to avoid panic for invalid Unicode scalar values
Improve the documentation of drain members hopefully fixes rust-lang#92765

rustdoc-json: buffer output
It turns out we were doing syscalls for each part of the json syntax
Before:
```
...
[pid 1801267] write(5, "\"", 1) = 1
[pid 1801267] write(5, ",", 1) = 1
[pid 1801267] write(5, "\"", 1) = 1
...
```
After:
```
[pid 1974821] write(5, "{\"root\":\"0:0\",\"crate_version\":nu"..., 1575) = 1575
```
In one benchmark (one struct, almost all time in `std`), this gives ~2x perf

Add debug assertions to validate NUL terminator in c strings The `unchecked` variants from the stdlib usually perform the check anyway if debug assertions are on (for example, `unwrap_unchecked`). This PR does the same thing for `CStr` and `CString`, validating the correctness for the NUL byte in debug mode.
pre rust-lang#89862 cleanup changes used in rust-lang#89862 which can be landed without the rest of this PR being finished. r? `@estebank`
Use a `Field` in `ConstraintCategory::ClosureUpvar` As part of rust-lang#90317, we do not want `HirId` to implement `Ord`, `PartialOrd`. This line of code has made that difficult https://github.com/rust-lang/rust/blob/1b27144afc77031ba9c05d86c06c64485589775a/compiler/rustc_borrowck/src/region_infer/mod.rs#L2184 since it sorts a [`ConstraintCategory::ClosureUpvar(HirId)`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/enum.ConstraintCategory.html#variant.ClosureUpvar). This PR makes that variant take a [`Field`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/struct.Field.html) instead. r? `@nikomatsakis`
