Replace `winapi` with `windows-sys` crate.
### What does this PR try to resolve?
replace `winapi` with `windows-sys` crate.
It's officially maintained.
### How should we test and review this PR?
I just do the replacement of API. I think it is quite clear.
And I found a `cfg` for `windows` may miss checked error.
### Additional information
No one.
Make cargo aware of dwp files.
When using -Csplit-debuginfo=packed on Linux, rustc will produce a dwp file. Unlike the dwo files, whose paths are embedded into the binary, there's no information in the binary to help a debugger locate a dwp file. By convention, the dwp file for `<EXE>` is given the name `<EXE>.dwp` and placed next to `<EXE>`.
When cargo hardlinks the executable file rustc put in target/debug/deps into target/debug, it also needs to hardlink the dwp file along with it. Failing to do this prevents the debugger from finding the dwp file when the binary is executed from target/debug, as there's no way for the debugger to know to look in the deps subdirectory.
The split_debuginfo option is passed down into file_types to make this possible. For cargo clean manual handling is added to match the other split_debuginfo files. bin_link_for_target also passes in None because it won't care about the dwp file.

Change rustdoc-scrape-examples to be a target-level configuration
This PR addresses issues raised in rust-lang/cargo#9525. Specifically:
1. It enables examples to be scraped from `#[test]` functions, by passing additional flags to Rustdoc to ensure that these functions aren't ignored by rustc.
2. It moves the `arg` from `-Z rustdoc-scrape-examples={arg}` into a target-level configuration that can be added to Cargo.toml.
The added test `scrape_examples_configure_target` shows a concrete example. In short, examples will be default scraped from Example and Lib targets. Then the user can enable or disable scraping like so:
```toml
[lib]
doc-scrape-examples = false
[[test]]
name = "my_test"
doc-scrape-examples = true
```
chore: Upgrade dependencies
This upgrades several dependencies to the latest "major" release. The original intent was just to get onto the latest snapbox but I noticed several others that could be updated and thought "why not".
- `snapbox` broke compatibility on less used APIs
- Its unclear from the docs if `miow` or `remove_dir_all` even broke compatibility
I did not touch `mdman` as that has several large, stale deps
Make cargo forward pre-existing CARGO if set
Currently, Cargo will always set `$CARGO` to point to what it detects its own path to be (using `std::env::current_exe`). Unfortunately, this runs into trouble when Cargo is used as a library, or when `current_exe` is not actually the binary itself (e.g., when invoked through Valgrind or `ld.so`), since `$CARGO` will not point at something that can be used as `cargo`. This, in turn, means that users can't currently rely on `$CARGO` to do the right thing, and will sometimes have to invoke `cargo` directly from `$PATH` instead, which may not reflect the `cargo` that's currently in use.
This patch makes Cargo re-use the existing value of `$CARGO` if it's already set in the environment. For Cargo subcommands, this will mean that the initial invocation of `cargo` in `cargo foo` will set `$CARGO`, and then Cargo-as-a-library inside of `cargo-foo` will inherit that (correct) value instead of overwriting it with the incorrect value `cargo-foo`. For other execution environments that do not have `cargo` in their call stack, it gives them the opportunity to set a working value for `$CARGO`.
One note about the implementation of this is that the test suite now needs to override `$CARGO` explicitly so that the _user's_ `$CARGO` does not interfere with the contents of the tests. It _could_ remove `$CARGO` instead, but overriding it seemed less error-prone.
Fixes#10119.

Originally, crates.io would block on publish requests until the publish
was complete, giving `cargo publish` this behavior by extension. When
crates.io switched to asynchronous publishing, this intermittently broke
people's workflows when publishing multiple crates. I say interittent
because it usually works until it doesn't and it is unclear why to the
end user because it will be published by the time they check. In the
end, callers tend to either put in timeouts (and pray), poll the
server's API, or use `crates-index` crate to poll the index.
This isn't sufficient because
- For any new interested party, this is a pit of failure they'll fall
into
- crates-index has re-implemented index support incorrectly in the past,
currently doesn't handle auth, doesn't support `git-cli`, etc.
- None of these previous options work if we were to implement
workspace-publish support (#1169)
- The new sparse registry might increase the publish times, making the
delay easier to hit manually
- The new sparse registry goes through CDNs so checking the server's API
might not be sufficient
- Once the sparse registry is available, crates-index users will find
out when the package is ready in git but it might not be ready through
the sparse registry because of CDNs
This introduces unstable support for blocking by setting
`publish.timeout` to non-zero value.
A step towards #9507
Bump git2 to 0.15 and libgit2-sys to 0.14
This will allow cargo to avoid vendored builds of git2 in up-to-date
environments going forward, and brings in the [libgit2 1.4.4 CVE fix].

In writing the contrib documentation for functional vs ui tests, I
realized that as we work to make snapbox work for the functional tests,
we'll need distinct `Assert` objects since we'll want to elide a lot
more content in functional tests. I'm making room for this by
qualifying the existing asserts as being for "ui".
Improve integration of the http server introduced by the http-registry feature.
Now the same HTTP server is used for serving downloads, the index, and
the API.
This makes it easier to write tests that deal with authentication and
http registries.
Git lets users define the default update/checkout strategy for a submodule
by setting the `submodule.<name>.update` key in `.gitmodules` file.
If the update strategy is `none`, the submodule will be skipped during
update. It will not be fetched and checked out:
1. *foo* is a big git repo
```
/tmp $ git init foo
Initialized empty Git repository in /tmp/foo/.git/
/tmp $ dd if=/dev/zero of=foo/big bs=1000M count=1
1+0 records in
1+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 0.482087 s, 2.2 GB/s
/tmp $ git -C foo add big
/tmp $ git -C foo commit -m 'I am big'
[main (root-commit) 84fb533] I am big
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 big
```
2. *bar* is a repo with a big submodule with `update=none`
```
/tmp $ git init bar
Initialized empty Git repository in /tmp/bar/.git/
/tmp $ git -C bar submodule add file:///tmp/foo foo
Cloning into '/tmp/bar/foo'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 1 (delta 0), pack-reused 0

/tmp $ git -C bar config --file .gitmodules submodule.foo.update none
/tmp $ cat bar/.gitmodules
[submodule "foo"]
path = foo
url = file:///tmp/foo
update = none
/tmp $ git -C bar commit --all -m 'I have a big submodule with update=none'
[main (root-commit) 6c355ea] I have a big submodule not updated by default
2 files changed, 4 insertions(+)
create mode 100644 .gitmodules
create mode 160000 foo
```
3. *baz* is a clone of *bar*, notice *foo* submodule gets skipped
```
/tmp $ git clone --recurse-submodules file:///tmp/bar baz
Cloning into 'baz'...
remote: Enumerating objects: 3, done.
remote: Counting objects: 100% (3/3), done.
remote: Compressing objects: 100% (3/3), done.

Submodule 'foo' (file:///tmp/foo) registered for path 'foo'
Skipping submodule 'foo'
/tmp $ git -C baz submodule update --init
Skipping submodule 'foo'
/tmp $
```
Cargo, on the other hand, ignores the submodule update strategy set in
`.gitmodules` properties when updating dependencies. Such behavior can
be considered against the wish of the crate publisher.
4. *bar* is now a lib with a big submodule with update disabled
```
/tmp $ cargo init --lib bar
Created library package
/tmp $ git -C bar add .
/tmp $ git -C bar commit -m 'I am a lib with a big submodule but update=none'
[main eb07cf7] I am a lib with a big submodule but update=none
3 files changed, 18 insertions(+)
create mode 100644 .gitignore
create mode 100644 Cargo.toml
create mode 100644 src/lib.rs
/tmp $
```
5. *qux* depends on *bar*, notice *bar*'s submodules are fetched
```
/tmp $ cargo init qux && cd qux
Created binary (application) package
/tmp/qux $ echo -e '[dependencies.bar]\ngit = "file:///tmp/bar"' >> Cargo.toml
/tmp/qux $ time cargo update
Updating git repository `file:///tmp/bar`
Updating git submodule `file:///tmp/foo`
real 0m22.182s
user 0m20.402s
sys 0m1.714s
/tmp/qux $
```
Fix it by checking if a Git repository submodule should be updated when
cargo processes dependencies.
6. With the change applied, submodules with `update=none` are skipped
```
/tmp/qux $ cargo cache -a > /dev/null
/tmp/qux $ time ~/src/cargo/target/debug/cargo update
Updating git repository `file:///tmp/bar`
Skipping git submodule `file:///tmp/foo`
real 0m0.029s
user 0m0.021s
sys 0m0.008s
/tmp/qux $
```

When running tests in the `rust-lang/cargo` repo, `file!` is relative to
the crate root and tests are run relative to the crate root and
everything is fine.
When running tests in the `rust-lang/rust` repo, `file!` is relative to
the workspace root and tests are run relative to the crate root and
there is much sadness.
If we are compiling relative to the crate root, we could make the path
absolute and everything would be dandy but this needs to happen at
compile time. Didn't see a way to do this.
We could stop using `curr_dir` but that makes the tests a bit noisier
with more overhead for creating a new tests from an existing case.
Since we can reasonly know what all roots will be used for `file!`, we
can just hard code-in support for those two roots. Much happiness
ensues as everything works with this surgical hack.
