rustdoc: Improve impl disambiguation

* Don't disambiguate if there are multiple impls for the same type.
* Disambiguate for impls of &Foo and &mut Foo.
* Don't try to disambiguate generic types.

29dece1c8b Auto merge of #39523 - alexcrichton:fpic, r=aturon 
Pass -fPIC to native compiles on 32-bit

This is apparently a regression from 1.14.0 to 1.15.0. Previously we
passed `-fPIC` to C compilers on i686 targets, but the `gcc` crate
apparently [explicitly] didn't do this. I don't recall why that was
avoided but it was [previously passed by the makefiles][mk] and this
seems to have [caused a regression][regression] in Firefox, so this
commit reverts back to passing `-fPIC`.

[explicitly]: https://github.com/alexcrichton/gcc-rs/commit/362bdf20

96bf9ba94d Rollup merge of #39512 - oconnor663:try_wait, r=alexcrichton 
make Child::try_wait return io::Result<Option<ExitStatus>>

This is much nicer for callers who want to short-circuit real I/O errors
with `?`, because they can write this

    if let Some(status) = foo.try_wait()? {
        ...
    } else {
        ...
    }

instead of this

    match foo.try_wait() {
        Ok(status) => {
            ...
        }
        Err(err) if err.kind() == io::ErrorKind::WouldBlock => {
            ...
        }
        Err(err) => return Err(err),
    }

The original design of `try_wait` was patterned after the `Read` and
`Write` traits, which support both blocking and non-blocking
implementations in a single API. But since `try_wait` is never blocking,
it makes sense to optimize for the non-blocking case.

Change deprecation warning to indicate custom derive support was removed

I'm very new to Rust and the message was confusing to me (using nightly and not really sure if I was > 1.15 or not).

Fix short hand struct doc

Don't want to discredit @hngiang effort on this issue.

I just want to lend a hand to fix this issue #38830, it is a very nice feature and is seemingly completed.

Fixes #39096

Delete the makefile build system

This PR deletes the makefile build system in favor of the rustbuild build system. The beta has now been branched so 1.16 will continue to be buildable from the makefiles, but going forward 1.17 will only be buildable with rustbuild.

Rustbuild has been the default build system [since 1.15.0](https://github.com/rust-lang/rust/pull/37817) and the makefiles were [proposed for deletion](https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368) at this time back in November of last year.

And now with the deletion of these makefiles we can start getting those sweet sweet improvements of using crates.io crates in the compiler!

Add support for test suites emulated in QEMU

This commit adds support to the build system to execute test suites that cannot
run natively but can instead run inside of a QEMU emulator. A proof-of-concept
builder was added for the `arm-unknown-linux-gnueabihf` target to show off how
this might work.

In general the architecture is to have a server running inside of the emulator
which a local client connects to. The protocol between the server/client
supports compiling tests on the host and running them on the target inside the
emulator.

Closes #33114

A few ergonomic From impls for SocketAddr/IpAddr

My main motivation is removing things like this: `"127.0.0.1:3000".parse().unwrap()`. Instead, this now works: `SocketAddr::from(([127, 0, 0, 1], 3000))` or even `([127, 0, 0, 1], 3000).into())` when passing to a function.

Improve error message for uninferrable types #38812

Hello,

I tried to improve the error message for uninferrable types. The error code is `E0282`.

```rust

error[E0282]: type annotations needed
 --> /home/cengizIO/issue38812.rs:2:11
  |
2 |   let x = vec![];
  |       -   ^^^^^^ cannot infer type for `T`
  |       |
  |       consider giving `x` a type
  |
  = note: this error originates in a macro outside of the current crate
```

and

```rust

error[E0282]: type annotations needed
 --> /home/cengizIO/issue38812.rs:2:15
  |
2 |   let (x,) = (vec![],);
  |       ----    ^^^^^^ cannot infer type for `T`
  |       |
  |       consider giving a type to pattern
  |
  = note: this error originates in a macro outside of the current crate
```

Rust compiler now tries to find uninferred `local`s with type `_` and adds them into the error message.

I'm probably wrong on wording that I used. Please feel free to suggest better alternatives.

Thanks @nikomatsakis for mentoring 🍺

Any comments/feedback is more than welcome!

Thank you

e53eaa385e Rename manifest_version to manifest-version 
The current manifests encode this with a dash in the name, so we should preserve
that!

c14f87e3b0 Auto merge of #39324 - clarcharr:ipv6_u128, r=alexcrichton 
Ipv6Addr <-> u128

Because we have `u128` now, it makes sense to add a conversion between `Ipv6Addr` and `u128` in addition to the existing one between `Ipv4Addr` and `u32`.

This shouldn't violate the existing feature gate on `u128` because you can't use the type without the feature gate, but if i have to add something, I can.
