This commit stabilizes the std::time module and the Duration type.
Duration::span remains unstable, and the Display implementation for
Duration has been removed as it is still being reworked and all trait
implementations for stable types are de facto stable.

This is a [breaking-change] to those using Duration's Display
implementation.

I'm opening this PR as a platform for discussion - there may be some method renaming to do as part of the stabilization process.

I'm happy with this course of action. Could you also tag the trait implementations with the same stability tag as well?

I'm likewise fine with this general direction, modulo the renamings discussion on the internals thread. Will try to weigh in there soon.

I also think it's time to get this done, and don't have opinions about the fine details - seems like this type has been well-polished at this point.

I'd definitely like to hear @lifthrasiir's opinions about this since rust-chrono depends on it.

I have no particular objection, as Chrono has been a (relatively) happy user of the in-tree Duration type. I would have to adjust Chrono to deal with the removal of Display implementation but I can deal with it.

I've updated the PR to rename secs to as_secs and extra_nanos to subsec_nanos in response to feedback from the internals discussion.

☔ The latest upstream changes (presumably #27393) made this pull request unmergeable. Please resolve the merge conflicts.

Can you keep deprecated versions of the old method names? We do this even for unstable APIs to ease changes in.

Otherwise, I'm ready to r+ assuming everyone is on board backporting this stabilization to 1.3 (which has essentially no downside, AFAICT.)

(which has essentially no downside, AFAICT.)

The downside is a deviation from our standard release process. Yes, it's a bit painful to just miss a train, but at the same time, I don't want us to get in the habit of it.

I'm assuming I should leave the old versions unstable and then cut them out in a release or two?

Should I change the feature for the stable functionality? Tidy's complaining:

error: feature 'duration' is both stable and unstable

@alexcrichton

Yeah it's fine to just change the feature name of the deprecated methods to something new like duration_old.

FYI: we're going to discuss the backporting question in the core team meeting today.

Cool. Adjusted the feature for the old methods.

We discussed this at the core team meeting and the consensus is that it's fine to backport this stabilization to 1.3 beta. In the future, we hope to avoid this by having more explicit "go/no go" subteam meetings around stabilization, sufficiently prior to the beta being cut.

Turn nonzeroing move hints back off by default.

This is a temporary workaround for the bugs that have been found in
the implementation of PR rust-lang#26173.

 * pnkfelix is unavailable in the short-term (i.e. for the next week) to fix them.

 * When the bugs are fixed, we will turn this back on by default.

(If you want to play with the known-to-be-buggy optimization in the
meantime, you can opt-back in via the debugging option that this
commit is toggling.)
