* Make sure private consts are stripped.
* Don't show a code block for the value if there is none.
* Make sure default values are shown in impls.
* Make sure docs from the trait are used if the impl has no docs.

rustdoc: Stop stripping empty modules
There is no good reason to strip empty modules with no documentation and
doing so causes subtle problems.
Fixes #42590

Currently rustdoc will fail if passed `-o foo/doc` if the `foo`
directory doesn't exist.
Also remove unneeded `mkdir` as `create_dir_all` can now handle
concurrent invocations.

This improves #32077, but is not a complete fix. For a type alias `type
NewType = AliasedType`, it will include any `impl NewType` and `impl
Trait for NewType` blocks in the documentation for `NewType`.
A complete fix would include the implementations from the aliased type
in the type alias' documentation, so that users have a complete
picture of methods that are available on the alias. However, to do this
properly would require a fix for #14072, as the alias may affect the
type parameters of the type alias, making the documentation difficult to
understand. (That is, for `type Result = std::result::Result<(), ()>` we
would ideally show documentation for `impl Result<(), ()>`, rather than
generic documentation for `impl<T, E> Result<T, E>`).
I think this improvement is worthwhile, as it exposes implementations
which are not currently documented by rustdoc. The documentation for the
implementations on the aliased type are still accessible by clicking
through to the docs for that type. (Although perhaps it's now less
obvious to the user that they should click-through to get there).

These methods can never be called through deref so there is no point
including them. For example you can't call `into_boxed_bytes` or
`into_string` on `String`.
|
|
Rather than (ab)using Debug for outputting the type in plain text use the
alternate format parameter which already does exactly that. This fixes
type parameters for example which would output raw HTML.
Also cleans up adding parens around references to trait objects.

rustdoc: add a list of headings to the sidebar
It's another misdreavus rustdoc PR, which means it's time for Bikeshed City once again! `:3`
In an effort to aid navigation in long documentation pages, this PR adds a listing of headings to the sidebars of pages where such headings exist. For example, for structs, links to their fields, inherent methods, and trait implementations are available where applicable.
Examples:
* Modules/Crate roots
* Enums
* Primitives
* Traits
* Structs
Open questions:
* Right now, these kinds of pages (and also unions) are the only pages that will receive the name header - pages for functions, constants, macros, etc, won't have the corresponding name in their sidebar. Should I print the name regardless and only add table-of-contents links for pages that have them? This would make them match, for example, a struct with no public fields, no methods, and no trait implementations. The latter would still have a "Struct MyStruct" line above the module contents, with no header links to speak of, whereas a function wouldn't even have "Function my\_function".
* This is only a header listing, but there has been requests to include a more-complete listing of fields/methods/traits/etc, for example in #41123.

- add spaces to output so stripping lines and breaking spaces renders
the same
- add commas to where clauses in rustdoc tests to match the new output
|
|
Instead of rendering all of the HTML in rustdoc this relies on
pulldown-cmark's `push_html` to do most of the work. A few iterator
adapters are used to make rustdoc specific modifications to the output.
This also fixes MarkdownHtml and link titles in plain_summary_line.

Fix for #39596: sort Trait2 before Trait10.
This is a change discussed in #39596. Essentially, item names will be sorted as if they're (&str, u64) pairs instead of just `&str`, meaning that `"Apple" < "Banana"` and also `"Fruit10" > "Fruit2"`.
Sample sorting:
1. Apple
2. Banana
3. Fruit
4. Fruit0
5. Fruit00
6. Fruit1
7. Fruit01
8. Fruit2
9. Fruit02
10. Fruit20
11. Fruit100
12. Pear

`TokenStream`-based attributes, paths in attribute and derive macro invocations
This PR
- refactors `Attribute` to use `Path` and `TokenStream` instead of `MetaItem`.
- supports macro invocation paths for attribute procedural macros.
- e.g. `#[::foo::attr_macro] struct S;`, `#[cfg_attr(all(), foo::attr_macro)] struct S;`
- supports macro invocation paths for derive procedural macros.
- e.g. `#[derive(foo::Bar, super::Baz)] struct S;`
- supports arbitrary tokens as arguments to attribute procedural macros.
- e.g. `#[foo::attr_macro arbitrary + tokens] struct S;`
- supports using arbitrary tokens in "inert attributes" with derive procedural macros.
- e.g. `#[derive(Foo)] struct S(#[inert arbitrary + tokens] i32);`
where `#[proc_macro_derive(Foo, attributes(inert))]`

The generates HTML can contain quotes so we need to make sure they are
escaped before inserting into the js files.

rustdoc: Only include a stability span if needed.
This patch gets rid of the empty stability boxes in docs by only including the span that creates it when the item actually has a stability class.
Here are images of the issue on `std::process::Output`:

This is my first non-trivial patch to Rust, so I'm sure some of my approach is not idiomatic. Let me know how you'd like me to adjust!

rustdoc: Show attributes on all item types
Currently attributes are only shown for structs, unions and enums but
they should be shown for all items. For example it is useful to know if a
function is `#[no_mangle]`.

* 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.
