This is a pretty trivial change. My eye caught some inconsistent whitespace while perusing compiler errors tonight. Specifically, I changed `//correct` to `// correct`, and got rid of some trailing whitespace that isn't seen in other code snippets.
This commit expands the "supported platforms" section of the book to include
documentation on the tiers that Rust currently has as well as organizing all
supported platforms into these various tiers. Infrastructure improvements over
the next few months are likely to change the location of may of these platforms
over, but for now this should faithfully represent what we've got today!

Yay, markdown isn't standardized and rustbook's parser has subtle incompatibilities with Github's! So in the Github preview you don't see that this list fails to separate from the previous paragraph. I think this should fix it, but I didn't check.
This is a WIP PR for my implementation of drain over the VecDeque data structure supporting ranges. It brings the VecDeque drain implementation in line with Vec's.
Tests haven't been written for the new function yet.
The attributes are copied from the item for which the trait impl is derived
I think now we can close these two issues:
https://github.com/rust-lang/rust/issues/13054 - `allow`, `deny` etc. were already copied, now `stable` and `unstable` are copied as well.
https://github.com/rust-lang/rust/issues/18969 - I'm not sure this is needed, insta-stability were good enough so far, copied stability will be better. Nonetheless, it can be subsumed by some more general mechanism for supplying arbitrary not necessarily stability related attributes (for example `inline`) to derived impls and their methods (I haven't found an open issue for such mechanism).

This is for discoverability. If someone wants to know what `?Sized` means, then
Sized will be the only keyword they can use to search; so even though this is
technically a language matter, it makes sense to document it where it will be
looked for.
This commit splits out the standard library from the current 'rustc' package
into a new 'rust-std' package. This is the basis for the work on easily
packaging compilers that can cross-compile to new targets.
Remove leading newlines; replace lines containing only whitespace with empty lines; replace multiple trailing newlines with a single newline; remove trailing whitespace in lines.
This PR was created semiautomatically.
To augment the didactic effect, made placed the thread::sleep_ms call in the last example, so that there will be time for the other locks to happen; without this, I was unable to observe the deadlock in over 1,000 runs when there was no left-handed philosopher.
I wasn't sure whether `Ordering::Relaxed` meant `Monotonic` or `Unordered`, so I checked the compiler sources and found 206af38e74/src/librustc_trans/trans/intrinsic.rs (L846) which appears conclusive. Adding this answer to the documentation.
Due to the way iterators work, the std::iter module is chock full of
structs that you, humble Rust programmer, will never actually use.
However, they have URLs, and therefore get linked to, because they are
real structs that do exist.
So, rather than just have a tiny sentence about each one of them,
this patch adds links back to the functions and methods on Iterator
which actually create the structs, where helpful documentation already
exists.
`OsString` has these sorts of conversions, while `CString` has been missing them. I'm iffy on `into_string` simply because the return type would be better off as `FromUtf8Error<CString>`, which of course isn't generic 😢
Also should a different/new feature gate be used?
