New standards have arisen in recent months, mostly for the use of
rustpkg, but the main Rust codebase has not been altered to match these
new specifications. This changeset rectifies most of these issues.
- Renamed the crate source files `src/libX/X.rs` to `lib.rs`, for
consistency with current styles; this affects extra, rustc, rustdoc,
rustpkg, rustuv, std, syntax.
- Renamed `X/X.rs` to `X/mod.rs,` as is now recommended style, for
`std::num` and `std::terminfo`.
- Shifted `src/libstd/str/ascii.rs` out of the otherwise unused `str`
directory, to be consistent with its import path of `std::ascii`;
libstd is flat at present so it's more appropriate thus.
While this removes some `#[path = "..."]` directives, it does not remove
all of them, and leaves certain other inconsistencies, such as `std::u8`
et al. which are actually stored in `src/libstd/num/` (one subdirectory
down). No quorum has been reached on this issue, so I felt it best to
leave them all alone at present. #9208 deals with the possibility of
making libstd more hierarchical (such as changing the crate to match the
current filesystem structure, which would make the module path
`std::num::u8`).
There is one thing remaining in which this repository is not
rustpkg-compliant: rustpkg would have `src/std/` et al. rather than
`src/libstd/` et al. I have not endeavoured to change that at this point
as it would guarantee prompt bitrot and confusion. A change of that
magnitude needs to be discussed first.

Cleaned up the source in a few places
Renamed `map_move` to `map`, removed other `map` methods
Added `as_ref` and `as_mut` adapters to `Result`
Added `fmt::Default` impl

- `begin_unwind` is now generic over any `T: Any + Send`.
- Every value you fail with gets boxed as an `~Any`.
- Because of implementation details, `&'static str` and `~str` are still
handled specially behind the scenes.
- Changed the big macro source string in libsyntax to a raw string
literal, and enabled doc comments there.

There are a few reasons that this is a desirable move to take:
1. Proof of concept that a third party event loop is possible
2. Clear separation of responsibility between rt::io and the uv-backend
3. Enforce in the future that the event loop is "pluggable" and replacable
Here's a quick summary of the points of this pull request which make this
possible:
* Two new lang items were introduced: event_loop, and event_loop_factory.
The idea of a "factory" is to define a function which can be called with no
arguments and will return the new event loop as a trait object. This factory
is emitted to the crate map when building an executable. The factory doesn't
have to exist, and when it doesn't then an empty slot is in the crate map and
a basic event loop with no I/O support is provided to the runtime.
* When building an executable, then the rustuv crate will be linked by default
(providing a default implementation of the event loop) via a similar method to
injecting a dependency on libstd. This is currently the only location where
the rustuv crate is ever linked.
* There is a new #[no_uv] attribute (implied by #[no_std]) which denies
implicitly linking to rustuv by default
Closes #5019

Some code cleanup, sorting of import blocks
Removed std::unstable::UnsafeArc's use of Either
Added run-fail tests for the new FailWithCause impls
Changed future_result and try to return Result<(), ~Any>.
- Internally, there is an enum of possible fail messages passend around.
- In case of linked failure or a string message, the ~Any gets
lazyly allocated in future_results recv method.
- For that, future result now returns a wrapper around a Port.
- Moved and renamed task::TaskResult into rt::task::UnwindResult
and made it an internal enum.
- Introduced a replacement typedef `type TaskResult = Result<(), ~Any>`.

I've left out a way to construct from a `Send` type until #9509 is resolved. I am confident that this interface can remain backwards compatible though, assuming we name the `Pointer` trait method `borrow`.
When there is a way to convert from `Send` (`from_send`), a future RAII-based `Mut` type can be used with this to implemented a mutable reference-counted pointer. For now, I've left around the `RcMut` type but it may drastically change or be removed.

This change was waiting for privacy to get sorted out, which should be true now
that #8215 has landed.

The general idea of hyperlinking between crates is that it should require as
little configuration as possible, if any at all. In this vein, there are two
separate ways to generate hyperlinks between crates:
1. When you're generating documentation for a crate 'foo' into folder 'doc',
then if foo's external crate dependencies already have documented in the
folder 'doc', then hyperlinks will be generated. This will work because all
documentation is in the same folder, allowing links to work seamlessly both
on the web and on the local filesystem browser.
The rationale for this use case is a package with multiple libraries/crates
that all want to link to one another, and you don't want to have to deal with
going to the web. In theory this could be extended to have a RUST_PATH-style
searching situtation, but I'm not sure that it would work seamlessly on the
web as it does on the local filesystem, so I'm not attempting to explore this
case in this pull request. I believe to fully realize this potential rustdoc
would have to be acting as a server instead of a static site generator.
2. One of foo's external dependencies has a #[doc(html_root_url = "...")]
attribute. This means that all hyperlinks to the dependency will be rooted at
this url.
This use case encompasses all packages using libstd/libextra. These two
crates now have this attribute encoded (currently at the /doc/master url) and
will be read by anything which has a dependency on libstd/libextra. This
should also work for arbitrary crates in the wild that have online
documentation. I don't like how the version is hard-wired into the url, but I
think that this may be a case-by-case thing which doesn't end up being too
bad in the long run.
Closes #9539

It is simply defined as `f64` across every platform right now.
A use case hasn't been presented for a `float` type defined as the
highest precision floating point type implemented in hardware on the
platform. Performance-wise, using the smallest precision correct for the
use case greatly saves on cache space and allows for fitting more
numbers into SSE/AVX registers.
If there was a use case, this could be implemented as simply a type
alias or a struct thanks to `#[cfg(...)]`.
Closes #6592

This lifts various restrictions on the runtime, for example the character limit
when logging a message. Right now the old debug!-style macros still involve
allocating (because they use fmt! syntax), but the new debug2! macros don't
involve allocating at all (unless the formatter for a type requires allocation.

This large commit implements and `html` output option for rustdoc_ng. The
executable has been altered to be invoked as "rustdoc_ng html <crate>" and
it will dump everything into the local "doc" directory. JSON can still be
generated by changing 'html' to 'json'.
This also fixes a number of bugs in rustdoc_ng relating to comment stripping,
along with some other various issues that I found along the way.
The `make doc` command has been altered to generate the new documentation into
the `doc/ng/$(CRATE)` directories.

A SendStr is a string that can hold either a ~str or a &'static str.
This can be useful as an optimization when an allocation is sometimes needed but the common case is statically known.
Possible use cases include Maps with both static and owned keys, or propagating error messages across task boundaries.
SendStr implements most basic traits in a way that hides the fact that it is an enum; in particular things like order and equality are only determined by the content of the wrapped strings.
Replaced std::rt:logging::SendableString with SendStr
Added tests for using an SendStr as key in Hash- and Treemaps

Also redefine all of the standard logging macros to use more rust code instead
of custom LLVM translation code. This makes them a bit easier to understand, but
also more flexibile for future types of logging.
Additionally, this commit removes the LogType language item in preparation for
changing how logging is performed.

The trait will keep the `Iterator` naming, but a more concise module
name makes using the free functions less verbose. The module will define
iterables in addition to iterators, as it deals with iteration in
general.

At the same time, this updates the TyVisitor to use a mutable self because it's
probably going to be mutating state as it goes along anyway.

Moves the Times trait to num while the question of whether it should
exist at all gets hashed out as a completely separate question.

This PR fixes #7235 and #3371, which removes trailing nulls from `str` types. Instead, it replaces the creation of c strings with a new type, `std::c_str::CString`, which wraps a malloced byte array, and respects:
* No interior nulls
* Ends with a trailing null

If the TLS key is 0-sized, then the linux linker is apparently smart enough to
put everything at the same pointer. OSX on the other hand, will reserve some
space for all of them. To get around this, the TLS key now actuall consumes
space to ensure that it gets a unique pointer
