1779: Upgrade libc to 0.2.127 r=asomers a=rtzoeller This is the last version of libc which will support Rust 1.46, per https://github.com/rust-lang/libc/pull/2845. I think we should ship nix 0.25.0 against this version of libc (at some point, not necessarily now), as it will allow us to maintain an MSRV of 1.46, and subsequently upgrade to a later libc immediately after releasing 0.25.0.

1768: Add ETH_P_ALL protocol number to SockProtocol r=asomers a=valdaarhun Hi. I am working on a networking project that uses [packet sockets](https://man7.org/linux/man-pages/man7/packet.7.html) and noticed that ETH_P_ALL is not there in the `SockProtocol` enum. I thought it would be nice to have it here alongside IPPROTO_TCP and IPPROTO_UDP instead of having to separately import it from the libc crate. Co-authored-by: valdaarhun <icegambit91@gmail.com>

1770: Fix SockaddrLike::from_raw with unaligned inputs r=rtzoeller a=asomers The major users of this function are functions like gethostname, which will always properly align their buffers. But out-of-crate consumers could manually construct an unaligned buffer. Handle that correctly. Enable Clippy's cast_ptr_alignment lint. It's disabled by default as it reports many false positives, but it would've caught this problem. Reported-by: Miri Fixes: 1769 Co-authored-by: Alan Somers <asomers@gmail.com>

1741: SigSet: A new unsafe helper method to create a SigSet from a sigset_t r=rtzoeller a=germag Currently, the only way to create a `SigSet` from a `sigset_t` object is by using pointer casts, like: ``` unsafe { let sigset = *(&sigset as *const libc::sigset_t as *const SigSet) }; ``` This is un-ergonomic for library creators with interfaces to C. So, let's add a new unsafe method that creates a `SigSet` from a `libc::sigset_t` object. We can't implement `From` since converting from `libc::sigset_t` to `SigSet` is unsafe, because objects of type `libc::sigset_t` must be initialized by calling either `sigemptyset(3)` or `sigfillset(3)` before being used. In other case, the results are undefined. We can't implement `TryFrom` either, because there is no way to check if an object of type `libc::sigset_t` is initialized.

1761: Add non-standard Linux `SysconfVar` variants r=asomers a=stevenengler Closes #1240. You can find these options near the end of https://man7.org/linux/man-pages/man3/sysconf.3.html.
