The consensus on rust-lang/rust-analyzer#12432 seems to be that we are ready for rust-analyzer to ship as a rustup component on the beta and stable channels. This won't always be the preferred distribution method, e.g. the VS Code extension will probably still independently update to its weekly releases, but it's still useful to have a component that follows the release train with the rest of the Rust toolchain. So this removes the nightly-only gating on the bundled component, and removes the "-preview" suffix as well by the usual renaming mechanism.

There's a tarball.is_preview below that needs updating I think.

I don't think so, but cause the actual component remains "*-preview" for the purpose of rustup updates, while the new rename is basically just an alias. We have the same thing still set on all formerly-preview components, even rustfmt.

Ah, interesting. We should consider if there's a way to migrate, feels off that we need to keep what seems like the canonical name the same. Maybe the renames need to be in the other direction or something too?

Maybe so, but we'll need to work with rustup folks to be sure the upgrade path works.

It looks like src/bootstrap/tool.rs needs an update to RustAnalyzer to set stable=true too.

r=me with that done.

Cargo
-----
- [Packages can now inherit settings from the workspace so that
  the settings can be centralized in one place.]
  (rust-lang/cargo#10859) See
  [`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacepackage-table)
  and
  [`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacedependencies-table)
  for more details on how to define these common settings.
- [Cargo commands can now accept multiple `--target` flags to build
  for multiple targets at once]
  (rust-lang/cargo#10766), and the
  [`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)
  config option may now take an array of multiple targets.
- [The `--jobs` argument can now take a negative number to count
  backwards from the max CPUs.]
  (rust-lang/cargo#10844)
- [`cargo add` will now update `Cargo.lock`.]
  (rust-lang/cargo#10902)
- [Added](rust-lang/cargo#10838) the
  [`--crate-type`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-rustc.html#option-cargo-rustc---crate-type)
  flag to `cargo rustc` to override the crate type.
- [Significantly improved the performance fetching git dependencies from GitHub
  when using a hash in the `rev` field.]
  (rust-lang/cargo#10079)

Misc
----
- [The `rust-analyzer` rustup component is now available on the stable channel.]
  (rust-lang/rust#98640)

Compatibility Notes
-------------------
- The minimum required versions for all `-linux-gnu` targets are
  now at least kernel 3.2 and glibc 2.17, for targets that previously
  supported older versions: [Increase the minimum linux-gnu
  versions](rust-lang/rust#95026)
- [Network primitives are now implemented with the ideal Rust
  layout, not the C system layout]
  (rust-lang/rust#78802). This can
  cause problems when transmuting the types.
- [Add assertion that `transmute_copy`'s `U` is not larger than `T`]
  (rust-lang/rust#98839)
- [A soundness bug in `BTreeMap` was fixed]
  (rust-lang/rust#99413) that allowed data
  it was borrowing to be dropped before the container.
- [The Drop behavior of C-like enums cast to ints has changed]
  (rust-lang/rust#96862). These are already
  discouraged by a compiler warning.
- [Relate late-bound closure lifetimes to parent fn in NLL]
  (rust-lang/rust#98835)
- [Errors at const-eval time are now in future incompatibility reports]
  (rust-lang/rust#97743)
- On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements
  were erroneously accepted if they used the high registers (r8 to
  r14) as an input/output operand. [This is no longer accepted]
  (rust-lang/rust#99155).
- [`impl Trait` was accidentally accepted as the associated type
  value of return-position `impl Trait`]
  (rust-lang/rust#97346), without
  fulfilling all the trait bounds of that associated type, as long
  as the hidden type satisfies said bounds. This has been fixed.

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- Windows builds now use profile-guided optimization, providing
  10-20% improvements to compiler performance: [Utilize PGO for
  windows x64 rustc dist builds]
  (rust-lang/rust#96978)
- [Stop keeping metadata in memory before writing it to disk]
  (rust-lang/rust#96544)
- [compiletest: strip debuginfo by default for mode=ui]
  (rust-lang/rust#98140)
- Many improvements to generated code for derives, including
  performance improvements:
  - [Don't use match-destructuring for derived ops on structs.]
    (rust-lang/rust#98446)
  - [Many small deriving cleanups]
    (rust-lang/rust#98741)
  - [More derive output improvements]
    (rust-lang/rust#98758)
  - [Clarify deriving code](rust-lang/rust#98915)
  - [Final derive output improvements]
    (rust-lang/rust#99046)
  - [Stop injecting `#[allow(unused_qualifications)]` in generated
    `derive` implementations](rust-lang/rust#99485)
  - [Improve `derive(Debug)`](rust-lang/rust#98190)
- [Bump to clap 3](rust-lang/rust#98213)
- [fully move dropck to mir](rust-lang/rust#98641)
- [Optimize `Vec::insert` for the case where `index == len`.]
  (rust-lang/rust#98755)
- [Convert rust-analyzer to an in-tree tool]
  (rust-lang/rust#99603)

Pkgsrc changes:
 * This package now contains rust-analyzer, so implicitly
   conflicts with that pkgsrc package.  The same goes for
   the rust-src package.
 * Add NetBSD/arm6 port
 * Add unfinished NetBSD/mipsel port
 * Revert the use of the internal LLVM,
   should now build with the new pkgsrc LLVM (15).
 * Add depndence on compat80 for sparc64 to fix the build
 * Adapt patches
 * Add CHECK_INTERPRETER_SKIP for a few (mostly unused) files.
   (A proper fix may come later.)

  (https://doc.rust-lang.org/stable/std/ffi/type.c_ulonglong.html)
- [`ffi::c_ushort`]
  (https://doc.rust-lang.org/stable/std/ffi/type.c_ushort.html)

These APIs are now usable in const contexts:

- [`slice::from_raw_parts`]
  (https://doc.rust-lang.org/stable/core/slice/fn.from_raw_parts.html)

Cargo
-----
- [Packages can now inherit settings from the workspace so that
  the settings can be centralized in one place.]
  (rust-lang/cargo#10859) See
  [`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacepackage-table)
  and
  [`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacedependencies-table)
  for more details on how to define these common settings.
- [Cargo commands can now accept multiple `--target` flags to build
  for multiple targets at once]
  (rust-lang/cargo#10766), and the
  [`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)
  config option may now take an array of multiple targets.
- [The `--jobs` argument can now take a negative number to count
  backwards from the max CPUs.]
  (rust-lang/cargo#10844)
- [`cargo add` will now update `Cargo.lock`.]
  (rust-lang/cargo#10902)
- [Added](rust-lang/cargo#10838) the
  [`--crate-type`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-rustc.html#option-cargo-rustc---crate-type)
  flag to `cargo rustc` to override the crate type.
- [Significantly improved the performance fetching git dependencies from GitHub
  when using a hash in the `rev` field.]
  (rust-lang/cargo#10079)

Misc
----
- [The `rust-analyzer` rustup component is now available on the stable channel.]
  (rust-lang/rust#98640)

Compatibility Notes
-------------------
- The minimum required versions for all `-linux-gnu` targets are
  now at least kernel 3.2 and glibc 2.17, for targets that previously
  supported older versions: [Increase the minimum linux-gnu
  versions](rust-lang/rust#95026)
- [Network primitives are now implemented with the ideal Rust
  layout, not the C system layout]
  (rust-lang/rust#78802). This can
  cause problems when transmuting the types.
- [Add assertion that `transmute_copy`'s `U` is not larger than `T`]
  (rust-lang/rust#98839)
- [A soundness bug in `BTreeMap` was fixed]
  (rust-lang/rust#99413) that allowed data
  it was borrowing to be dropped before the container.
- [The Drop behavior of C-like enums cast to ints has changed]
  (rust-lang/rust#96862). These are already
  discouraged by a compiler warning.
- [Relate late-bound closure lifetimes to parent fn in NLL]
  (rust-lang/rust#98835)
- [Errors at const-eval time are now in future incompatibility reports]
  (rust-lang/rust#97743)
- On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements
  were erroneously accepted if they used the high registers (r8 to
  r14) as an input/output operand. [This is no longer accepted]
  (rust-lang/rust#99155).
- [`impl Trait` was accidentally accepted as the associated type
  value of return-position `impl Trait`]
  (rust-lang/rust#97346), without
  fulfilling all the trait bounds of that associated type, as long
  as the hidden type satisfies said bounds. This has been fixed.

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- Windows builds now use profile-guided optimization, providing
  10-20% improvements to compiler performance: [Utilize PGO for
  windows x64 rustc dist builds]
  (rust-lang/rust#96978)
- [Stop keeping metadata in memory before writing it to disk]
  (rust-lang/rust#96544)
- [compiletest: strip debuginfo by default for mode=ui]
  (rust-lang/rust#98140)
- Many improvements to generated code for derives, including
  performance improvements:
  - [Don't use match-destructuring for derived ops on structs.]
    (rust-lang/rust#98446)
  - [Many small deriving cleanups]
    (rust-lang/rust#98741)
  - [More derive output improvements]
    (rust-lang/rust#98758)
  - [Clarify deriving code](rust-lang/rust#98915)
  - [Final derive output improvements]
    (rust-lang/rust#99046)
  - [Stop injecting `#[allow(unused_qualifications)]` in generated
    `derive` implementations](rust-lang/rust#99485)
  - [Improve `derive(Debug)`](rust-lang/rust#98190)
- [Bump to clap 3](rust-lang/rust#98213)
- [fully move dropck to mir](rust-lang/rust#98641)
- [Optimize `Vec::insert` for the case where `index == len`.]
  (rust-lang/rust#98755)
- [Convert rust-analyzer to an in-tree tool]
  (rust-lang/rust#99603)
