We have `File::create` for creating a file or opening an existing file, but the secure way to guarantee creating a new file requires a longhand invocation via `OpenOptions`. Add `File::create_new` to handle this case, to make it easier for people to do secure file creation.
...replacing `.cast().wrapping_offset().cast()` & similar code.

Add a `File::create_new` constructor We have `File::create` for creating a file or opening an existing file, but the secure way to guarantee creating a new file requires a longhand invocation via `OpenOptions`. Add `File::create_new` to handle this case, to make it easier for people to do secure file creation.
…r-errors Remove separate indexing of early-bound regions ~Based on rust-lang#99728 This PR copies some modifications from rust-lang#97839 around object lifetime defaults. These modifications allow to stop counting generic parameters during lifetime resolution, and rely on the indexing given by `rustc_typeck::collect`.
…g, r=JohnTitor Stabilize `std::io::read_to_string` Closes rust-lang#80218. 🎉 This PR stabilizes the `std::io::read_to_string` function, with the following public API: ```rust pub fn read_to_string<R: Read>(reader: R) -> Result<String>; ``` It's analogous to `std::fs::read_to_string` for files, but it works on anything that implements `io::Read`, including `io::stdin()`. See the tracking issue (rust-lang#80218) or documentation for details.
…, r=thomcc Use `DisplayBuffer` for socket addresses. Continuation of rust-lang#100625 for socket addresses. Renames `net::addr` to `net::addr::socket`, `net::ip` to `net::addr::ip` and `net::ip::display_buffer::IpDisplayBuffer` to `net::addr::display_buffer::DisplayBuffer`.

Make use of `[wrapping_]byte_{add,sub}`
These new methods trivially replace old `.cast().wrapping_offset().cast()` & similar code.
Note that [`arith_offset`](https://doc.rust-lang.org/std/intrinsics/fn.arith_offset.html) and `wrapping_offset` are the same thing.
