phabricator: fix a phabsend crash when processing a renamed binary This was a trivial fix, and some more tests are added to cover binary files. Since the old filecontext is passed in, the old name is still available. But I noticed some weirdness around what it marked as binary and not, and what is viewable in Phabricator. Those things have been flagged, and will probably take some digging. Differential Revision: https://phab.mercurial-scm.org/D8133

test: pin the number of CPU for issue4074 tests On machine with an hundreds of CPUs, the "user" CPU time reported can be inflated by the status steps. Since the test especially focus on the diff computation, we restrict the number of CPU to avoid potential issues. Differential Revision: https://phab.mercurial-scm.org/D8112

rust-dirstatemap: add `NonNormalEntries` class This fix introduces the same encapsulation as the `copymap`. There is no easy way of doing this any better for now. `hg up -r null && time HGRCPATH= HGMODULEPOLICY=rust+c hg up tip` on Mozilla Central, (not super recent, but it doesn't matter): Before: 7:44,08 total After: 1:03,23 total Pretty brutal regression!

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.
