std: Stabilize the `io` module The new `std::io` module has had some time to bake now, and this commit stabilizes its functionality. There are still portions of the module which remain unstable, and below contains a summart of the actions taken. This commit also deprecates the entire contents of the `old_io` module in a blanket fashion. All APIs should now have a reasonable replacement in the new I/O modules. Stable APIs: * `std::io` (the name) * `std::io::prelude` (the name) * `Read` * `Read::read` * `Read::{read_to_end, read_to_string}` after being modified to return a `usize` for the number of bytes read. * `Write` * `Write::write` * `Write::{write_all, write_fmt}` * `BufRead` * `BufRead::{fill_buf, consume}` * `BufRead::{read_line, read_until}` after being modified to return a `usize` for the number of bytes read. * `BufReader` * `BufReader::{new, with_capacity}` * `BufReader::{get_ref, get_mut, into_inner}` * `{Read,BufRead} for BufReader` * `BufWriter` * `BufWriter::{new, with_capacity}` * `BufWriter::{get_ref, get_mut, into_inner}` * `Write for BufWriter` * `IntoInnerError` * `IntoInnerError::{error, into_inner}` * `{Error,Display} for IntoInnerError` * `LineWriter` * `LineWriter::{new, with_capacity}` - `with_capacity` was added * `LineWriter::{get_ref, get_mut, into_inner}` - `get_mut` was added) * `Write for LineWriter` * `BufStream` * `BufStream::{new, with_capacities}` * `BufStream::{get_ref, get_mut, into_inner}` * `{BufRead,Read,Write} for BufStream` * `stdin` * `Stdin` * `Stdin::lock` * `Stdin::read_line` - added method * `StdinLock` * `Read for Stdin` * `{Read,BufRead} for StdinLock` * `stdout` * `Stdout` * `Stdout::lock` * `StdoutLock` * `Write for Stdout` * `Write for StdoutLock` * `stderr` * `Stderr` * `Stderr::lock` * `StderrLock` * `Write for Stderr` * `Write for StderrLock` * `io::Result` * `io::Error` * `io::Error::last_os_error` * `{Display, Error} for Error` Unstable APIs: (reasons can be found in the commit itself) * `Write::flush` * `Seek` * `ErrorKind` * `Error::new` * `Error::from_os_error` * `Error::kind` Deprecated APIs * `Error::description` - available via the `Error` trait * `Error::detail` - available via the `Display` implementation * `thread::Builder::{stdout, stderr}` Changes in functionality: * `old_io::stdio::set_stderr` is now a noop as the infrastructure for printing backtraces has migrated to `std::io`. * The `ReadExt`, `WriteExt`, and `BufReadExt` extension traits were all removed by folding functionality into the corresponding trait.

std: Stabilize library APIs for 1.5 This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)
