This pulls in https://github.com/rust-lang/cargo/pull/7159, which
ensures that documenting proc macros works correctly.

Last two commits bumped rustc-ap-* crates which also transitively
updated rustc_data_structures. That crate enables the "nightly"
whereas Cargo's dep does not hence why we need to unify the features
to deduplicate the artifacts.
|
|
Cargo's syn now has the `full` feature, so add it here to keep it in sync.
|
|
Currently `rustfmt` is excluded from the "don't build dependencies
twice" check but it's currently building dependencies twice! Namely big
dependencies like `rustc-ap-syntax` are built once for rustfmt and once
for the RLS. This commit includes `rustfmt` in these checks and then
fixes the resulting feature mismatches for winapi.

This commit removes all in-tree support for generating backtraces in
favor of depending on the `backtrace` crate on crates.io. This resolves
a very longstanding piece of duplication where the standard library has
long contained the ability to generate a backtrace on panics, but the
code was later extracted and duplicated on crates.io with the
`backtrace` crate. Since that fork each implementation has seen various
improvements one way or another, but typically `backtrace`-the-crate has
lagged behind libstd in one way or another.
The goal here is to remove this duplication of a fairly critical piece
of code and ensure that there's only one source of truth for generating
backtraces between the standard library and the crate on crates.io.
Recently I've been working to bring the `backtrace` crate on crates.io
up to speed with the support in the standard library which includes:
* Support for `StackWalkEx` on MSVC to recover inline frames with
debuginfo.
* Using `libbacktrace` by default on MinGW targets.
* Supporting `libbacktrace` on OSX as an option.
* Ensuring all the requisite support in `backtrace`-the-crate compiles
with `#![no_std]`.
* Updating the `libbacktrace` implementation in `backtrace`-the-crate to
initialize the global state with the correct filename where necessary.
After reviewing the code in libstd the `backtrace` crate should be at
exact feature parity with libstd today. The backtraces generated should
have the same symbols and same number of frames in general, and there's
not known divergence from libstd currently.
Note that one major difference between libstd's backtrace support and
the `backtrace` crate is that on OSX the crates.io crate enables the
`coresymbolication` feature by default. This feature, however, uses
private internal APIs that aren't published for OSX. While they provide
more accurate backtraces this isn't appropriate for libstd distributed
as a binary, so libstd's dependency on the `backtrace` crate explicitly
disables this feature and forces OSX to use `libbacktrace` as a
symbolication strategy.
The long-term goal of this refactoring is to eventually move us towards
a world where we can drop `libbacktrace` entirely and simply use Gimli
and the surrounding crates for backtrace support. That's still aways off
but hopefully will much more easily enabled by having the source of
truth for backtraces live in crates.io!
Procedurally if we go forward with this I'd like to transfer the
`backtrace-rs` crate to the rust-lang GitHub organization as well, but I
figured I'd hold off on that until we get closer to merging.

According to the Cargo Reference:
https://doc.rust-lang.org/cargo/reference/manifest.html
> This is an SPDX 2.1 license expression for this package. Currently
> crates.io will validate the license provided against a whitelist of
> known license and exception identifiers from the SPDX license list
> 2.4. Parentheses are not currently supported.
>
> Multiple licenses can be separated with a `/`, although that usage
> is deprecated. Instead, use a license expression with AND and OR
> operators to get more explicit semantics.

Unfortunately this'll dupe parking_lot until the data_structures crate
is published and be updated in rls in conjunction with crossbeam-channel

Hopefully just another routine update!
So far this starts to enable the `std::arch` in stage0 builds of rustc.
This means that we may need stage0/not(stage0) in stdsimd itself, but
more and more code is starting to use `std::arch` so I think it's time
to start shifting the balance of work here.
|

The last remaining one comes from mdbook. Unfortunately updating it
breaks everything
|
|
Hopefully a relatively routine update!

In addition to to updating Cargo's submodule and Cargo's dependencies,
this also updates Cargo's build to build OpenSSL statically into Cargo
as well as libcurl unconditionally. This removes OpenSSL build logic
from the bootstrap code, and otherwise requests that even on OSX we
build curl statically.

Also update Cargo's dependencies while we're at it

Bring in some fixes for `cargo fix` notably
