Kill off some dodgy JS callbacks

None of these are currently reachable because the IsSafeMode
method always returns true.  This, in turn, will let us kill
off some file (as in fopen()) based parsing. That, in turn,
will let us kill of some more now-unreachable code.

In general, we don't want to have unsafe modes.
