This release introduces the Buffer trait, which is used in read, pread, recv, recvfrom, getrandom, readlinkat_raw, epoll::wait, kevent, port::getn, getxattr, lgetxattr, fgetxattr, listxattr, llistxattr, and flistxattr, and adds support for reading data into uninitialized buffers, as well as safely reading data into the spare capacity of Vecs.

This release also simplifies the way network addresses are handled. Instead of having separate functions with _v4, _v6, _unix, _xdp, and now _netlink suffixes, rustix now uses a SocketAddrArg trait so that functions such as bind, connect, sendto, and sendmsg_addr can accept any type of address, and are easier to extend to new address types in the future.

And, this release simplifies the ioctl API, replacing opcode wrapper types with const generics.

This updates several APIs to add Linux 6.13 features, and raw linux-raw-sys types are no longer exposed in the public API, so it should be easier to stay up to date with new Linux releases.

And many more new features, bug fixes, and cleanups. See the CHANGES.md file for the full list of breaking changes.
