We've got a freshly minted beta compiler, let's update to use that on nightly!
This has a few other changes associated with it as well
* A bump to the rustc version number (to 1.19.0)
* Movement of the `cargo` and `rls` submodules to their "proper" location in
`src/tools/{cargo,rls}`. Now that Cargo workspaces support the `exclude`
option this can work.
* Updates of the `cargo` and `rls` submodules to their master branches.
* Tweak to the `src/stage0.txt` format to be more amenable for Cargo version
numbers. On the beta channel Cargo will bootstrap from a different version
than rustc (e.g. the version numbers are different), so we need different
configuration for this.
* Addition of `dev` as a readable key in the `src/stage0.txt` format. If present
then stage0 compilers are downloaded from `dev-static.rust-lang.org` instead
of `static.rust-lang.org`. This is added to accomodate our updated release
process with Travis and AppVeyor.
Adding links and examples for various mspc pages #29377
Adding links and copying examples for the various Iterators; adding some extra stuff to `Sender`/`SyncSender`/`Receiver`.
Address platform-specific behavior in TcpStream::shutdown
Fixes#25164
r? @rust-lang/libs from the GitHub thread, it seems like documenting this behavior is okay, but I want to make sure that's what you want.
Support AddressSanitizer and ThreadSanitizer on x86_64-apple-darwin
[ASan](https://clang.llvm.org/docs/AddressSanitizer.html#supported-platforms) and [TSan](https://clang.llvm.org/docs/ThreadSanitizer.html#supported-platforms) are supported on macOS, and this commit enables their support.
The sanitizers are always built as `*.dylib` on Apple platforms, so they cannot be statically linked into the corresponding `rustc_?san.rlib`. The dylibs are directly copied to `lib/rustlib/x86_64-apple-darwin/lib/` instead.
Note, although Xcode also ships with their own copies of ASan/TSan dylibs, we cannot use them due to version mismatch.
----
~~There is a caveat: the sanitizer libraries are linked as `@rpath/` (due to https://reviews.llvm.org/D6018), so the user needs to additionally pass `-C rpath`:~~
**Edit:** Passing rpath is now automatic.
Specify behavior of `write_all` for `ErrorKind::Interrupted` errors
Also spell out that read and write operations should be retried on
`ErrorKind::Interrupted` errors.
Fixes#38494.

Otherwise there will be a runtime error:
dyld: Library not loaded: @rpath/libclang_rt.asan_osx_dynamic.dylib
Referenced from: /path/to/executable
Reason: image not found
Abort trap: 6
The next commit includes a temporary change in compiler to force the linker
to emit a usable @rpath.
Expanded docs and examples for PathBuf::file_name and friends
This addresses some common surprises when `PathBuf::set_file_name` is called on the path of a directory rather than a file.
r? @steveklabnik
Update `Child` docs to not have a note section
In #29370 it's noted that for "the Note shouldn't be one, and should come before
the examples." This commit changes the positioning of the section and removes
wording that said take note in order for it to flow better with the surrounding
text and it's new position.
Override ToOwned::clone_into for Path and OsStr
The only non-overridden one remaining is the CStr impl, which cannot
be optimized as doing so would break CString's second invariant.
Follow-up to 7ec27ae (PR #41009).
r? @alexcrichton
Improve std::path docs
Fixes#29368.
This PR contains a pretty significant redistribution of some of the module docs to more appropriate places, as well as general expansion, clarification, and additional examples.

std: Back out backtrace pruning logic
It was discovered #40264 that this backtrace pruning logic is a little too
aggressive, so while we figure how out to handle #40264 this commit backs out
the changes to prune frames. Note that other cosmetic changes, such as better
path printing and such remain.
Improve Process::spawn with piped stdio on Redox
- Adds `dup2`, and uses it for stdio piping
- Removes `O_CLOEXEC` from piped stdio, as `dup` on Redox does not disable O_CLOEXEC

Part of #29368.
* Added a new summary paragraph about std::path's parsing facilities
* Slightly exanded `Component`'s docs
* removed the now redundant section on component types from the module docs
* moved the section on path normalization during parsing to the docs on
`Path::components`
* Clarified difference between `Prefix` and `PrefixComponent` in their
respecive summary sentences
