Subject: Adding support for custom entries in notations.

- New command "Declare Custom Entry bar".
- Entries can have levels.
- Printing is done using a notion of coercion between grammar
  entries. This typically corresponds to rules of the form
  'Notation "[ x ]" := x (x custom myconstr).' but also
  'Notation "{ x }" := x (in custom myconstr, x constr).'.
- Rules declaring idents such as 'Notation "x" := x (in custom myconstr, x ident).'
  are natively recognized.
- Rules declaring globals such as 'Notation "x" := x (in custom myconstr, x global).'
  are natively recognized.

Incidentally merging ETConstr and ETConstrAsBinder.

Noticed in passing that parsing binder as custom was not done as in
constr.

Probably some fine-tuning still to do (priority of notations,
interactions between scopes and entries, ...). To be tested live
further.
