Revision 2860

(get_paras) do not rename *__XS functions anymore

copy their signatures to their perl wrappers so that they got signatures
too (now that we parse the .pm files too) instead of shadowing the perl
function with no signatures

eg:
-sub parse_hdlist() {}
+sub parse_hdlist { my ($_urpm, $_filename, @_more_paras) = @_ }
