Yet another attempt to make the prose on the std crate page
clearer and more informative.
This does a lot of things: tightens up the opening, adds useful links
(including a link to the search bar), offers guidance on how to use
the docs, and expands the prelude docs as a useful newbie entrypoint.

I happened past a comment that asked for functionality that we now have.

We needed a more efficient way to zerofill the vector in read_to_end.
This to reduce the memory intialization overhead to a minimum.
Use the implementation of `std::vec::from_elem` (used for the vec![]
macro) for Vec::resize as well. For simple element types like u8, this
compiles to memset, so it makes Vec::resize much more efficient.

Just like the original article our Windows TLS support is based on predicted,
this symbol must be linked in on MSVC to pull in the necessary support for TLS
variables. This commit fixes a number of unit tests which require that TLS
destructors are run.

"Rust" and "The Rust Standard Library" are capitalized.

It looks like a lot of this dated to previous incarnations of the io
module, etc., and went unused in the reworking leading up to 1.0. Remove
everything we're not actively using (except for signal handling, which
will be reworked in the next commit).

This commit also deprecates the `as_string` and `as_slice` free functions in the
`string` and `vec` modules.

This commit shards the broad `core` feature of the libcore library into finer
grained features. This split groups together similar APIs and enables tracking
each API separately, giving a better sense of where each feature is within the
stabilization process.
A few minor APIs were deprecated along the way:
* Iterator::reverse_in_place
* marker::NoCopy

Sounds better to me this way.

Attempted to organize them in a way more relevant to what newbies
would be interested in hearing.

This API was exercised in a few tests and mirrors the `from_str_radix`
functionality of the integer types.

This commit removes all the old casting/generic traits from `std::num` that are
no longer in use by the standard library. This additionally removes the old
`strconv` module which has not seen much use in quite a long time. All generic
functionality has been supplanted with traits in the `num` crate and the
`strconv` module is supplanted with the [rust-strconv crate][rust-strconv].

This is a breaking change due to the removal of these deprecated crates, and the
alternative crates are listed above.

This patch
1. renames libunicode to librustc_unicode,
2. deprecates several pieces of libunicode (see below), and
3. removes references to deprecated functions from
librustc_driver and libsyntax. This may change pretty-printed
output from these modules in cases involving wide or combining
characters used in filenames, identifiers, etc.
The following functions are marked deprecated:
1. char.width() and str.width():
--> use unicode-width crate
2. str.graphemes() and str.grapheme_indices():
--> use unicode-segmentation crate
3. str.nfd_chars(), str.nfkd_chars(), str.nfc_chars(), str.nfkc_chars(),
char.compose(), char.decompose_canonical(), char.decompose_compatible(),
char.canonical_combining_class():
--> use unicode-normalization crate

Needed to get modules like rustc_back::tempdir compiling.
|
|
This commit entirely removes the old I/O, path, and rand modules. All
functionality has been deprecated and unstable for quite some time now!
|
|
Allow a few specific ones but otherwise this helps ensure that our examples are
squeaky clean!

sidesteps a coherence difficulty where `liballoc` had to prove that
`&str: !Error`, which didn't involve any local types.

comment includes a test that also shows how it can be used.

* Marks `#[stable]` the contents of the `std::convert` module.
* Added methods `PathBuf::as_path`, `OsString::as_os_str`,
`String::as_str`, `Vec::{as_slice, as_mut_slice}`.
* Deprecates `OsStr::from_str` in favor of a new, stable, and more
general `OsStr::new`.
* Adds unstable methods `OsString::from_bytes` and `OsStr::{to_bytes,
to_cstring}` for ergonomic FFI usage.

This commit cleans out a large amount of deprecated APIs from the standard
library and some of the facade crates as well, updating all users in the
compiler and in tests as it goes along.
