The 'scrap_img_by_id' function didn't return any longer anything useful. This
fix allows the google images engine to present the full source image instead of
only the thumbnail.
The function scrap_img_by_id() is rpelaced by a fully rewrite to parse image
URLs by a regular expression. The new function parse_urls_img_from_js(dom)
returns a mapping of data-id to image URL.

Previously the preferences & stats templates contained the markup:
<a href="{{ url_for('index') }}"><h1><span>SearXNG</span></h1></a>
There are many things wrong with this:
1. the markup was duplicated
2. the CSS needed to be changed whenever a new page wanted to use this
header (since the CSS used page-specific selectors)
3. h1 should be reserved for the actual page title
(e.g. Preferences or Engine stats)
4. the image was set via CSS which also set:
span { visibility: hidden; }
which however removes the alternative text from the accessibility
tree (meaning screen readers will ignore it).
This commit fixes all these problems.
Other optional parameter ..
`&sort=crawl_date`
can be appended to search_string to sort results by date.
`&domain=example.org`
can be implemented to search_string to get results from just one domain.

Currently we have two kinds of user documentation:
* the about page[1] which is written in HTML and part of the web
application and can therefore link instance-specific pages
(like e.g. the preferences) via Jinja variables
* the Sphinx documentation[2] which is written in reStructuredText
and cannot link instance-specific pages since it doesn't know
which instance the user is using
The plan is to integrate the user documentation currently in Sphinx
into the application, so that it can also link instance specific pages.
We also want to enable the user documentation to be translated.

The implementation of the etools engine is poor. No date-range support, no
language support and it is broken by a CAPTCHA.
etools is a metasearch engine, the major search engines it supports (google,
bing, wikipedia, Yahoo) are already available in SeaarXNG.
While etools does support several engines we currently don't support directly,
support for them should be added directly to SearXNG if there is demand.
In practice: in SearXNG the worse etools results will be mixed with good results
from other engines we have (as long as there is no captcha).
At best case, what we win with etools is in e.g. results from de.ask.com in a
query from a german request .. in all other cases worse results are bubble up in
SearXNG's result list.

The previous implementation used two hash sets and a list.
... that's not necessary ... a single hash map suffices.
And it's also less error prone ... because the previous data structure
allowed a setting to be enabled and disabled at the same time.
Previously the default_value was abused for the cookie name.
Having SwitchableSetting subclass Setting doesn't even make sense
in the first place since none of the Setting methods apply.
The ? search operator has been broken for some time and
currently only raises the question why it's still there.
## Context ##
The query "Paris !images" searches for "Paris" in the "images" category.
Once upon a time Searx supported "Paris ?images" to search for "Paris"
in the currently enabled categories and the "images" category.
The feature makes sense ... the ? syntax does not.
We will hopefully introduce a +!images syntax in the future.
Fixes#702.
* allow not to record metrics (response time, etc...)
* this commit doesn't change the UI. If the metrics are disabled
/stats and /stats/errors will return empty response.
in /preferences, the columns response time and reliability will be empty.
The tab icon names are currently hard coded in the templates.
This commit lets us introduce an icon property in the future, e.g:
categories_as_tabs:
general:
icon: search-outline
These dictionaries are no longer part of the general category,
so they're no longer queried by default -> we can enable them
by default without degrading general query performance.
The general category is the category that is searched by default.
From a privacy standpoint it doesn't make sense to send all general
queries to specialized search engines that cannot deal with those
queries anyway.
Previously we didn't have a good place to put search engines that don't
fit into any of the tab categories. This commit automatically puts
search engines that don't belong to any tab category in an "other"
category, that is only displayed in the user preferences (and not above
search results).

Previously all categories were displayed as search engine tabs.

Categories not displayed as tabs can still be searched with !bangs.
Add event listener to query selector::
'#urls img.image'
From the user point of view, I think it is better to hide the image:
img_load_error.svg is helplful in the image category because it still allows to
select the image. IMO, in the news category, the fact there is a missing image
won't help to choose the links. From a developer point of view, the place holder
is signal that may be the engine needs to be updated (at least give a look). The
browser console should show the same information too, but it requires some
additional steps. [1]

Include the source files directly in the `.map` files [1] for two reasons:
1. In the simple theme, modules from `./node_modules` are only available on
developer's build host (a `make node.env` is needed to get the sources). By
example; in the `searxng.min.js.map` file, the `autocomplete.js` is linked at
URL:
../node_modules/autocomplete-js/dist/autocomplete.js
2. Later, when client sources has been moved out of the `./static` URL [2] to
the `<repo-roo>/src` folder, all JS sources are no longer available.
Drawback: `.map` files grow up in size, but this should not bother, because the
files are only loaded in debug mode.

The key of the dictionary 'searx.data.ENGINES_LANGUAGES' is the *engine name*
configured in settings.xml. When multiple engines are configured to use the
same origin engine (e.g. `engine: google`)::
- name: google
engine: google
use_mobile_ui: false
...
- name: google italian
engine: google
use_mobile_ui: false
language: it
...
- name: google mobile ui
engine: google
shortcut: gomui
use_mobile_ui: true
There exists no entry for ENGINES_LANGUAGES[engine.name] (e.g. `name: google
mobile ui` or `name: google italian`). This issue can be solved by recreate the
ENGINES_LANGUAGES::
make data.languages
But this is nothing an SearXNG admin would like to do when just configuring
additional engines, since this just doubles entries in ENGINES_LANGUAGES and
BTW: `make data.languages` has various external requirements which might be not
installed or not available, on a production host.
With this patch, if engine.name fails, ENGINES_LANGUAGES[engine.engine] is used
to get the engine.supported_languages (e.g. `google` for the engine named
`google mobile`).
For an engine, when there is `language: ...` in the YAML settings, the engine
supports only one language, in this case engine.supported_languages should
contains this value defined in settings.yml (e.g. `it` for the engine named
`google italian`).

httpx.RequestError (subclass of httpx.HTTPError) has a property request.
This property raises a RuntimeError if the attributes _request is None.
To avoid a cascade of errors, this commit reads directly the _request attribute.
searx.client.new_client: the proxies parameter is a dictonnary,
and the protocol (key of the dictionnary) is already normalized

the openstreetmap engine imports code from the wikidata engine.
before this commit, specific code make sure to copy the logger variable to the wikidata engine.
with this commit searx.engines.load_engine makes sure the .logger is initialized.
The implementation scans sys.modules for module name starting with searx.engines.
Currently, searx.search.Search calls on_result once the engine results have been merged
(ResultContainer.order_results).
on_result plugins can rewrite the results: once the URL(s) are modified, even they can be merged,
it won't be the case since ResultContainer.order_results has already be called.
This commit call on_result inside for each result of each engines.
In addition the on_result function can return False to remove the result.
Note: the on_result function now run on the engine thread instead of the Flask thread.
close#298
This is a workaround: inside engine code, any call to function in another engine can crash
since the logger won't be initialized except if it is done explicitly.
Instead of raising an exception and therefore hiding all results of the engine.
It make sense to remove that requirement in order to allow the implementation of
search engines that do not always have a description. In fact some search
engines that in 99% of the case have a description like Brave Search or Mojeek
crash completely if they for some reason included a result with no description.
To test this patch try Mojeek:

The engine was added in commit a4b07460 but now it shows new issues [1].
In the 90'th of the last century, dogpile had its own WEB index, but nowadays it
is a meta-search engine [2]
Powered by technology, Dogpile returns all the best results from leading
search engines including Google and Yahoo!
Using dogpile as an engine in SearXNG needs more investigation, a XPath solution
like we have is not enough. It is questionable whether it still makes sense to
investigate more into a meta-search engine with a ReCAPTCHA in front.

Depending on the query not all synonyms are shown because of not the best xpath

This patch disables role 'no-descending-specificity'. IMO it is better to have
this rule active (see below [1]), but it is hard to rewrite the less files to
pass this rule, so for the first I chose to disable this rule.
---
Source order is important in CSS, and when two selectors have the same
specificity, the one that occurs last will take priority. However, the situation
is different when one of the selectors has a higher specificity. In that case,
source order does not matter: the selector with higher specificity will win out
even if it comes first.
The clashes of these two mechanisms for prioritization, source order and
specificity, can cause some confusion when reading stylesheets. If a selector
with higher specificity comes before the selector it overrides, we have to think
harder to understand it, because it violates the source order
expectation. Stylesheets are most legible when overriding selectors always come
after the selectors they override. That way both mechanisms, source order and
specificity, work together nicely.
This rule enforces that practice as best it can, reporting fewer errors than it
should. It cannot catch every actual overriding selector, but it can catch
certain common mistakes.

In the EU there exists a "General Data Protection Regulation" [1] aka GDPR (BTW:
very user friendly!) which requires consent to tracking. To get the consent
from the user, google-news requests are redirected to confirm and get a CONSENT
Cookie from https://consent.google.de/s?continue=...
This patch adds a CONSENT Cookie to the google-news request to avoid
redirection.
The behavior of the CONTENTS cookies over all google engines seems similar but
the pattern is not yet fully clear to me, here are some random samples from my
analysis ..
Using common google search from different domains::
google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816
google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
google.fr: CONSENT=YES+srp.gws-{{date}}-0-RC2.fr+FX+826
When searching about videos (google-videos)::
google.es: CONSENT=YES+srp.gws-{{date}}-0-RC2.es+FX+076
google.de: CONSENT=YES+srp.gws-{{date}}-0-RC2.de+FX+171
Google news has only one domain for all languages::
news.google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816
Using google-scholar search from different domains::
scholar.google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333
scholar.google.fr: does not use such a cookie / did not ask the user
scholar.google.es: does not use such a cookie / did not ask the user
Interim summary:
Pattern is unclear and I won't apply the CONSENT cookie to all google engines.
More experience is need before we generalize the CONSENT cookies over all
google engines.

The query parameters are copied from Whoogle. With the ``all`` language:
- add parameter ``source=lnt``
- don't use parameter ``lr``
- don't add a ``Accept-Language`` HTTP header.
The new signature of function ``get_lang_info()`` is:
lang_info = get_lang_info(params, lang_list, custom_aliases, supported_any_language)
Argument ``supported_any_language`` is True for google.py and False for the other
google engines. With this patch the function now returns:
- query parameters: ``lang_info['params']``
- HTTP headers: ``lang_info['headers']``
- and as before this patch:
- ``lang_info['subdomain']``
- ``lang_info['country']``
