733b795d53 [fix] make flask_babel.gettext() work in engine modules (L10n & threads)
incident:
  flask_babel.gettext() does not work in the engine modules.

cause:
  the request() and response() functions of the engine modules run in the
  processor, whose search() method runs in a thread and in the threads the
  context of the Flask app does not exist. The context of the Flask app is
  needed by the gettext() function for the L10n.

Solution:
  copy context of the Flask app into the threads. [1]

special case:
  We cannot equip the search() method of the processors with the decorator [1],
  because the decorator requires a context (Flask app) that does not yet exist
  at the time of the initialization of the processors (the initialization of the
  processors is part of the initialization of the Flask app).

fa1ef9a07b [mod] move some code from webapp module to webutils module (no functional change)
Over the years the webapp module became more and more a mess.  To improve the
modulaization a little this patch moves some implementations from the webapp
module to webutils module.

Merge pull request #2357 / limiter -> botdetection
The monolithic implementation of the limiter was divided into methods and
implemented in the Python package searx.botdetection.  Detailed documentation on
the methods has been added.

The methods are divided into two groups:

1. Probe HTTP headers

- Method http_accept
- Method http_accept_encoding
- Method http_accept_language
- Method http_connection
- Method http_user_agent

2. Rate limit:

- Method ip_limit
- Method link_token (new)

The (reduced) implementation of the limiter is now in the module
searx.botdetection.limiter.  The first group was transferred unchanged to this
module.  The ip_limit contains the sliding windows implemented by the limiter so
far.

This merge also fixes some long outstandig issue:

- limiter does not evaluate the Accept-Language correct [1]
- limiter needs a IPv6 prefix to block networks instead of IPs [2]

Without additional configuration the limiter works as before (apart from the
bugfixes).  For the commissioning of additional methods (link_toke), a
configuration must be made in an additional configuration file.  Without this
configuration, the limiter runs as before (zero configuration).

The ip_limit Method implements the sliding windows of the vanilla limiter,
additionally the link_token method can be used in this method.  The link_token
method can be used to investigate whether a request is suspicious. To activate
the link_token method in the ip_limit method add the following to your
/etc/searxng/limiter.toml::

    [botdetection.ip_limit]
    link_token = true

2149e88bdd [mod] template preferences: split into elements (no functional change)
HINT: this patch has no functional change / it is the preparation for following
      changes and bugfixes

Over the years, the preferences template became an unmanageable beast.  To make
the source code more readable the monolith is splitted into elements.  The
splitting into elements also has the advantage that a new template can make use
of them.

The reversed checkbox is a quirk that is only used in the prefereces and must be
eliminated in the long term.  For this the macro 'checkbox_onoff_reversed' was
added to the preferences.html template.  The 'checkbox' macro is also a quirk of
the preferences.html we don't want to use in other templates (it is an
input-checkbox in a HTML form that was misused for status display).

38431d2e14 [fix] correct determination of the IP for the request
For correct determination of the IP to the request the function
botdetection.get_real_ip() is implemented.  This fonction is used in the
ip_limit and link_token method of the botdetection and it is used in the
self_info plugin.

A documentation about the X-Forwarded-For header has been added.

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``.

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)

3bb62823ec [fix] dailymotion engine: filter by language & country
- fix the issue of fetching more the 7000 *languages*
- improve the request function and filter by language & country
- implement time_range_support & safesearch
- add more fields to the response from dailymotion (allow_embed, length)
- better clean up of HTML tags in the 'content' field.

This is more or less a complete rework based on the '/videos' API from [1].
This patch cleans up the language list in SearXNG that has been polluted by the
ISO-639-3 2 and 3 letter codes from dailymotion languages which have never been
used.

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.
