be sent directly without having to wait for the creation of the
entire list.
* Optimize expressions runtime computation by pre-computing the static
parts.
Example:
'<' + 'div' + '>' + '<' + dynamic_value + '>'
Now compiles as:
'<div><' + dynamic_value + '>'
The new "image_url" widget logic provides the ability to provide static image
links in Char fields instead of duplicating the image file in database (+ filestore)
through an Image field (& ir_attachment).
This commits implements the frontend qweb logic for this widget, following the logic
of the existing "image" qweb widget.
PURPOSE
Before this commit, when you used the 'image' widget when the record name was
``..`` (double dots) it couldn't retrieve the image since the double dots was
decoded as the parent directory shortcut. After this commit, the double dots
will be replaced by -- with the downside to loose the true record name.
SPECIFICATIONS
Replace the .. (double dots) with -- in the filename.
Using .. may seem like a strange use case but if you actually try to find
a partner called ".." in a production database, you might be surprised ...

Take the following QWeb snippet:
```
<div t-field="product.image" itemprop="image" t-options="{'widget': 'image'}"/>
```
When the image is rendered, the `itemprop="image"` remains on the
`<div>` tag, it is not set on the `<img>` tag.
We add the support of the `itemprop` option, so it can be added to the
`<img>` tag:
```
<div t-field="product.image" t-options="{'widget': 'image', 'itemprop': 'image'}"/>
```

SHA-1 is a cryptographic hash function that have weaknesses known since
2005, it has been deprecated by the NIST [1] about 10 years ago in 2011
and Google [2] have been able to perform a collision attack in 2017.
We use SHA-1 in order to generate unique URL for resources that can be
cached by the browser: assets bundle, translations, qweb templates and
qweb images.
Although practical attacks still requires quite a lot of computational
resources, it is time to upgrade SHA-1 to SHA-2.
We have selected the SHA-512/256 variant of the SHA-2 algorithm as
replacement for SHA-1 for the following reasons:
* On 64 bits platform, SHA-512 is the fastest SHA-2 variant, it is only
~1.5x slower than SHA-1. [3]
* Keeping only the 256 foremost bits protects against both collision
attacks and length extension attacks.
* The hexadecimal digest is only 24 chars longer than SHA-1 which is
nice to have somewhat short URLs.
We have not used SHA-3 because:
* At the moment of writing, it is too slow (~3x slower than SHA-1) [3]
* It is not guaranteed to be available with the Python 3.5 `hashlib`
module.
* One of the author of SHA-3 is Belgian.

The images that are resized have additional borders if the target ratio is
different than the image ratio. Those borders are transparent if the image
format supports it, and are white otherwise.
With that current solution, if the background where the image is displayed is
another color than white, it is looking really bad.
Moreover, most images are stored resized like this, so it is not even possible
to decide if it should have borders or not depending on the context, the
original image and ratio is forever lost.
It is also inconsistent because if the image is already smaller than the target
size then it doesn't include borders. In that case it keeps the original ratio
instead of the target ratio. So it isn't even guaranteed that the target
ratio is going to be respected.
After
=====
This commit will solve all of those problems by always keeping the ratio of the
original image.
This implies the views should be taking care of adding borders when necessary.

It's better to always have a relevant name in the image URL for SEO.
Also make sure there is always an alt on the image.

With this option we can define which field is going to be displayed by the qweb
image widget, while logic is still applied to the original field.
For example, we want to show a thumbnail image but when user updates it with the
web editor, we want to update the actual field instead of the thumbnail field.
This is similar to the preview_image of the JS image widget.

This commit replaces calls to pycompat helpers that were intended for
python 2 <-> python 3 interoperability for python 3 builtins, as python
2 is no longer officially supported by Odoo.
This includes:
* calls to imap/izip/ifilter replaced by map/zip/filter
* uses of text_type replaced by str
* uses of unichr replaced by chr
* calls to implements_to_string, implements_iterator removed
* string_types and integer_types replaced by str, int respectively
* calls to to_native replaced by calls to to_text
This is done in preparation to the removal of these deprecated helpers
in the following commit.
Purpose of this commit is to give description more "business oriented"
because those descriptions appears in Odoo Studio which is supposed to be used by end users, not only by developers.

- If a CDN is used, this might cause issues for images that need access
rights to be display.
This is due to the fact that users are not connected on their account
under the CDN domain, which makes the CDN requests reject since it is
not authorized to access to those resources.
From this commit onwards, Date fields will return datetime.date objects and Datetime fields will return datetime.datetime objects, this implies a number of things that are clearly explained both in the ORM API for master.
This commit also introduces a number of helper functions for dates and datetimes that are exposed in tools.date_utils and fields.Date[time], explained in the documentation as well.

Before this commit there was no option to avoid resizing images when it
was smaller than expected size. This leads to several image being displayed
with extra and unnecessary padding due to resize. This option will allow
to avoid that behavior by allowing to propagate the parameter directly
to image_resize_image.
This commit is related to task ID 31994 .
Currently the image field rendering in QWeb using the /web/image
controller is done in web_editor. However there is no link between
the web editor and the rendering. The rendering can therefore be moved
directly in web.
During the move two options have been added to the rendering of image
field :
* qweb_img_raw_data: fallback on standard base64 behavior that is
otherwise impossible to achieve;
* qweb_img_responsive: True by default, add the img-responsive
class that is not always requested;
Thanks.
