This commit applies all stabilizations, renamings, and deprecations that the library team has decided on for the upcoming 1.9 release. All tracking issues have gone through a cycle-long "final comment period" and the specific APIs stabilized/deprecated are: Stable * `std::panic` * `std::panic::catch_unwind` (renamed from `recover`) * `std::panic::resume_unwind` (renamed from `propagate`) * `std::panic::AssertUnwindSafe` (renamed from `AssertRecoverSafe`) * `std::panic::UnwindSafe` (renamed from `RecoverSafe`) * `str::is_char_boundary` * `<*const T>::as_ref` * `<*mut T>::as_ref` * `<*mut T>::as_mut` * `AsciiExt::make_ascii_uppercase` * `AsciiExt::make_ascii_lowercase` * `char::decode_utf16` * `char::DecodeUtf16` * `char::DecodeUtf16Error` * `char::DecodeUtf16Error::unpaired_surrogate` * `BTreeSet::take` * `BTreeSet::replace` * `BTreeSet::get` * `HashSet::take` * `HashSet::replace` * `HashSet::get` * `OsString::with_capacity` * `OsString::clear` * `OsString::capacity` * `OsString::reserve` * `OsString::reserve_exact` * `OsStr::is_empty` * `OsStr::len` * `std::os::unix::thread` * `RawPthread` * `JoinHandleExt` * `JoinHandleExt::as_pthread_t` * `JoinHandleExt::into_pthread_t` * `HashSet::hasher` * `HashMap::hasher` * `CommandExt::exec` * `File::try_clone` * `SocketAddr::set_ip` * `SocketAddr::set_port` * `SocketAddrV4::set_ip` * `SocketAddrV4::set_port` * `SocketAddrV6::set_ip` * `SocketAddrV6::set_port` * `SocketAddrV6::set_flowinfo` * `SocketAddrV6::set_scope_id` * `<[T]>::copy_from_slice` * `ptr::read_volatile` * `ptr::write_volatile` * The `#[deprecated]` attribute * `OpenOptions::create_new` Deprecated * `std::raw::Slice` - use raw parts of `slice` module instead * `std::raw::Repr` - use raw parts of `slice` module instead * `str::char_range_at` - use slicing plus `chars()` plus `len_utf8` * `str::char_range_at_reverse` - use slicing plus `chars().rev()` plus `len_utf8` * `str::char_at` - use slicing plus `chars()` * `str::char_at_reverse` - use slicing plus `chars().rev()` * `str::slice_shift_char` - use `chars()` plus `Chars::as_str` * `CommandExt::session_leader` - use `before_exec` instead. Closes #27719 cc #27751 (deprecating the `Slice` bits) Closes #27754 Closes #27780 Closes #27809 Closes #27811 Closes #27830 Closes #28050 Closes #29453 Closes #29791 Closes #29935 Closes #30014 Closes #30752 Closes #31262 cc #31398 (still need to deal with `before_exec`) Closes #31405 Closes #31572 Closes #31755 Closes #31756
