fd814aac86 [mod] isolation of botdetection from the limiter
This patch was inspired by the discussion around PR-2882 [2].  The goals of this
patch are:

1. Convert plugin searx.plugin.limiter to normal code [1]
2. isolation of botdetection from the limiter [2]
3. searx/{tools => botdetection}/config.py and drop searx.tools
4. in URL /config, 'limiter.enabled' is true only if the limiter is really
   enabled (Redis is available).

This patch moves all the code that belongs to botdetection into namespace
searx.botdetection and code that belongs to limiter is placed in namespace
searx.limiter.

Tthe limiter used to be a plugin at some point botdetection was added, it was
not a plugin.  The modularization of these two components was long overdue.
With the clear modularization, the documentation could then also be organized
according to the architecture.

[2] https://github.com/searxng/searxng/pull/2882#issuecomment-1741716891

To test:

- check the app works without the limiter, check `/config`
- check the app works with the limiter and with the token, check `/config`
- make docs.live .. and read

1ec325adcc [mod] limiter -> botdetection: modularization and documentation
In order to be able to meet the outstanding requirements, the implementation is
modularized and supplemented with documentation.

This patch does not contain functional change, except it fixes issue #2455

----

Aktivate limiter in the settings.yml and simulate a bot request by::

    curl -H 'Accept-Language: de-DE,en-US;q=0.7,en;q=0.3' \
         -H 'Accept: text/html'
         -H 'User-Agent: xyz' \
         -H 'Accept-Encoding: gzip' \
         'http://127.0.0.1:8888/search?q=foo'

In the LOG:

    DEBUG   searx.botdetection.link_token : missing ping for this request: .....

Since ``BURST_MAX_SUSPICIOUS = 2`` you can repeat the query above two time
before you get a "Too Many Requests" response.

d5ecda9930 [mod] move language recognition to get_search_query_from_webapp
To set the language from language recognition and hold the value selected by the
client, the previous implementation creates a copy of the SearchQuery object and
manipulates the SearchQuery object by calling function replace_auto_language().

This patch tries to implement a similar functionality in a more central place,
in function get_search_query_from_webapp() when the SearchQuery object is build
up.

Additional this patch uses the language preferred by the client, if language
recognition does not have a match / the existing implementation does not care
about client preferences and uses 'all' in case of no match.

2ffd446e5c [mod] clarify the difference of the default category and subgrouping
This PR does no functional change it is just an attempt to make more clear in
the code, what a default category is and what a subcategory is.  The previous
name 'others' leads to confusion with the **category 'other'**.

If a engine is not assigned to a category, the default is assigned::

    DEFAULT_CATEGORY = 'other'

If an engine has only one category and this category is shown as tab in the user
interface, this engine has no further subgrouping::

    NO_SUBGROUPING = 'without further subgrouping'

16f0db4493 [mod] replace utils.match_language by locales.match_locale
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``.

c9cd376186 [mod] replace searx.languages by searx.sxng_locales
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).

6e5f22e558 [mod] replace engines_languages.json by engines_traits.json
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*.

3b0f9c07b2 [fix] improve OpenSearch description
Some HTTP-Clients do have issues with the ``opensearch.xml`` from SearXNG
(related [1][2]) while other OpenSearch descriptions[3] (e.g. from qwant) work
flawles.

Inspired by the OpenSearch description from qwant and with informations from the
specification[4] the ``opensearch.xml`` has been *improved*.

- convert `<Url>` methods from lower case to upper case (`POST`|`GET`)
- add `<moz:SearchForm>` and `xmlns:moz="http://www.mozilla.org/2006/browser/search/"`
- add `<Query role="example" searchTerms="SearXNG" />`  [4]

  OpenSearch description documents should include at least one Query element of
  `role="example"` that is expected to return search results. Search clients may
  use this example query to validate that the search engine is working properly.

- modified `<LongName>` to SearXNG
- modified `<Description>` the word 'hackable' scares uninitiated users and was removed
- add the `type="image/png"` to `<Image>`

Test can be done by::

    make run

Visit http://127.0.0.1:8888/ and add the search engine to your WEB-Browser /
test with different WEB-Browser from desktop and Smartphones (are there any iOS
user here, please test on Safari and Chrome).

ad964562ce [fix] move locale code from webapp.py to locales.py and fix #1303
To improve modularization this patch:

- moves *locale* related implementation from the webapp.py application to the
  locale.py module.

- The initialization of the locales is now done in the application (webapp) and
  is no longer done while importing searx.locales.

In the searx.locales module a new dictionary named `LOCALE_BEST_MATCH` has been
added.  In this dictionary we can map languages without a translation to
languages we have a translation for.

To fix #1303 zh-HK has been mapped to zh-Hant-TW (we do not need additional
translations of traditional Chinese)
