This patch replaces the *full of magic* ``utils.match_language`` function by a
``locales.match_locale``. The ``locales.match_locale`` function is based on the
``locales.build_engine_locales`` introduced in 9ae409a0 [1].
In the past SearXNG did only support a search by a language but not in a region.
This has been changed a long time ago and regions have been added to SearXNG
core but not to the engines. The ``utils.match_language`` was the function to
handle the different aspects of language/regions in SearXNG core and the
supported *languages* in the engine. The ``utils.match_language`` did it with
some magic and works good for most use cases but fails in some edge case.
To replace the concurrence of languages and regions in the SearXNG core the
``locales.build_engine_locales`` was introduced in 9ae409a0 [1]. With the last
patches all engines has been migrated to a ``fetch_traits`` and a
language/region concept that is based on ``locales.build_engine_locales``.
To summarize: there is no longer a need for the ``locales.match_language``.

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 The old API suggestqueries.google.com/complete has been replaced
by the async REST API: https://{subdomain}/complete/search?{args}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

searx/data/engine_traits.json
Add data type "traits_v1" generated by the fetch_traits() functions from:
- "duckduckgo" (WEB),
- "duckduckgo images" and
- "duckduckgo weather"
and remove data from obsolete data type "supported_languages".
searx/autocomplete.py:
Reversed engineered Autocomplete from DDG. Supports DDG's languages.
searx/engines/duckduckgo.py:
- fetch_traits(): Fetch languages & regions from DDG.
- get_ddg_lang(): Get DDG's language identifier from SearXNG's locale. DDG
defines its languages by region codes. DDG-Lite does not offer a language
selection to the user, only a region can be selected by the user.
- Cache ``vqd`` value: The vqd value depends on the query string and is needed
for the follow up pages or the images loaded by a XMLHttpRequest (DDG
images). The ``vqd`` value of a search term is stored for 10min in the
redis DB.
- DDG Lite engine: reversed engineered request method with improved Language
and region support and better ``vqd`` handling.
searx/engines/duckduckgo_definitions.py: DDG Instant Answer API
The *instant answers* API does not support languages, or at least we could not
find out how language support should work. It seems that most of the features
are based on English terms.
searx/engines/duckduckgo_images.py: DDG Images
Reversed engineered request method. Improved language and region handling
based on cookies and the enigne.traits_v1 data. Response: add image format to

One reason for the often seen CAPTCHA of the Startpage requests are the
incomplete requests SearXNG sends to startpage.com: this patch is a complete new
implementation of the ``request()`` function, reversed engineered from the
Startpage's search form. The new implementation:
- use traits of data_type: traits_v1 and drop deprecated data_type: supported_languages
- adds time-range support
- adds save-search support
- fix searxng/searxng/issues 1884
- fix searxng/searxng/issues 1081 --> improvements to avoid CAPTCHA
In preparation for more categories (News, Images, Videos ..) from Startpage, the
variable ``startpage_categ`` was set up. The default value is ``web`` and other
categories from Startpage are not yet implemented.

With the language and region tags from the EngineTraitsMap the handling of
SearXNG's tags of languages and regions has been normalized and is no longer
a *mystery*. The "languages" became "locales" that are supported by babel and
by this, the update_engine_traits.py can be simplified a lot.
Other code places can be simplified as well, but these simplifications
should (respectively can) only be done when none of the engines work with the
deprecated EngineTraits.supported_languages interface anymore.
This commit replaces searx.languages by searx.sxng_locales and fix the naming of
some names from "language" to "locale" (e.g. language_codes --> sxng_locales).

Implementations of the *traits* of the engines.
Engine's traits are fetched from the origin engine and stored in a JSON file in
the *data folder*. Most often traits are languages and region codes and their
mapping from SearXNG's representation to the representation in the origin search
engine.
To load traits from the persistence::
searx.enginelib.traits.EngineTraitsMap.from_data()
For new traits new properties can be added to the class::
searx.enginelib.traits.EngineTraits
.. hint::
Implementation is downward compatible to the deprecated *supported_languages
method* from the vintage implementation.
The vintage code is tagged as *deprecated* an can be removed when all engines
has been ported to the *traits method*.

From the analyse of @9Ninety [1] we know that DDG (and may be other engines / I
have startpage in mind) does some kind of TLS fingerprint to block bots.
This patch shuffles the default ciphers from httpx to avoid a cipher profile
that is known to httpx (and blocked by DDG).

When the user choose "Auto-detected", the choice remains on the following queries.
The detected language is displayed.
For example "Auto-detected (en)":
* the next query language is going to be auto detected
* for the current query, the detected language is English.
This replace the autodetect_search_language plugin.
Tineye becomes active as soon as a https:// signature is found in the search
term, but most of the time a reverse image search is not requested when a URL is
specified, often the URL is just from a C&P.
The frequent requests to tineye lead in the end to the SearXNG instance being
blocked by tineye and the user seeing unexpected error messages.
BTW: many maintainers have disabled this engine in their local SearXNG settings.

Adds to the navigation widget, preserving forward/backward nav, and
inserting a list of clickable page numbers between them.
Phone sized devices continue without this widget as deterministic
display under small screen sizes has not been solved.
The widget is agnostic to the actual amount of pages there are that one
can navigate to and as such shows all plausible, albeit not necessarilly
valid, possibilities.
This widget does not interfere with infinite scroll in any fashion.

This patch is to hardening the parsing of the bing response:
1. To fix [2087] check if the selected result item contains a link, otherwise
skip result item and continue in the result loop. Increment the result
pointer when a result has been added / the enumerate that counts for skipped
items is no longer valid when result items are skipped.
To test the bugfix use: ``!bi :all cerbot``
2. Limit the XPath selection of result items to direct children nodes (list
items ``li``) of the ordered list (``ol``).
To test the selector use: ``!bi :en pontiac aztek wiki``
.. in the result list you should find the wikipedia entry on top,
compare [2068]
[2087] https://github.com/searxng/searxng/issues/2087
[2068] https://github.com/searxng/searxng/issues/2068
This changes the Suggestions to be a single column, not a wrapping row,
changing the input to be incapable of overflowing into visually adjacent
elements.
Modify the XPath selector to get the wikipedia result plus small fixes.
About result content: especially with the Wikipedia result, we'd get several
paragraph elements, only the first paragraph would be taken and displayed on the
search result

Default behavior of urllib.parse_qs is to discard blank values, causing a preference of none to be deserialized as undefined, using the instance default rather than the selected preference.
redis.Redis.from_url(url) doesn't check if the url is valid
Before this commit: actual error are detected later when the client is actually used.
With this commit, client() makes sure to return a valid Redis client or None.
Also, the code makes sure not to log the password of the Redis URL
settings.yml:
* The default URL was unix:///usr/local/searxng-redis/run/redis.sock?db=0
* The default URL is now "false"
The default URL makes the log difficult to deal with:
if the admin didn't install a Redis instance, the logs record a false error.
It worked before because SearXNG initialized the Redis connection when the limiter started.
In this commit, SearXNG initializes Redis in searx/webapp.py
so various components can use Redis without taking care of the initialization step.

Previously raise_for_httperror were ignoring all HTTP error,
which make defective engines invisible in the stats.
With the POST method, autocomplete.js does not URL encode the values.
