I am going to apply 054b865 manually, because the second patch (9010d7e) needs to be discussed. I rushed initially and merged, but then I noticed that the `lib/ims` depends on libxml2, and by moving it into the core kamailio package, that one becomes dependent of libxml2. Am I right? If yes, this needs to be sorted out in a different way (e.g., make a package kamailio-lib-ims)
