More formal analysis of the header dep fails:

7 fails for iostream.h
1 fail for fstream.h

The rest of these pre-iso.h removals have no impact. I see

vector.h
stream.h
hash_map.h

Already being dealt with at the (auto) conf level (although usage of
these is minor, at one each).

I'll work on fixing up the above 8 errors.

I see the libsigc++ and boost fallout for the name lookup changes as
impacting a lot of packages filed as header dep: I'll work on fixing
these two up first and then the rest of the issues will become much
easier to see.
