  1. Unhide nightly-only flags. 

    I changed my mind on how these should work. I think it is useful to
"advertise" the existence of these options on stable. The error message
if you try to use it should help guide on what to do.

  3. Add error message for wrong cargo-features placement. 

    This is intended to help if the user puts cargo-features in the
wrong place in Cargo.toml.

  4. Remove publish-lockfile key from manifest. 

    The feature was stabilized without the key in rust-lang#7026 about 1.5 years ago.
(Will follow up with an error message in a subsequent commit.)

  5. Add more helpful message with stabilized -Z flags. 

    Previously, when something was stabilized, Cargo would spit out a very
unhelpful error message about an unknown -Z flag. This changes it so
that it displays a helpful warning (or error).

  6. Rework cargo-features a little. 

    * Add `removed` support.
* Include the version where it is stabilized.
* Include a links to the documentation in the error/warning messages.

  7. Update the internal documentation on unstable features. 

    Attempts to make it clearer on how the different kinds of unstable
support works, and clarify the steps for adding new features
and stabilizing.

  8. Update the user documentation on unstable features.

  9. Add redirects on the unstable docs. 

    This adds some redirects so if there are any links to old documentation,
they will get redirect to new documentation.
