revlog: deal with nodemap deletion within the index
Since the nodemap data now live in the index, it should be the index
responsibility to ensure the data are up to date.
The C version of the index is already dealing with such deletion.
This work is part of a refactoring to unify the revlog index and the nodemap.
This unification prepare the use of a persistent nodemap.
