Uniformizing generic argument types.
Now, instead of having three unrelated types describing a dynamic
type at each level (raw, glob, top), we have a "('a, 'b, 'c) genarg_type"
whose parameters describe the reified type at each level.
This has various advantages:
- No more code duplication to handle the three level separately;
- Safer code: one is not authorized to mix unrelated types when what
was morally expected was a genarg_type.
- Each level-specialized representation can be accessed through
well-typed projections: rawwit, glbwit and topwit.
Documenting a bit Genarg b.t.w.
