TLS tests have been deadlocking on the OSX bots for quite some time now and this
commit is the result of the investigation into what's going on. It turns out
that a value in TLS which is being destroyed (e.g. the destructor is run) can be
reset back to the initial state **while the destructor is running** if TLS is
re-accessed.
To fix this we stop calling drop_in_place on OSX and instead move the data to a
temporary location on the stack.
This PR modernizes some names in the type checker. The only remaining snake_case name in ty.rs is `ctxt` which should be resolved by @eddyb's pending refactor. We can bike shed over the names, it would just be nice to bring the type checker inline with modern Rust.

Use escaped byte string representation for CString Debug
Faithfully represent the contents of the CString and CStr in their Debug
impl, by treating them as byte strings with our default escaping to
ascii representation.
Add impl Debug for CStr.
Fixes#26964.
The very first code fragment off every struct and trait documentation page generates wrong playground code. This pull request adjusts ```playpen.js``` to only create a link for real examples.
Documentation:
```rust
pub struct String {
// some fields omitted
}
```
Playground:
```rust
Struct std::String
[−]
[src]
```

Avoids some code duplication and relies less on deprecated properties on `KeyboardEvent`. The code is still looking quite bad, but that’s primarily because interop in this area is a disaster zone.
Sharpens the help dialogues edges by removing border-padding, which
matches better with the rest of the document.
Also increases somewhat the rounded edges of the key symbols to
make it clear they are symbols.
Also introduces closing apostrophes and ellipsis for search field
placeholder.

I noticed in docs, specifically http://doc.rust-lang.org/std/primitive.u8.html#method.is_power_of_two, that it was like this, and it was apparently in multiple places too.
Didn't change any occurrences through the cross-depo things. There's a lot in /src/llvm/ for instance, but I'm not confident on how to go about sending fixes for those, so this is just what's in the base rust depo.

Previously on Windows a directory junction would return false from `is_dir`,
causing various odd behavior, specifically calls to `create_dir_all` might fail
when they would otherwise continue to succeed.
Closes#26716
This makes `Debug` for `File` show the file path and access mode of the file on OS X, just like on Linux.
I'd be happy about any feedback how to make this code better. In particular, I'm not sure how to handle the buffer passed to `fnctl`. This way works, but it feels a bit cumbersome. `fcntl` unfortunately doesn't return the length of the path.
