rust-dirstatemap: cache non normal and other parent set
Performance of `hg update` was significantly worse since the introduction of
the Rust `dirstatemap`. This regression was noticed by Valentin Gatien-Baron
when working on a large repository, as it goes unnoticed for smaller
repositories like Mercurial itself.
This fix introduces the same getter/setter mechanism at `hg-core` level as
for `set/get_dirs`.
While this technique is, as previously discussed, quite suboptimal, it fixes an
important enough problem. Refactoring `hg-core` to use the typestate
pattern could be a good approach to improving code quality in a future patch.
This is a graft of stable of 83b2b829c94e
