Any macro tagged with #[macro_export] will be showed in the documentation for
that module. This also documents all the existing macros inside of std::macros.

Iterators! Use them (in `is_utf16`), create them (in `utf16_items`).
Handle errors gracefully (`from_utf16_lossy`) and `from_utf16` returning `Option<~str>` instead of failing.
Add a pile of tests.
Many of the functions interacting with Windows APIs allocate a vector of
0's and do not retrieve a length directly from the API call, and so need
to be sure to remove the unmodified junk at the end of the vector.
With Rc no longer trying to statically prevent cycles (and thus no
longer using the Freeze bound), it seems appropriate to remove that
restriction from MutexArc as well.
Closes#9251.
The details can be found in the comments I added to the test, but the gist of it
is that capturing output injects rescheduling a green task on failure, which
wasn't desired for the test in question.

See the commit messages for more details, but this makes `std::str::is_utf8` slightly faster and 100% non-`unsafe` and uses a similar thing to make the first scan of `from_utf8_lossy` 100% safe & faster.
This uses a vector iterator to avoid the necessity for unsafe indexing,
and makes this function slightly faster. Unfortunately #11751 means that
the iterator comes with repeated `null` checks which means the
pure-ASCII case still has room for significant improvement (and the
other cases too, but it's most significant for just ASCII).
Before:
is_utf8_100_ascii ... bench: 143 ns/iter (+/- 6)
is_utf8_100_multibyte ... bench: 134 ns/iter (+/- 4)
After:
is_utf8_100_ascii ... bench: 123 ns/iter (+/- 4)
is_utf8_100_multibyte ... bench: 115 ns/iter (+/- 5)
There's a few parts to this PR
* Implement unix pipes in libnative for unix platforms (thanks @Geal!)
* Implement named pipes in libnative for windows (terrible, terrible code)
* Remove `#[cfg(unix)]` from `mod unix` in `std::io::net`. This is a terrible name for what it is, but that's the topic of #12093.
The windows implementation was significantly more complicated than I thought it would be, but it seems to be passing all the tests. now.
Closes#11201
Extends the license and formatting check to `*.js` files in `src/doc` and `*.sh`, `*.pl`, `*.c`, and `*.h` files in `src/etc`. As best as I could tell, these files should be covered under the Rust project license.
cc @brson: Do any other scripts need a license? I'd like to double-check that this PR closes#4534.
Delete all the documentation from std::task that references linked
failure.
Tweak TaskBuilder to be more builder-like. `.name()` is now `.named()` and
`.add_wrapper()` is now `.with_wrapper()`. Remove `.watched()` and
`.unwatched()` as they didn't actually do anything.
Closes#6399.

This deadlock was caused when the channel was closed at just the right time, so
the extra `self.cnt.fetch_add` actually should have preserved the DISCONNECTED
state of the channel. by modifying this the channel entered a state such that
the port would never succeed in dropping.
This also moves the increment of self.steals until after the MAX_STEALS block.
The reason for this is that in 'fn recv()' the steals variable is decremented
immediately after the try_recv(), which could in theory set steals to -1 if it
was previously set to 0 in try_recv().

This is inspired by the [function naming in the Julia standard library](http://docs.julialang.org/en/release-0.2/stdlib/base/#Base.count_ones). It seems like a more self-explanatory name, and is more consistent with the accompanying methods, `leading_zeros` and `trailing_zeros`.
This replaces the iterator with one that handles lone surrogates
gracefully and uses that to implement `from_utf16_lossy` which replaces
invalid `u16`s with U+FFFD.
Work toward #9876.
This adds `prepare.mk`, which is simply a more heavily-parameterized `install.mk`, then uses `prepare` to implement both `install` and the windows installer (`dist`). Smoke tested on both Linux and Windows.

longer using the Freeze bound), it seems appropriate to remove that
