Extended interface mangler with deprecations handling.

NOTE: Whoever wrote this part of the driver without adding a HUGE
warning in MkIface.lhs to keep both files in synch deserves the most
severe punishment imaginable (huge stick, etc.)!  >:-(  The seemingly
magical random rearrangement of the interface file outside Haskell's
realm can drive you mad if you forget this...
