Deploy InfoPath 2010 list form with query filter

What is this about? Well, I needed a custom SharePoint list, with a customized InfoPath form for it, and this form had to read one parameter from the URL. Nothing complicated at all, there are many posts on how to customize forms for SharePoint lists and how to pass an URL parameter for this form. But in my case I needed it all deployable with a package and this puts another level of complexity. Therefore I decided to wrap the procedure in the post below - to make sure that I don’t forget it after a while.
