Allow raw lint descriptions
update_lints now understands raw strings in declare_clippy_lint descriptions.
Supersedes #8655
cc `@Alexendoo` thanks for addressing this so quickly. I build a little bit simpler version of your patch. I don't think it really matters what `Literal` we're trying to tokenize, since we assume later, that it is some sort of `str`.

…abs()
changelog: Add a [`cast_abs_to_unsigned`] that checks for uses of `abs()` that are cast to the corresponding unsigned integer type and suggest to replace them with `unsigned_abs()`.

Use gender neutral terms
#95508 was not executed well, but it did find a couple of legitimate issues: some uses of unnecessarily gendered language, and some typos. This PR fixes (properly) the legitimate issues it found.
Correct safety reasoning in `str::make_ascii_{lower,upper}case()`
I don't understand why the previous comment was used (it was inserted in #66564), but it doesn't explain why these functions are safe, only why `str::as_bytes{_mut}()` are safe.
If someone thinks they make perfect sense, I'm fine with closing this PR.
Regression test for #82866
Saw that this issue was open when i was cleaning my old branch for #92237.
I am also not opposed to not adding an extra test and just closing #82866.
Fixes#82866
Stop flagging unexpected inner attributes as outer ones in certain diagnostics
Fixes#94340.
In the issue to-be-fixed I write that the general message _an inner attribute is not permitted in this context_ should be more specific noting that the “context” is the `include` macro. This, however, cannot be achieved without touching a lot of things and passing a flag to the `parse_expr` and `parse_item` calls in `expand_include`. This seems rather hacky to me. That's why I left it as it. `Span::from_expansion` does not apply either AFAIK.

Bump bootstrap compiler to 1.61.0 beta
This PR bumps the bootstrap compiler to the 1.61.0 beta. The first commit changes the stage0 compiler, the second commit applies the "mechanical" changes and the third and fourth commits apply changes explained in the relevant comments.

Mention `std::env::var` in `env!`
When searching for how to read an environment variable, I first encountered the `env!` macro. It would have been useful to me if the documentation had included a link to `std::env::var`, which is what I was actually looking for.

This allows copy pasting the path or using Ctrl+Click in IDEs to go directly to the file, instead of having to edit the filename first.
By heap allocating the argument within `NtPath`, `NtVis`, and `NtStmt`.
This slightly reduces cumulative and peak allocation amounts, most
notably on `deep-vector`.
Update libc to 0.2.121
With the updated libc, UNIX stack overflow handling in libstd can now
use the common `si_addr` accessor function, rather than attempting to
use a field from that name in `siginfo_t`. This simplifies the
collection of the fault address, particularly on platforms where that
data resides within a union in `siginfo_t`.
Improve terse test output.
The current terse output gives 112 chars per line, which causes
wraparound for people using 100 char wide terminals, which is very
common.
This commit changes it to be exactly 100 wide, which makes the output
look much nicer.
Don't cast thread name to an integer for prctl
`libc::prctl` and the `prctl` definitions in glibc, musl, and the kernel headers are C variadic functions. Therefore, all the arguments (except for the first) are untyped. It is only the Linux man page which says that `prctl` takes 4 `unsigned long` arguments. I have no idea why it says this.
In any case, the upshot is that we don't need to cast the pointer to an integer and confuse Miri.
But in light of this... what are we doing with those three `0`s? We're passing 3 `i32`s to `prctl`, which doesn't fill me with confidence. The man page says `unsigned long` and all the constants in the linux kernel are macros for expressions of the form `1UL << N`. I'm mostly commenting on this because looks a whole lot like some UB that was found in SQLite a few years ago: <https://youtu.be/LbzbHWdLAI0?t=1925> that was related to accidentally passing a 32-bit value from a literal `0` instead of a pointer-sized value. This happens to work on x86 due to the size of pointers and happens to work on x86_64 due to the calling convention. But also, there is no good reason for an implementation to be looking at those arguments. Some other calls to `prctl` require that other arguments be zeroed, but not `PR_SET_NAME`... so why are we even passing them?
I would prefer to end such questions by either passing 3 `libc::c_ulong`, or not passing those at all, but I'm not sure which is better.
