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.

BTW this fix an issue in wikipedia: SearXNG's locales zh-TW and zh-HK are now
using language `zh-classical` from wikipedia (and not `zh`).

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).

- fetch_traits(): Fetch languages from peertube's search-index source code.
[mod] Include migration of the request methode from 'supported_languages'
to 'traits' (EngineTraits) object.
[fix] old supported_languages_url is no longer valid since the sources
has been moved to a different path.
- fixed code to pass pylint
- request(): complete re-implementation based on the API docs [1]
- response(): complete re-implementation, adds serveral fields missed before
- add source code documentation

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.
