Subject: preprocesser function now only returns a pp_err_t

We leave the parameter tokens alone, considering it constant, while
the parameter vec_out is used to hold the new stream of tokens.  This
allows the caller to have a before and after view on the token stream
and reduces the worry of double frees.
