Update Windows Argument Parsing Fixes #44650 The Windows command line is passed to applications [as a single string](https://docs.microsoft.com/en-us/archive/blogs/larryosterman/the-windows-command-line-is-just-a-string) which the application then parses to get a list of arguments. The standard rules (as used by C/C++) for parsing the command line have slightly changed over the years, most recently in 2008 which added new escaping rules. This PR implements the new rules as [described on MSDN](https://docs.microsoft.com/en-us/cpp/cpp/main-function-command-line-args?view=msvc-160#parsing-c-command-line-arguments) and [further detailed here](https://daviddeley.com/autohotkey/parameters/parameters.htm#WIN). It has been tested against the behaviour of C++ by calling a C++ program that outputs its raw command line and the contents of `argv`. See [my repo](https://github.com/ChrisDenton/winarg/tree/std) if anyone wants to reproduce my work. For an overview of how this PR changes argument parsing behavior and why we feel it is warranted see https://github.com/rust-lang/rust/pull/87580#issuecomment-893833893. For some examples see: https://github.com/rust-lang/rust/pull/87580#issuecomment-894299249

Allow writing of incomplete UTF-8 sequences to the Windows console via stdout/stderr # Problem Writes of just an incomplete UTF-8 byte sequence (e.g. `b"\xC3"` or `b"\xF0\x9F"`) to stdout/stderr with a Windows console attached error with `io::ErrorKind::InvalidData, "Windows stdio in console mode does not support writing non-UTF-8 byte sequences"` even though further writes could complete the codepoint. This is currently a rare occurence since the [linewritershim](https://github.com/rust-lang/rust/blob/2c56ea38b045624dc8b42ec948fc169eaff1206a/library/std/src/io/buffered/linewritershim.rs) implementation flushes complete lines immediately and buffers up to 1024 bytes for incomplete lines. It can still happen as described in #83258. The problem will become more pronounced once the developer can switch stdout/stderr from line-buffered to block-buffered or immediate when the changes in the "Switchable buffering for Stdout" pull request (#78515) get merged. # Patch description If there is at least one valid UTF-8 codepoint all valid UTF-8 is passed through to the extracted `write_valid_utf8_to_console()` fn. The new code only comes into play if `write()` is being passed a short byte slice comprising an incomplete UTF-8 codepoint. In this case up to three bytes are buffered in the `IncompleteUtf8` struct associated with `Stdout` / `Stderr`. The bytes are accepted one at a time. As soon as an error can be detected `io::ErrorKind::InvalidData, "Windows stdio in console mode does not support writing non-UTF-8 byte sequences"` is returned. Once a complete UTF-8 codepoint is received it is passed to the `write_valid_utf8_to_console()` and the buffer length is set to zero. Calling `flush()` will neither error nor write anything if an incomplete codepoint is present in the buffer. # Tests Currently there are no Windows-specific tests for console writing code at all. Writing (regression) tests for this problem is a bit challenging since unit tests and UI tests don't run in a console and suddenly popping up another console window might be surprising to developers running the testsuite and it might not work at all in CI builds. To just test the new functionality in unit tests the code would need to be refactored. Some guidance on how to proceed would be appreciated. # Public API changes * `std::str::verifications::utf8_char_width()` would be exposed as `std::str::utf8_char_width()` behind the "str_internals" feature gate. # Related issues * Fixes #83258. * PR #78515 will exacerbate the problem. # Open questions * Add tests? * Squash into one commit with better commit message?

rustdoc: Box `GenericArgs::Parenthesized.output` Split out from #88379. This reduces the size of `GenericArgs` from 104 bytes to 56 bytes, essentially reducing it by half. `GenericArgs` is one of the fields of `PathSegment`, so this should reduce the amount of memory allocated for `PathSegment`s in the cases where the generics are not for a `Fn`, `FnMut`, or `FnOnce` trait. r? `@jyn514`

Stabilize `UnsafeCell::raw_get()` This PR stabilizes the associated function `UnsafeCell::raw_get()`. The FCP has [already completed](https://github.com/rust-lang/rust/issues/66358#issuecomment-899095068). While there was some discussion about the naming after the close of the FCP, it looks like people have agreed on this name. Still, it would probably be best if a `libs-api` member had a look at this and stated whether more discussion is needed. While I was at it, I added some tests for `UnsafeCell`, because there were barely any. Closes #66358.

Use the return value of readdir_r() instead of errno POSIX says: > If successful, the readdir_r() function shall return zero; otherwise, > an error number shall be returned to indicate the error. But we were previously using errno instead of the return value. This led to issue #86649.

BTree: remove Ord bound from new `K: Ord` bound is unnecessary on `BTree{Map,Set}::new` and their `Default` impl. No elements exist so there are nothing to compare anyway, so I don't think "future proof" would be a blocker here. This is analogous to `HashMap::new` not having a `K: Eq + Hash` bound. #79245 originally does this and for some reason drops the change to `new` and `Default`. I can see why changes to other methods like `entry` or `symmetric_difference` need to be careful but I couldn't find out any reason not to do it on `new`. Removing the bound also makes the stabilisation of `const fn new` not depending on const trait bounds. cc `@steffahn` who suggests me to make this PR. r? `@dtolnay`

Emit specific warning to clarify that `#[no_mangle]` should not be applied on foreign statics or functions Foreign statics and foreign functions should not have `#[no_mangle]` applied, as it does nothing to the name and has some extra hidden behavior that is normally unwanted. There was an existing warning for this, but it says the attribute is only allowed on "statics or functions", which to the user can be confusing. This PR adds a specific version of the unused `#[no_mangle]` warning that explains that the target is a *foreign* static or function and that they do not need the attribute. Fixes #78989

Add bit removal methods to SparseBitMatrix and factor *BitSet relational methods into more extensible trait I need the ability to clear the bits out of a row from `SparseBitMatrix`. Currently, all the mutating methods only allow insertion of bits, and there is no way to get access to the underlying data. One approach is simply to make `ensure_row` public, since it grants `&mut` access to the underlying `HybridBitSet`. This PR adds the `pub` modifier. However, presumably this method was private for a reason, so I'm open to other designs. I would prefer general mutable access to the rows, because that way I can add many mutating operations (`clear`, `intersect`, etc.) without filing a PR each time :-) r? `@ecstatic-morse`

Introduce `let...else` Tracking issue: #87335 The trickiest part for me was enforcing the diverging else block with clear diagnostics. Perhaps the obvious solution is to expand to `let _: ! = ..`, but I decided against this because, when a "mismatched type" error is found in typeck, there is no way to trace where in the HIR the expected type originated, AFAICT. In order to pass down this information, I believe we should introduce `Expectation::LetElseNever(HirId)` or maybe add `HirId` to `Expectation::HasType`, but I left that as a future enhancement. For now, I simply assert that the block is `!` with a custom `ObligationCauseCode`, and I think this is clear enough, at least to start. The downside here is that the error points at the entire block rather than the specific expression with the wrong type. I left a todo to this effect. Overall, I believe this PR is feature-complete with regard to the RFC.

Concrete regions can show up in mir borrowck if the originated from there We used to not encounter them here, because we took regions from typeck's opaque type resolution by renumbering them. We don't do that anymore. Instead mir borrock does all the logic, and it can handle concrete regions just fine, as long as it created them itself. fixes #83190 which was introduced by #87287 r? `@spastorino`
