Bump to 1.25.0
* Bump the release version to 1.25
* Bump the bootstrap compiler to the recent beta
* Allow using unstable rustdoc features on beta - this fix has been applied to
the beta branch but needed to go to the master branch as well.
[unix] Don't clone command-line args on startup
Fixes part of #47164 and simplifies the `args` code on non-Apple Unix platforms.
Note: This could change behavior for programs that use both `std::env::args` *and* unsafe code that mutates `argv` directly. However, these programs already behave differently on different platforms. The new behavior on non-Apple platforms is closer to the existing behavior on Apple platforms.
Minor rewrite of env::current_exe docs; clarify symlinks.
- Update example in ‘security’ section to use hard links, like the
linked securityvulns.com example.
- Weaken language on symbolic links – indicate behavior is
platform-specific
Fixes https://github.com/rust-lang/rust/issues/43617.
Correct a few stability attributes
* The extra impls for `ManuallyDrop` were added in #44310 which was only stabilised in 1.22.0.
* The impls for `SliceIndex` were stabilised in #43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable.
* The `From` impls for atomic integers were added in #45610 but most atomic integers are still unstable.
* The `shared_from_slice2` impls were added in #45990 but they won't be stable until 1.24.0.
* The `Mutex` and `RwLock` impls were added in #46082 but won't be stable until 1.24.0.
* Bump the release version to 1.25
* Bump the bootstrap compiler to the recent beta
* Allow using unstable rustdoc features on beta - this fix has been applied to

Redox - Implement rename using new system call
This does the following:
- Update syscall module to match upstream
- Implement rename using new system call
- Make readlink and symlink utilize O_CLOEXEC
- Make readlink and symlink not leave dangling file handles on failure
Implements RFC 1937: `?` in `main`
This is the first part of the RFC 1937 that supports new
`Termination` trait in the rust `main` function.
Thanks @nikomatsakis, @arielb1 and all other people in the gitter channel for all your help!
The support for doctest and `#[test]` is still missing, bu as @nikomatsakis said, smaller pull requests are better :)
Make the output of the column! macro 1 based
Fixes #46868.
I didn't add any regression tests as the change already had to change tests inside the codebase.

[auto-toolstate] Upload the toolstate result to an external git repository, and removes BuildExpectation
This PR consists of 3 commits.
1. (Steps 4–6) The `toolstate.json` output previously collected is now pushed to the https://github.com/rust-lang-nursery/rust-toolstate repository.
2. (Step 7) Revert commit ab018c7, thus removing all traces of `BuildExpectation` and `toolstate.toml`.
3. (Step 8) Adjust CONTRIBUTION.md for the new procedure.
These are the last steps of #45861. After this PR, the toolstate will be automatically computed and published to https://rust-lang-nursery.github.io/rust-toolstate/. There is no need to manage toolstate.toml again.
Closes#45861.
This reverts commit ab018c76e1.
This also adds the `ToolBuild::is_ext_tool` field to replace the previous
`ToolBuild::expectation` field, to indicate whether a build-failure of
certain tool is essential.
Convert warning about `*const _` to a future-compat lint
#46664 was merged before I could convert the soft warning about method lookup on `*const _` into a future-compatibility lint. This PR makes that change.
fixes#46837
tracking issue for the future-compatibility lint: #46906

docs: do not call integer overflows as underflows
In the API docs, integer overflow is sometimes called underflow. Underflow is really when the magnitude of a floating-point number is too small so the number underflows to subnormal or zero. With integers it is always overflow, even if the expected result is less than the minimum number that can be represented.
