Tentative patch

Removed the npeel function argument, also removed body_cost_vec and the
corresponding release ()es.  I'm not so sure about the semantics of vecs in
general.  Are we leaking memory when not releasing the body_cost_vecs contained
in the various _vect_peel_extended_infos?  If it was RAII-like body_cost_vec
there would have been no need to release () body_cost_vec before, so I assume
it is not.
