The `url_normalize` function is used to validate and normalize URLs. As such, it does not allow for some special characters to be part of the URLs that are to be normalized. As we want to allow using globs in some configuration keys making use of URLs, namely `http.<url>.<key>`, but still normalize them, we need to somehow enable some additional allowed characters.
To do this without having to change all callers of `url_normalize`, where most do not actually want globbing at all, we split off another function `url_normalize_1`. This function accepts an additional parameter `allow_globs`, which is subsequently called by `url_normalize` with `allow_globs=0`.
As of now, this function is not used with globbing enabled. A caller will be added in the following commit.
