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).

In my tests I see bots rotating IPs (with endless IP lists). If such a bot has
100 IPs and has three attempts (SUSPICIOUS_IP_MAX = 3) then it can successfully
send up to 300 requests in one day while rotating the IP. To block the bots for
a longer period of time the SUSPICIOUS_IP_WINDOW, as the time period in which an
IP is observed, must be increased.
For normal WEB-browsers this is no problem, because the SUSPICIOUS_IP_WINDOW is
deleted as soon as the CSS with the token is loaded.
SUSPICIOUS_IP_WINDOW = 3600 * 24 * 30
Time (sec) before sliding window for one suspicious IP expires.
SUSPICIOUS_IP_MAX = 3
Maximum requests from one suspicious IP in the :py:obj:`SUSPICIOUS_IP_WINDOW`."""

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.

- counting requests in LONG_WINDOW and BURST_WINDOW is not needed when the
request is validated by the link_token method [1]
- renew a ping-key on validation [2], this is needed for infinite scrolling,
where no new token (CSS) is loaded. / this does not fix the BURST_MAX issue in
the vanilla limiter
- normalize the counter names of the ip_limit method to 'ip_limit.*'
- just integrate the ip_limit method straight forward in the limiter plugin /
non intermediate code --> ip_limit now returns None or a werkzeug.Response
object that can be passed by the plugin to the flask application / non
intermediate code that returns a tuple

To intercept bots that get their IPs from a range of IPs, there is a
``SUSPICIOUS_IP_WINDOW``. In this window the suspicious IPs are stored for a
longer time. IPs stored in this sliding window have a maximum of
``SUSPICIOUS_IP_MAX`` accesses before they are blocked. As soon as the IP makes
a request that is not suspicious, the sliding window for this IP is droped.

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

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.

If there were no results but errors in the engines then the error dialogs of the
engines was displayed in the result list.
With the new design errors of the engines should only be displayed in the
sidebar and at the same time duplications of the (template) code will be
avoided.

* set border top and bottom on sidebar collasables
* inrease peading on summary so its easier to click on mobile
* remove margins and add flex wrapper to normalize elements in sidebar
Make elements in the sidebar collapse able. Except infoboxes all elements in
the sidebar are collapsed by default.
By folding out the sidebar elements, the UI looks less cluttered. Especially on
small devices like smartphones, where the sidebar is above the results list, the
UX should be improved [1].
