I've rewritten the importer because the previous one missed out symbols that were defined but weren't part of calls; this caused the database to think some internal symbols were actually external. This hasn't actually been fixed; you can still see external packages listed with no call lines going to them, but the new importer is in my opinion better written and simplifies the import process.
If this is OK for master then I'll update the import documentation and remove the original callgraph-parser.py.
