Re-exported symbols (e.g. bar.Foo re-exporting foo.Foo) were not being resolved to their original definitions during safety analysis. This caused check_call to miss unsafe constructors/functions accessed through re-exports, incorrectly marking them as safe. Make the re_exports more visible to the main analysis, and resolve them when needed. I'm not totally happy with this approach, though, because it's would be easy to miss new places that a reexport needs to be chased down. I'll do a bit more thinking, but I'd be interested in architectural suggestions from the team.
Recent fixes
When processing modules in site_packages, track the current package and use that to resolve relative imports. We don't bother doing this for packages in the project because they are currently all collected.
Most of the tests test the shared find_sources code directly, but also add a smoke test each for run-tree and gen-source-db that verify they are both supporting site-packages.
I'm not totally sure if you want this, but it will let me start using run-tree instead of doing a separate gen-source-db + run step. In addition to reducing duplication, this gives run-tree access to site-packages.
