[Secure-testing-team] Let's get rid of all pre-2003 TODOs

[Moritz Muehlenhoff]

Can someone please apply some sed magic and rewrite all open TODOs
as "NOT-FOR-US: Data pre-dating the Security Tracker"? Nearly 5000
open TODOs keep attention away from the real issues that need
evaluation.

Cheers,
        Moritz
