Replaces `x_for` functionality with `trusted_proxies`. This allows defining which IP / ranges to trust extracting the client IP address from X-Forwarded-For and X-Real-IP headers. We don't know if the proxy chain will give us the proper client address, so we rely on reading the headers of the proxy before SearXNG (if there is one, in that case it must be added to trusted_proxies) hoping it has done the proper checks. In case a proxy in the chain does not check the client address correctly, integrity is compromised and this should be fixed by whoever manages the proxy, not us. I had to move the get_cnf func to another file (config.py) to prevent cyclic imports since we need to read the list inside _helpers.py Closes https://github.com/searxng/searxng/issues/4907 Closes https://github.com/searxng/searxng/issues/3632 Closes https://github.com/searxng/searxng/issues/3191 Closes https://github.com/searxng/searxng/issues/1237 Related https://github.com/searxng/searxng-docker/issues/386 Related https://github.com/inetol-infrastructure/searxng-container/issues/81
