* Include tip given by Leo Testard in mailing list about labeled `break`
and `continue`:

* cross-reference named lifetimes in tutorial -> lifetimes guide
* Broke named lifetimes section into two sub-sections.
* Added mention of `'static` lifetime.
This is not sufficient for finding the library directory for binary
installs, but it does make the build more complex by requiring
env vars be set to build rustc.
The previous dependency calculation was based on an arbitrary set of asterisks
at an arbitrary depth, but using the recursive version should be much more
robust in figuring out what's dependent.
Closes#13118

This moves derived impls to the bottom of the list, separate from the rest,
and collapses default methods that aren't overridden into an expandible
accordion.
Apparently we had forgotten to do this for freebsd, causing possible problems
on FreeBSD 10. The discussion in #12324 has some more details about how it's
missing.
The libuv fs wrappers are very thin wrappers around the syscalls they correspond
to, and a notable worrisome case is the write syscall. This syscall is not
guaranteed to write the entire buffer provided, so we may have to continue
calling uv_fs_write if a short write occurs.
Closes#13130
It was possible to borrow unsafe static items in static initializers.
This patch implements a small `Visitor` that walks static initializer's
expressions and checks borrows aliasability.
Fixes#13005
cc @nikomatsakis r?
Several things here:
* Cleanup
* Fix build targets for building .pkg so that it works and works for all hosts
* Adds support for nightly artifacts
* Put docs in a location suitable for upload to s3 during 'make dist'
* Add coverage of unix binary installers to 'distcheck'
* Fix 'distcheck'
* Change 'dist' to build source tarballs, binary tarballs and OS X packages
This commit contains an implementation of synchronous, bounded channels for
Rust. This is an implementation of the proposal made last January [1]. These
channels are built on mutexes, and currently focus on a working implementation
rather than speed. Receivers for sync channels have select() implemented for
them, but there is currently no implementation of select() for sync senders.
Rust will continue to provide both synchronous and asynchronous channels as part
of the standard distribution, there is no intent to remove asynchronous
channels. This flavor of channels is meant to provide an alternative to
asynchronous channels because like green tasks, asynchronous channels are not
appropriate for all situations.

* Remove clone-ability from all primitives. All shared state will now come
from the usage of the primitives being shared, not the primitives being
inherently shareable. This allows for fewer allocations for stack-allocated
primitives.
* Add `Mutex<T>` and `RWLock<T>` which are stack-allocated primitives for purely
wrapping a piece of data
* Remove `RWArc<T>` in favor of `Arc<RWLock<T>>`
* Remove `MutexArc<T>` in favor of `Arc<Mutex<T>>`
* Shuffle around where things are located
* The `arc` module now only contains `Arc`
* A new `lock` module contains `Mutex`, `RWLock`, and `Barrier`
* A new `raw` module contains the primitive implementations of `Semaphore`,
`Mutex`, and `RWLock`
* The Deref/DerefMut trait was implemented where appropriate
* `CowArc` was removed, the functionality is now part of `Arc` and is tagged
with `#[experimental]`.
* The crate now has #[deny(missing_doc)]
* `Arc` now supports weak pointers
This is not a large-scale rewrite of the functionality contained within the
`sync` crate, but rather a shuffling of who does what an a thinner hierarchy of
ownership to allow for better composability.
This removes the now-outdated MutexArc and RWArc types. These are superseded by
Arc<Mutex<T>> and Arc<RWLock<T>>. The only remaining arc is the one true Arc.
Additionally, the arc now has weak pointers implemented for it to assist in
breaking cycles.
This commit brings the arc api up to parity with the sibling Rc api, making them
nearly interchangeable for inter and intra task communication.
The OSX bots have been deadlocking recently in the rustdoc tests. I have only
been able to rarely reproduce the deadlock on my local setup. When reproduced,
it looks like the child process is spinning on the malloc mutex, which I
presume is locked with no other threads to unlock it.
I'm not convinced that this is what's happening, because OSX should protect
against this with pthread_atfork by default. Regardless, running as little code
as possible in the child after fork() is normally a good idea anyway, so this
commit moves all allocation to the parent process to run before the child
executes.
After running 6k iterations of rustdoc tests, this deadlocked twice before, and
after 20k iterations afterwards, it never deadlocked. I draw the conclusion that
this is either sweeping the bug under the rug, or it did indeed fix the
underlying problem.
