Move JLLs to own folder

[oxinabox]

This implements @KristofferC 's idea from #78672 (comment)
and should (for now at least) close #78672

the script i used to do this is:

using Pkg: @pkg_str
pkg"activate --temp"
pkg"add Glob@1.3"

using Glob

mkpath.(joinpath.("jll", string.('A':'Z')))
paths = glob(glob"*/*_jll/") 
mv.(paths, joinpath.("jll", paths))

reg_file = read("Registry.toml", String)
new_reg_file = replace(reg_file, 
    r"path = \"(.*_jll)\""=> s"path = \"jll/\1\""
)
write("Registry.toml", new_reg_file)


run(`git add jll`)
run(`git commit -m "Move JLLs to own folder" -a`)
run(`git push --force-with-lease`)

Nice, we'll have to ensure Registrator doesn't freak out by this (and it should also be updated to register new jlls in this subdir) but I think this is a good idea.

[staticfloat]

Sounds good to me!

Nice, we'll have to ensure Registrator doesn't freak out by this (and it should also be updated to register new jlls in this subdir) but I think this is a good idea.

IIRC, Ygg uses RegistryTools to create the registration PRs (not Registrator), so we'd need to apply the changes there.

[DilumAluthge]

SGTM!

Let's make the necessary changes to RegistryTools before we merge this PR?

[oxinabox]

Can we merge this, or do we need to rebuild a manifest on some Yggdrasil bot?

[DilumAluthge]

I think we need JuliaPackaging/BinaryBuilder.jl#1267

[oxinabox]

that was merged and then reverted.

Meanwhile this PR has gained conflicts.
I will again reset it to master then rerun the script to make the changes and force push back here. Easy enough

AutoMerge will be unhappy about new jll registrations unless RegistryCI is updated with the new RegistryTools version. But that's not compatible with Julia < 1.6 so JuliaRegistries/RegistryTools.jl#85 might need to be backported to a new RegistryTools 1.x release as well.

[DilumAluthge]

I've released a new RegistryTools 2.2 that restores compatibility with Julia 1.1+.

We need to merge JuliaRegistries/RegistryCI.jl#500 and register RegistryCI 8.3.

Then we need to update the CI manifest in the General registry to use RegistryCI 8.3.

[oxinabox]

So current blocker is yggdrasil to the new registry tools?
Is anyone working on that?

[DilumAluthge]

JuliaPackaging/BinaryBuilder.jl#1269

Someone need to review and merge that PR.

[oxinabox]

OK, I believe there should no longer be any blockers.
Is that correct?
and I have rebased, shall we merge this?

[DilumAluthge]

SGTM. Can you run the script again? And then we can quickly merge before more conflicts arise.
