dirstate-item: drop an outdated comments This comment is no longer relevant since we moved away from the `state` internal representation, multiple weeks ago.

dirstate: remove a update_file's special case for `merged` file This case was fishy and can be dealt with by passing more accurate data a higher level. This clarify the API and prepare for a larger rework of the data we feeds to the dirstate.

dirstate: remove a update_file's special case for tracked file with p2 data This case was fishy and can be dealt with by passing more accurate data a higher level. This clarify the API and prepare for a larger rework of the data we feeds to the dirstate.

dirstate: move verification code within the dirstate itself This move implementation details further down the stack and make it the verification code easier to discover. Differential Revision: https://phab.mercurial-scm.org/D11526

dirstate-entry: use `?` for the state of entry without any tracking This is what the dirstate use at a higher level. Differential Revision: https://phab.mercurial-scm.org/D11525

dirstate-item: introduce a `any_tracked` property This property is True is the file is tracked anywhere, either the working copy, or any of the parent. Differential Revision: https://phab.mercurial-scm.org/D11524

dirstate-item: introduce a `maybe_clean` property It is useful for some extension that seek to invalidate some state. Differential Revision: https://phab.mercurial-scm.org/D11523

dirstate: add a `get_entry` method to the dirstate This method give access to the underlying `DirstateEntry` object (or an empty one if None was there). It should allow us to use the more semantic property of the entry instead of the state where we needs it. Differential Revision: https://phab.mercurial-scm.org/D11522

hg-core: silence dead-code warning by adding RevlogEntry::revion() accessor Nightly `rustc` warns about the `RevlogEntry::rev` field not being used. Rather than removing it, I added an accessor since it seems useful to be able to get the entry's revision. Differential Revision: https://phab.mercurial-scm.org/D11548

rust-revset: support explicit `.` revision This is basically the same thing as not specifying a revision, except this is done in the revset resolution function. This allows calls like `rhg cat some-file -r .` to work without falling back. Differential Revision: https://phab.mercurial-scm.org/D11402
