As of cc6ec8df, the Owned closures example uses println! instead of
debug!, making a note about seeing debug seem out-of-place in this
section.
Since debug! is not used elsewhere in the tutorial, remove the note

Hello,
With the latest version of Rust, calling to the function [`std::io::standard_error()`](http://static.rust-lang.org/doc/master/std/io/fn.standard_error.html) succeeds only if the value of the argument is `EndOfFile`, `IoUnavailable` or `InvalidInput`. If the function is called with another value as argument, it fails without message.
Here is a piece of code that reproduces the problem:
```rust
use std::io::{standard_error,EndOfFile,FileNotFound,PermissionDenied};
fn main() {
println!("Error 1: {}", standard_error(EndOfFile)); // does not fail
println!("Error 2: {}", standard_error(FileNotFound)); // fails
println!("Error 3: {}", standard_error(PermissionDenied)); //fails
}
```
This was because the `IoErrorKind` passed as argument wasn't matched against all the possible values.
I added the missing branches in the `match` statement inside the function, and i removed the call to the `fail!()` macro. I rebuilt the crate with the latest `rustc` version and it seems to works.

Just modified the documentation for parse_bytes to make it more clear how the bytes were parsed (big endian) and to show an example of what it returned. I also added documentation for the to_str_bytes which previously had no documentation (besides one stackoverflow post).
I filed bugs #13734 and #13759 recently, and then realized I could probably fix them myself. This does exactly that, with a couple additional modifications and additions to the test-suite to pick up on that.
I've never done this before, so please feel free to tell me all the things I'm doing wrong or could be doing better.
It reflected the obsolete syntax `use a, b, c;` and did not make past the parser (though it was a non-fatal error so we can continue). This legacy affected many portions of rustc and rustdoc as well, so this PR cleans them up altogether.
As a side effect of cleanup, we now have `SCHEMA_VERSION` in `rustdoc::clean` (instead of the crate root), so it has a better chance to be updated when `rustdoc::clean` gets updated.
This addresses the ICE from #13763, but it does not allow the test to compile,
due to #13768. An alternate test was checked in in the meantime.
Closes#13763

Before, tests for dynamic regexes ran during stage1 and tests for
native regexes ran during stage2. But the buildbots don't test stage1,
so now both dynamic and native tests are run during stage2.
Closes#13740.
Clarifies the interaction of `is_dir`, `is_file` and `exists` with
symbolic links. Adds a convenience `lstat` function alongside of
`stat`. Removes references to conditions.
Closes issue #12583.

Follow-up on issue #13297 and PR #13710. Instead of following the (confusing) C/C++ approach
of using `MIN_VALUE` for the smallest *positive* number, we introduce `MIN_POS_VALUE` (and
in the Float trait, `min_pos_value`) to represent this number.
This patch also removes a few remaining redundantly-defined constants that were missed last
time around.
It didn't work because it tried to call itself but symbols are not
exported as default in executables.
Note that `fun5` is not internal anymore since it is in library.
Second commit removes/updates some old tests.

Implements [RFC 7](https://github.com/rust-lang/rfcs/blob/master/active/0007-regexps.md) and will hopefully resolve#3591. The crate is marked as experimental. It includes a syntax extension for compiling regexps to native Rust code.
Embeds and passes the `basic`, `nullsubexpr` and `repetition` tests from [Glenn Fowler's (slightly modified by Russ Cox for leftmost-first semantics) testregex test suite](http://www2.research.att.com/~astopen/testregex/testregex.html). I've also hand written a plethora of other tests that exercise Unicode support, the parser, public API, etc. Also includes a `regex-dna` benchmark for the shootout.
I know the addition looks huge at first, but consider these things:
1. More than half the number of lines is dedicated to Unicode character classes.
2. Of the ~4,500 lines remaining, 1,225 of them are comments.
3. Another ~800 are tests.
4. That leaves 2500 lines for the meat. The parser is ~850 of them. The public API, compiler, dynamic VM and code generator (for `regexp!`) make up the rest.
I decided to put architecture constants in another mod. They are not used, so a part of me is thinking of just getting rid of them altogether. The rest should be similar to what @brson wants.
Fixes#13536
