Notation: a new annotation "compat 8.x" extending "only parsing"

 Suppose we declare : Notation foo := bar (compat "8.3").
 Then each time foo is used in a script :

 - By default nothing particular happens (for the moment)

 - But we could get a warning explaining that
   "foo is bar since coq > 8.3".
   For that, either use the command-line option -verb-compat-notations
   or the interactive command "Set Verbose Compat Notations".

 - There is also a strict mode, where foo is forbidden : the previous
   warning is now an error.
   For that, either use the command-line option -no-compat-notations
   or the interactive command "Unset Compat Notations".

 When Coq is launched in compatibility mode (via -compat 8.x),
 using a notation tagged "8.x" will never trigger a warning or error.
