This is a tricky area and I need to look at this, but I won't be able to do it very soon, maybe in a week or two.

I need to refresh hygiene details in my memory before reviewing this PR and https://github.com/rust-lang/rust/pull/100387, it will require at least one full working day. I've been very busy the last...

This is no my area of expertise, and also a language change. r? @nikomatsakis @eddyb (because coercions)

I made one more step and separated effective visibilities ("access levels") coming from rustc from similar data collected by rustdoc for extern `DefId`s. The original table is no longer modified...
