The method EngineTraits.get_region(..) returns engine's region string
that **best fits** to SearXNG's locale. This means it returns a
region (country) if only a language is set in the locale. By example the method
returns for a locale tag `es` a region `ES`.
Google's search parameter `cr` restricts search results to documents originating
in a particular country / in case of a locale tag (language) as described above,
this argument should be unset in the query send to Google.

It seems that Google is rolling out a modified WEB API [1][2].
In the past there was only the UI language in the `hl` argument but nowadays it
seems a combination of the UI language and the "search region" is mixed in this
argument and the `gl` argument has been removed. I'm very surprised that google
is starting to mix the parameters of the UI with the parameters of the search
index.
This patch modifies the get_google_info(..) function. Beside Google-WEB this
function is also used by other Google services, here are some examples to test
region & language of ..
- Google-WEB: `!go dragon boat :en-CA`
- Google-News: `!gon dragon boat :en-CA`
- Google-Videos: `!gov bmw :en-CA`
- Goolge-Images `!goi bmw :en-CA`

This patch fixes some quirks and issues related to the engines and the network.
Each engine has its own network and this network was broken for the following
engines[1]:
- archlinux
- bing
- dailymotion
- duckduckgo
- google
- peertube
- startpage
- wikipedia
Since the files have been touched anyway, the type annotaions of the engine
modules has also been completed so that error messages from the type checker are
no longer reported.

Partial reverse engineering of the Google engines including a improved language
and region handling based on the engine.traits_v1 data.
When ever possible the implementations of the Google engines try to make use of
the async REST APIs. The get_lang_info() has been generalized to a
get_google_info() function / especially the region handling has been improved by
adding the cr parameter.
searx/data/engine_traits.json
Add data type "traits_v1" generated by the fetch_traits() functions from:
- Google (WEB),
- Google images,
- Google news,
- Google scholar and
- Google videos
and remove data from obsolete data type "supported_languages".
A traits.custom type that maps region codes to *supported_domains* is fetched
from https://www.google.com/supported_domains
searx/autocomplete.py:
Reversed engineered autocomplete from Google WEB. Supports Google's languages and
subdomains. The old API suggestqueries.google.com/complete has been replaced
by the async REST API: https://{subdomain}/complete/search?{args}
searx/engines/google.py
Reverse engineering and extensive testing ..
- fetch_traits(): Fetch languages & regions from Google properties.
- always use the async REST API (formally known as 'use_mobile_ui')
- use *supported_domains* from traits
- improved the result list by fetching './/div[@data-content-feature]'
and parsing the type of the various *content features* --> thumbnails are
added
searx/engines/google_images.py
Reverse engineering and extensive testing ..
- fetch_traits(): Fetch languages & regions from Google properties.
- use *supported_domains* from traits
- if exists, freshness_date is added to the result
- issue 1864: result list has been improved a lot (due to the new cr parameter)
searx/engines/google_news.py
Reverse engineering and extensive testing ..
- fetch_traits(): Fetch languages & regions from Google properties.
*supported_domains* is not needed but a ceid list has been added.
- different region handling compared to Google WEB
- fixed for various languages & regions (due to the new ceid parameter) /
avoid CONSENT page
- Google News do no longer support time range
- result list has been fixed: XPath of pub_date and pub_origin
searx/engines/google_videos.py
- fetch_traits(): Fetch languages & regions from Google properties.
- use *supported_domains* from traits
- add paging support
- implement a async request ('asearch': 'arc' & 'async':
'use_ac:true,_fmt:html')
- simplified code (thanks to '_fmt:html' request)
- issue 1359: fixed xpath of video length data
searx/engines/google_scholar.py
- fetch_traits(): Fetch languages & regions from Google properties.
- use *supported_domains* from traits
- request(): include patents & citations
- response(): fixed CAPTCHA detection (Scholar has its own CATCHA manager)
- hardening XPath to iterate over results
- fixed XPath of pub_type (has been change from gs_ct1 to gs_cgt2 class)
- issue 1769 fixed: new request implementation is no longer incompatible

Does not include migration of the request methode from 'supported_languages'
to 'traits' (EngineTraits) object!

Most engines that support languages (and regions) use the Accept-Language from
the WEB browser to build a response that fits to the language (and region).
- add new engine option: send_accept_language_header

Same behaviour behaviour than Whoogle [1]. Only the google engine with the
"Default language" choice "(all)"" is changed by this patch.
When searching for a locate place, the result are in the expect language,
without missing results [2]:
> When a language is not specified, the language interpretation is left up to
> Google to decide how the search results should be delivered.
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']``
- ``lang_info['language']``

[2] https://github.com/benbusby/whoogle-search/releases/tag/v0.5.4
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.
