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.
