	This patch brings two major changes:
- ``Result.filter_urls(..)`` to pass a filter function for URL fields
- The ``enabled_plugins:`` section in SearXNG's settings do no longer exists.
To understand plugin development compile documentation:
    $ make docs.clean docs.live
and read http://0.0.0.0:8000/dev/plugins/development.html
There is no longer a distinction between built-in and external plugin, all
plugins are registered via the settings in the ``plugins:`` section.
In SearXNG, plugins can be registered via a fully qualified class name.  A
configuration (`PluginCfg`) can be transferred to the plugin, e.g. to activate
it by default / *opt-in* or *opt-out* from user's point of view.
built-in plugins
================
The built-in plugins are all located in the namespace `searx.plugins`.
.. code:: yaml
    plugins:
      searx.plugins.calculator.SXNGPlugin:
        active: true
      searx.plugins.hash_plugin.SXNGPlugin:
        active: true
      searx.plugins.self_info.SXNGPlugin:
        active: true
      searx.plugins.tracker_url_remover.SXNGPlugin:
        active: true
      searx.plugins.unit_converter.SXNGPlugin:
        active: true
      searx.plugins.ahmia_filter.SXNGPlugin:
        active: true
      searx.plugins.hostnames.SXNGPlugin:
        active: true
      searx.plugins.oa_doi_rewrite.SXNGPlugin:
        active: false
      searx.plugins.tor_check.SXNGPlugin:
        active: false
external plugins
================
SearXNG supports *external plugins* / there is no need to install one, SearXNG
runs out of the box.
- Only show green hosted results: https://github.com/return42/tgwf-searx-plugins/
To get a developer installation in a SearXNG developer environment:
.. code:: sh
   $ git clone git@github.com:return42/tgwf-searx-plugins.git
   $ ./manage pyenv.cmd python -m \
         pip install -e tgwf-searx-plugins
To register the plugin in SearXNG add ``only_show_green_results.SXNGPlugin`` to
the ``plugins:``:
.. code:: yaml
    plugins:
      # ...
      only_show_green_results.SXNGPlugin:
        active: false
Result.filter_urls(..)
======================
The ``Result.filter_urls(..)`` can be used to filter and/or modify URL fields.
In the following example, the filter function ``my_url_filter``:
.. code:: python
   def my_url_filter(result, field_name, url_src) -> bool | str:
       if "google" in url_src:
           return False              # remove URL field from result
       if "facebook" in url_src:
           new_url = url_src.replace("facebook", "fb-dummy")
           return new_url            # return modified URL
       return True                   # leave URL in field unchanged
is applied to all URL fields in the :py:obj:`Plugin.on_result` hook:
.. code:: python
   class MyUrlFilter(Plugin):
       ...
       def on_result(self, request, search, result) -> bool:
           result.filter_urls(my_url_filter)
           return True
