Fixed bug #2135 (second-order unification was raising cryptic message)
- made the example work (a call to whd_meta was missing)
- replaced the internal error messages of w_unify_to_subterm_list into
user-understandable messages
- incidentally fixed the meaning of whd_meta (which now takes an evd)
and meta_name (which now does what it means and do not treat differently
the instantiated metas)
