- allow $_o_XXX parameter name which is both unused and optional (same for $_b_XXX)

- shift is a ONE_SCALAR_PARA so that $box->pack_start(shift @l, 0, 0, 4) is parsed correctly
- in arrange_global_vars_declared(), don't keep anything in global_vars_declared, better
  create shadow packages to contain them
- much better merging of multiple files defining functions in the same package.
  This fixes the bad behaviour when using the cache (esp. do_pkgs, but it was even worse
  with things in ugtk2.pm)
