it prepares the new architecture change,
everything about multithreading in moved in the searx.search.* packages
previously the call to the "init" function of the engines was done in searx.engines:
* the network was not set (request not sent using the defined proxy)
* it requires to monkey patch the code to avoid HTTP requests during the tests
- add to list of pylint scripts
- add debug log messages
- move API key int `settings.yml`
- improved readability

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, youtube requests are redirected to confirm and get a CONSENT
Cookie from https://consent.youtube.com
This patch adds a CONSENT Cookie to the youtube request to avoid redirection.

Bing has a list of regions that it supports and some of these regions
may have more than one possible language.
In some cases, like Switzerland, these languages are always shown as
options, so there is no issue. But in other cases, like Andorra, Bing
will only show one language at the time, either the region's default or
the request's language if the latter is supported by that region.
For example, if the HTTP request is in French, Andorra will appear as
fr-AD but if the same page is requested in any other language Andorra
will appear as ca-AD.
This is specially a problem when Bing assumes that the request is in
English because it overrides enough language codes to make several major
languages like Arabic dissappear from the languages.py file.
To avoid that issue, I set the Accept-Language header to a language
that's only supported in one region to hopefully avoid these overrides.
At the moment videos without a description are not shown - setting
default content to "" fixes this.
Another current bug is that thumbnails are not displayed. This is caused
by a double slash in the url. For this every trailing slash is now
stripped (for backwards compatibility) and the API response is correctly
parsed.
* searx understand "!ddg !g time" as : send "!g time" to DDG
* !g a DDG bang for Google: DDG return a HTTP redirect to Google
This commit adds a the allows_redirect param not to follow HTTP redirect.
The DDG engine returns a empty result as before without HTTP redirect.
on some queries (like an IT error message), wikipedia returns an HTTP error 400.
this commit returns an empty result instead of showing an error to the user.
Some JSON API returns HTML in either in the HTML or the content.
This commit adds two new parameters to the json_engine:
content_html_to_text and title_html_to_text, False by default.
If True, then the searx.utils.html_to_text removes the HTML tags.
Update crossref, openairedatasets and openairepublications engines
The language_support variable is set to True by default,
and set to False in only 5 engines.
Except the documentation and the /config URL, this variable is not used.
This commit remove the variable definition in the engines, and
set value according to supported_languages length: False when the length is 0,
True otherwise.

By itself recoll does not offer web or API access,
this can be achieved using recoll-webui:
https://framagit.org/medoc92/recollwebui.git
This engine uses a custom 'files' result template
set `base_url` to the location where recoll-webui can be reached
set `dl_prefix` to a location where the file hierarchy as indexed by recoll can be reached
set `search_dir` to the part of the indexed file hierarchy to be searched, use an empty string to search the entire search domain

Disabled by default. Can be enabled by setting the SOCKS proxies to

Requires Tor and updating packages.
To avoid manually adding the timeout on each engine, you can set

time.

A new "base" engine called command is introduced. It is the foundation for all command line engines for now.
You can use this engine to create your own command line engine.
Add some engines (commented out to make sure no one enables anything accidentally):
* git grep: This engine lets you grep in the searx repo.
* locate: If locate is installed and initialized, you can search on the FS.
* find: You can find files with a specific name from where you started searx.
* pattern search in files: This engine utilizes the command fgrep.
* regex search in files: This engine runs `grep` to find a file based on its contents.
and some other exceptions:
* KeyboardInterrupt
* SystemExit
* RuntimeError
* SystemError
* ImportError: an engine with an unmet dependency will stop everything.
A new option is added to engines to hide error messages from users. It
is called `display_error_messages` and by default it is set to `True`.
If it is set to `False` error messages do not show up on the UI.
Keep in mind that engines are still suspended if needed regardless of
this setting.
