Repair Haskell/Scheme extraction in the new extraction backend design:

Unlike prlist_xxxx and prvect, the function prlist is acting lazily,
which is bad for extraction (synchronization with tables).  We add and
use a prlist_strict function.

Additionaly: 
 - cleanup of the preamble printing
 - no need for 2-pass printing (/dev/null trick) when the language 
   isn't ocaml
