maintain generic context naming in structure Name_Space (NB: empty = default_naming, init = local_naming);
more explicit Context.generic for Name_Space.declare/define and derivatives (NB: naming changed after Proof_Context.init_global);
prefer Context.pretty in low-level operations of structure Sorts/Type (defer full Syntax.init_pretty until error output);
simplified signatures;
