This adds support in rustdoc to blanket apply crate attributes to all doc tests
for a crate at once. The syntax for doing this is:
#![doc(test(attr(...)))]
Each meta item in `...` will be applied to each doctest as a crate attribute.

All methods listed in "Trait Implementations" now hyperlink to the source trait
instead of themselves, allowing easy browsing of the documentation of a trait
method.
Closes#17476
This ensures that all external traits are run through the same filters that the
rest of the AST goes through, stripping hidden function as necessary.
Closes#13698
Add a new test directory called 'rustdoc' where all files inside are documented
and run against the `htmldocck` script to have assertions about the output.
@mahkoh points out in #15628 that unicode.py does not use
normative data for Grapheme classes. This pr fixes that issue,
and does some minor cleanup of the unicode.py script.
In addition, GC_RegionalIndicator is renamed GC_Regional_Indicator
in order to stay in line with the Unicode class name definitions.
I have updated refs in u_str.rs, and verified that there are no
refs elsewhere in the codebase. However, in principle someone
using the unicode tables for their own purposes might see breakage
from this.
* Fix broken \"module-level documentation\" link on the [`trait Any` docs](http://doc.rust-lang.org/std/any/trait.Any.html) and related broken markup on the [`std::any` docs](http://doc.rust-lang.org/std/any/index.html).
* Remove an outdated or incorrect notice in the `BufRead::lines` docs. There is no such `read_string` function, and `lines` never returns an error.

If we add a `use` line right above `main` and make the right things public,
everything is fine:
However, the use line was actually placed at the top of the file instead. Move
the use line to right above main. That also makes the example more evocative
of cases where the module is defined in a separate file.
Fixes#24030
Of the four code samples with modules in TRPL:
- 2 use `mod test`
- 2 use `mod tests`
We should be consistent here, but which is right? The stdlib is split:
$ grep -r 'mod tests {' src/lib* | wc -l
63
$ grep -r 'mod test {' src/lib* | wc -l
58
Subjectively, I like the plural, but both the language reference and the
style guide recommend the singular. So we'll go with that here, for now.

Because the current style for `code` in rustdoc is to prewrap whitespace, code spans that are hard wrapped in the source documentation are prematurely wrapped when rendered in HTML. [For example][2],
```
/// ...
/// type can be borrowed as multiple different types. In particular, `Vec<T>:
/// Borrow<Vec<T>>` and `Vec<T>: Borrow<[T]>`.
```
renders as
because "`Vec<T>: Borrow<Vec<T>>`" wraps to the next line in the source.
CommonMark 0.18 [[1]] specifies "interior spaces and line endings are collapsed into single spaces" for code spans, which would actually prevent this issue, but hoedown does not currently conform to the
CommonMark spec.
The added span-level callback attempts to adhere to how whitespace is handled as described by CommonMark, fixing the issue of early, unintentional wrapping of code spans in rendered HTML.

The current help string ("space separated list") suggests that `--passes "pass1 pass2"` is expected; the orrect usage is `--passes pass1 --passes pass2`.
This adds the missing methods and turns `str::pattern` in a user facing module, as per RFC.
This also contains some big internal refactorings:
- string iterator pairs are implemented with a central macro to reduce redundancy
- Moved all tests from `coretest::str` into `collectionstest::str` and left a note to prevent the two sets of tests drifting apart further.

Hello!
I've been working towards a libsyntax without panics. See:
http://internals.rust-lang.org/t/changing-libsyntax-to-use-result-instead-of-panic/1670
This patch changes the internals of parser.rs to use Result<> rather than panicing. It keeps the following old-style panicing functions as a facade:
parse_expr, parse_item, parse_pat, parse_arm, parse_ty, parse_stmt
I left these functions because I wasn't sure what to do about the quote_* macros or how many syntax-extensions would break if these and quoting macros returned Result.
The gyst of the rest of the patch is:
- Functions in parse/parser.rs return PResult<> rather than panicing
- Other functions in libsyntax call panic! explicitly if they rely on panicing behaviour.
- I added a macro 'panictry!()' to act as scaffolding for callers while converting panicing functions. (This does the same as 'unwrap()' but is easier to grep for and turn into try!()).
Am I on the right track? I'd quite like to get something merged soon as keeping this rebased in the face of libsyntax changes is a lot of work. Please let me know what changes you'd like to see to make this happen.
Thanks!, Phil

If we find a blanket impl for `Trait` but we're matching on an object `Trait`, prefer the object (I think we could perhaps go either way, but this seems safer). Also give a nice error for attempts to manually `impl Trait for Trait`, since they will be ineffectual.
This fixes the problems around ambiguity ICEs relating to `Any` and `MarkerTrait` that were cropping up all over the place. There may still be similar ICEs reported in #21756 that this PR does not address.
