[DRAFT] Fixes for NGINX nginx 1.23.0

As of nginx 1.23 the cache control headers are re-implemented as al linked list.
This reworks our code that manipulates this header to work with that.

Still a draft: this change probably needs to be conditioned against nginx version
with ifdefs, so older version can still be built as well. Hence, still a draft.

+# What is pagespeed?
+
+The PageSpeed Modules, [mod_pagespeed](https://github.com/apache/incubator-pagespeed-mod) and [ngx_pagespeed](https://github.com/apache/incubator-pagespeed-ngx), are open-source webserver modules that [optimize your site automatically](https://www.modpagespeed.com/doc/filters).
+
+ngx_pagespeed speeds up your site and reduces page load time by automatically
+applying web performance best practices to pages and associated assets (CSS,
+JavaScript, images) without requiring you to modify your existing content or
+workflow. Features include:
+
+- Image optimization: stripping meta-data, dynamic resizing, recompression
+- CSS & JavaScript minification, concatenation, inlining, and outlining
+- Small resource inlining
+- Deferring image and JavaScript loading
+- HTML rewriting
+- Cache lifetime extension
+- and [more](https://developers.google.com/speed/docs/mod_pagespeed/config_filters)
+
+To see ngx_pagespeed in action, with example pages for each of the
+optimizations, see our [demonstration site](http://ngxpagespeed.com).

+# What is nginx?
+
+Nginx (pronounced "engine-x") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server). The nginx project started with a strong focus on high concurrency, high performance and low memory usage.
+> [wikipedia.org/wiki/Nginx](https://en.wikipedia.org/wiki/Nginx)
+
+# What is nginx-pagespeed?
+
+The nginx-pagespeed brings all the goods of nginx and pagespeed together in one single small alpine docker image. Nginx-pagespeed aims to be 100% compatible with the plain [nginx](https://hub.docker.com/_/nginx/) images. Meaning, nginx-pagespeed can be a safe drop-in replacement for any container running `nginx:alpine`.
+
+Nginx-pagespeed makes it easy to start optimizing your website by reducing page load time, without requiring you to modify existing content.
+
+# How to use this image
+
+## Hosting some simple static content
+
+```console
+$ docker run --name pagespeed-nginx -v /some/content:/usr/share/nginx/html:ro -d pagespeed/nginx-pagespeed
+```
+
+Alternatively, a simple `Dockerfile` can be used to generate a new image that includes the necessary content (which is a much cleaner solution than the bind mount above):
+
+```dockerfile
+FROM pagespeed/nginx-pagespeed
+COPY static-html-directory /usr/share/nginx/html
+```
+
+Place this file in the same directory as your directory of content ("static-html-directory"), run `docker build -t some-content-ngxpagespeed .`, then start your container:
+
+```console
+$ docker run --name my-nginx-pagespeed -d some-content-ngxpagespeed
+```
+
+## Exposing external port
+
+```console
+$ docker run --name my-nginx-pagespeed -d -p 8080:80 some-content-ngxpagespeed
+```
+
+Then you can hit `http://localhost:8080` or `http://host-ip:8080` in your browser.
+
+## Complex configuration
+
+```console
+$ docker run --name my-custom-nginx-pagespeed -v /host/path/nginx.conf:/etc/nginx/nginx.conf:ro -d pagespeed/nginx-pagespeed
+```
+
+For information on the syntax of the nginx configuration files, see [the official documentation](http://nginx.org/en/docs/) (specifically the [Beginner's Guide](http://nginx.org/en/docs/beginners_guide.html#conf_structure)). For pagespeed specific nginx config syntax, see [Beginner's guide](https://www.modpagespeed.com/doc/configuration) or a complete overview of [all pagespeed filters](https://www.ngxpagespeed.com/).
+For a quick start on pagespeed specific configuration see []
+
+If you wish to adapt the default configuration, use something like the following to copy it from a running nginx-pagespeed container:
+
+```console
+$ docker run --name tmp-ngxpagespeed-container -d pagespeed/nginx-pagespeed
+$ docker cp tmp-ngxpagespeed-container:/etc/nginx/nginx.conf /host/path/nginx.conf
+$ docker rm -f tmp-ngxpagespeed-container
+```
+
+This can also be accomplished more cleanly using a simple `Dockerfile` (in `/host/path/`):
+
+```dockerfile
+FROM pagespeed/nginx-pagespeed
+COPY nginx.conf /etc/nginx/nginx.conf
+```
+
+If you add a custom `CMD` in the Dockerfile, be sure to include `-g daemon off;` in the `CMD` in order for nginx to stay in the foreground, so that Docker can track the process properly (otherwise your container will stop immediately after starting)!
+
+Then build the image with `docker build -t custom-ngxpagespeed .` and run it as follows:
+
+```console
+$ docker run --name my-custom-ngxpagespeed-container -d custom-ngxpagespeed
+```
+
+### Using environment variables in nginx configuration
+
+Out-of-the-box, nginx doesn't support environment variables inside most configuration blocks. But `envsubst` may be used as a workaround if you need to generate your nginx configuration dynamically before nginx starts.
+
+Here is an example using docker-compose.yml:
+
+```yaml
+web:
+  image: pagespeed/nginx-pagespeed
+  volumes:
+   - ./mysite.template:/etc/nginx/conf.d/mysite.template
+  ports:
+   - "8080:80"
+  environment:
+   - NGINX_HOST=foobar.com
+   - NGINX_PORT=80
+  command: /bin/bash -c "envsubst < /etc/nginx/conf.d/mysite.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"
+```
+
+The `mysite.template` file may then contain variable references like this:
+
+`listen       ${NGINX_PORT};
+`
+
+# Image Variants
+
+The `pagespeed/nginx-pagespeed` images come in many flavors, each designed for a specific use case.
+
+## `pagespeed/nginx-pagespeed:<version>`
+
+This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
+
+## `nginx:edge`
+
+This image has the most up-to-date system packages available in the [Alpine Linux project](http://alpinelinux.org). This means the latest LibreSSL and musl-libc, with the downside of having less tested system packages.
+
+
+## Using the Dockerfile
+### Use docker build command to build an image from dockerfile:
+  docker build -t <image_tag>  <dockerfile_path> .
+    $ docker build -t ngxpagespeed-alpine38-ngxstable stable/3.8/nginx-stable
+  Refer [this](https://docs.docker.com/engine/reference/commandline/build/) for additional options.
+
+### Run this container as an independent service:
+    $ docker run -d -p 80:80 <image_tag>
+  Refer [this](https://docs.docker.com/engine/reference/run/) for additional options.
+
+## Requirements for building:
+- > 3 GB of free diskspace
+- 2GB of memory
+- an x86_64 compatible processor
+- Docker CE > 17.3.2

+# Disclaimer
+Apache PageSpeed is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
