Helper to file stablereqs?

[thesamesam]

We are nearly there wrt the stablereq/archtesting toolset, but not quite:

• Testing packages: app-portage/pkg-testing-tools or app-portage/tatt
• Getting list of work from Bugzilla, updating Bugzilla: app-portage/nattka
• Processing said work automatically: https://github.com/arthurzam/tattoo
• Finding stablereqs to file (or kwreqs): pkgcheck scan -k StableRequest or pkgcheck scan -k DroppedKeywords

But we have nothing to help file stablereqs. slyfox pointed this out a while ago at https://trofi.github.io/posts/214-filing-STABLEREQ-for-lazies.html (https://bugs.gentoo.org/708912). I think this would be a good fit for pkgdev.

So, funny enough, I was planing working on it this weekend. While I'm unsure about the name (I was thinking about pkgdev bugs - bad name, right...), I did have a plan for it:

• accepts list of atoms (=cat/pkg-ver)
• finds all extra missing packages (similar to nattka make-package-list)
• build a directed graph - based on hard dependency (AKA blocks field in bug)
• all packages that are in circular dependency in this graph would be collected into one "super node" (which translates into one bug with multiple packages in package list)
• enable the user to stop and get the .dot file showing the graph
• finally, for each new node, create automatically the bug, dependencies, maintainers
• have a flag to automatically add CC-ARCHES keyword.
