Generalized the possibility to refer to a global name by a notation

string in most commands expecting a global name (e.g. 'Print "+"' for
an infix notation or 'Print "{ _ } + { _ }"' for a misfix notation,
possibly surrounded by a scope delimiter). Support for such smart
globals in VERNAC EXTEND to do.

Added a file smartlocate.ml for high-level globalization functions.

Mini-nettoyage metasyntax.ml.
