This change extends the pkgid attribute to allow of explicit crate names, instead of always inferring them based on the path. This means that if your GitHub repo is called `rust-foo`, you can have your pkgid set your library name to `foo`. You'd do this with a pkgid attribute like `github.com/somewhere/rust-foo#foo:1.0`.
This is half of the fix for #10922.
rustdoc:
- fix search-bar layout
doc: CSS:
- switch to native pandoc toc depth
- rm some dead code
- clamp width to be readable (we're not Wikipedia!)
- don't background-color titles, it's bloating
- make syntax-highlighting colors inline with rust-lang.org
- space indents

The section on closure types was missing, so I added one. I'm new to Rust, so there are probably important things to say about closure types that I'm missing here.
I tested the example with the latest Rust nightly.
This includes documentation for all the previous changes done to linking
in #10582. Additionally, this brings the list of feature-gates up-to-date with
the currently recognized list of features.
This commit implements the support necessary for generating both intermediate
and result static rust libraries. This is an implementation of my thoughts in
https://mail.mozilla.org/pipermail/rust-dev/2013-November/006686.html.
When compiling a library, we still retain the "lib" option, although now there
are "rlib", "staticlib", and "dylib" as options for crate_type (and these are
stackable). The idea of "lib" is to generate the "compiler default" instead of
having too choose (although all are interchangeable). For now I have left the
"complier default" to be a dynamic library for size reasons.
Of the rust libraries, lib{std,extra,rustuv} will bootstrap with an
rlib/dylib pair, but lib{rustc,syntax,rustdoc,rustpkg} will only be built as a
dynamic object. I chose this for size reasons, but also because you're probably
not going to be embedding the rustc compiler anywhere any time soon.
Other than the options outlined above, there are a few defaults/preferences that
are now opinionated in the compiler:
* If both a .dylib and .rlib are found for a rust library, the compiler will
prefer the .rlib variant. This is overridable via the -Z prefer-dynamic option
* If generating a "lib", the compiler will generate a dynamic library. This is
overridable by explicitly saying what flavor you'd like (rlib, staticlib,
dylib).
* If no options are passed to the command line, and no crate_type is found in
the destination crate, then an executable is generated
With this change, you can successfully build a rust program with 0 dynamic
dependencies on rust libraries. There is still a dynamic dependency on
librustrt, but I plan on removing that in a subsequent commit.
This change includes no tests just yet. Our current testing
infrastructure/harnesses aren't very amenable to doing flavorful things with
linking, so I'm planning on adding a new mode of testing which I believe belongs
as a separate commit.
Closes#552
Previously, `//// foo` and `/*** foo ***/` were accepted as doc comments. This
changes that, so that only `/// foo` and `/** foo ***/` are accepted. This
confuses many newcomers and it seems weird.
Also update the manual for these changes, and modernify the EBNF for comments.
Closes#10638
The reasons for doing this are:
* The model on which linked failure is based is inherently complex
* The implementation is also very complex, and there are few remaining who
fully understand the implementation
* There are existing race conditions in the core context switching function of
the scheduler, and possibly others.
* It's unclear whether this model of linked failure maps well to a 1:1 threading
model
Linked failure is often a desired aspect of tasks, but we would like to take a
much more conservative approach in re-implementing linked failure if at all.

- Cause `0` to be considered a valid integer literal (it is).
- Add octal literals (missed from #10243).
I have *not* modified doc/po/rust.md.pot or doc/po/ja/rust.md.po at all;
they already seem to be out of date so it's easier to ignore them for
myself. I can update them if desired, of course.
This extension can be used to concatenate string literals at compile time. C has
this useful ability when placing string literals lexically next to one another,
but this needs to be handled at the syntax extension level to recursively expand
macros.
The major use case for this is something like:
macro_rules! mylog( ($fmt:expr $($arg:tt)*) => {
error2!(concat!(file!(), ":", line!(), " - ", $fmt) $($arg)*);
})
Where the mylog macro will automatically prepend the filename/line number to the
beginning of every log message.
Previously an ExprLit was created *per byte* causing a huge increase in memory
bloat. This adds a new `lit_binary` to contain a literal of binary data, which
is currently only used by the include_bin! syntax extension. This massively
speeds up compilation times of the shootout-k-nucleotide-pipes test
before:
time: 469s
memory: 6GB
assertion failure in LLVM (section too large)
after:
time: 2.50s
memory: 124MB
Closes#2598

This removes the warning "Note" about visibility not being fully defined, as it
should now be considered fully defined with further bugs being considered just
bugs in the implementation.
A few features are now hidden behind various #[feature(...)] directives. These
include struct-like enum variants, glob imports, and macro_rules! invocations.
