2017-05-11Auto merge of #41684 - jethrogb:feature/ntstatus, r=alexcrichtonbors-3/+38
Windows io::Error: also format NTSTATUS error codes `NTSTATUS` errors may be encoded as `HRESULT`, see [[MS-ERREF]](https://msdn.microsoft.com/en-us/library/cc231198.aspx). These error codes can still be formatted using `FormatMessageW` but require some different parameters to be passed in. I wasn't sure if this needed a test and if so, how to test it. Presumably we wouldn't want to make our tests dependent on localization-dependent strings returned from `FormatMessageW`. Users that get an `err: NTSTATUS` will need to do `io::Error::from_raw_os_error(err|0x1000_0000)` (the equivalent of [`HRESULT_FROM_NT`](https://msdn.microsoft.com/en-us/library/ms693780(VS.85).aspx))

2017-05-11Rollup merge of #41192 - zackw:eprintln, r=alexcrichtonCorey Farwell-24/+86
Add `eprint!` and `eprintln!` macros to the prelude. These are exactly the same as `print!` and `println!` except that they write to stderr instead of stdout. Issues #39228 and #40528; previous PR #39229; accepted RFC rust-lang/rfcs#1869; proposed revision to The Book rust-lang/book#615. I have _not_ revised this any since the original submission; I will do that later this week. I wanted to get this PR in place since it's been quite a while since the RFC was merged. Known outstanding review comments: * [x] @steveklabnik requested a new chapter for the unstable version of The Book -- please see if the proposed revisions to the second edition cover it. * [x] @nodakai asked if it were possible to merge the internal methods `_print` and `_eprint` - not completely, since they both refer to different internal globals which we don't want to expose, but I will see if some duplication can be factored out. Please let me know if I missed anything.

[Doc] Improve `thread::spawn` documentation Part of #29378 - Add two examples to `thread::spawn` doumentation that show common uses of threads. - Add a link to `thread::Builder` in the `thread::spawn` documentation for configuring threads. - Add a link to `thread::spawn` in `thread::Builder` in order to avoid documentation duplication. r? @steveklabnik
2017-05-10Rollup merge of #41809 - gamazeps:thread-docs, r=steveklabnikSteve Klabnik-61/+91
[DOC] Improve the thread::park and thread::unpark documentation Part of #29378 . Takes care of the documentation for `park`, `park_duration` and also improves the `unpark` example. - `park should` have its module documentation inlined here, and cleaned up. - `park_timeout` could use links to `park`.

Add more ways to create a PathBuf to docs The best way to do this wasn't in the documentation, and the ways that were there needed some extra text to elaborate. Fixes #40159 /cc @nagisa

2017-05-10Revise the eprint(ln)! feature.Zack Weinberg-58/+37
* Factor out the nigh-identical bodies of `_print` and `_eprint` to a helper function `print_to` (I was sorely tempted to call it `_doprnt`). * Update the issue number for the unstable `eprint` feature. * Add entries to the "unstable book" for `eprint` and `eprint_internal`. * Style corrections to the documentation.

2017-05-10Auto merge of #41815 - Yamakaky:improve-backtrace-bottom, r=alexcrichtonbors-8/+47
Improve cleaning of the bottom of the backtrace Following https://github.com/rust-lang/rust/pull/40264. It only cleans the bottom of the trace (after the main). It handles correctly the normal main, tests, benchmarks and threads. I kept `skipped_before` since it will be used later for the cleaning of the top.

When `RUST_BACKTRACE=1`, remove all frames after `__rust_maybe_catch_panic`. Tested on `main`, threads, tests and benches. Cleaning of the top of the stacktrace is let to a future PR. Fixes #40201 See #41815

2017-05-09Auto merge of #41814 - gamazeps:thread-struct-doc, r=steveklabnikbors-23/+20
[Doc] improve `thread::Thread` and `thread::Builder` documentations Part of #29378 - Adds information about the stack_size when using `Builder`. This might be considered too low level, but I assume that if someone wants to create their own builder instead of using `thread::spawn` they may be interested in that info. - Updates the `thread::Thread` structure doc, mostly by explaining how to get one, the previous example was removed because it was not related to `thread::Thread`, but rather to `thread::Builder::name`. Not much is present there, mostly because this API is not often used (the only method that seems useful is `unpark`, which is documented in #41809).
