dirstatemap: conclude `reset_state` with logic using the new __init__ Now the DirstateItem can deal with most of the logic related to its initialization, our goal is to migrate the function to a more "unified" way were minimal processing is done early before more generic code gets into play. Nobody is calling this code yet, but this is about to change. Differential Revision: https://phab.mercurial-scm.org/D11322
