dirstate: move management of nonnormal sets into dirstate map

The dirstate map owns the nonnormal sets, and so should be the class to update
them.  A future implementation of the dirstate will manage these maps
differently.

The action of clearing ambiguous times is now entirely controlled by the
dirstate map, so it moves there too.
