[breaking change]
I'm not sure if those renames are ok. [TokenType::Tt* to TokenType::*](https://github.com/rust-lang/rust/pull/29582) was obvious, but for all those Item-enums it's less obvious to me what the right way forward is due to the underscore.
On distros that use i486 or i586 in their CHOST, Rust will fail to build
because it is not handling i486 or i586 like i686 is handled. This
changes the match to do work for all instances of i?86 instead of just
i686. The Yocto Project still uses i586 as a target.

While these points are true, we're not going for 100% accuracy here,
this is introductory material. Changing these things would be more
confusing, but it is important to note that we're presenting an
abstraction here.

under openbsd, the library path of libstdc++ need to be explicit (due
to the fact the default linker `cc` is gcc-4.2, and not gcc-4.9).
but when a recent LLVM is installed, rustc compilation pikes the bad
LLVM version (which live in /usr/local/lib, which is same directory of
libestdc++.so for gcc-4.9).
this patch move the libstdc++ path from RUST_FLAGS_<target> to special
variable, and use it *after* LLVM_LIBDIR_RUSTFLAGS_<target> in
arguments.

Otherwise, the iterator and the functions for getting specific
environment variables might disagree, for environments like
FOOBAR
Variable names starting with equals sign are OK:
glibc only interprets equals signs not in the first position as
separators between variable name and variable value. Instead of skipping
them entirely, a leading equals sign is interpreted to be part of the
variable name.

The command-line error message for E0432 does mention the possibility of missing the `extern crate` declaration, but the detailed error message for it doesn't.
Fixes#29517.
I noticed the nomicon was not listed!
I also removed links to racer and rustfmt since they were not *doc-specific* links, just links to tools, as well as pointed the cargo link directly at the docs.
Removed all the community stuff. There are lots of other places to find this now, including the website.
With pending website changes this page will continue to be pared back, reflecting only what's in-tree, not general Rust docs.

Sometimes when writing generic code you want to abstract over
owning/pointer type so that calling code isn't restricted by one
concrete owning/pointer type. This commit makes possible such code:
```rust
fn i_will_work_with_arc<T: Into<Arc<MyTy>>>(t: T) {
let the_arc = t.into();
// Do something
}
i_will_work_with_arc(MyTy::new());
i_will_work_with_arc(Box::new(MyTy::new()));
let arc_that_i_already_have = Arc::new(MyTy::new());
i_will_work_with_arc(arc_that_i_already_have);
```
Please note that this patch doesn't work with DSTs.
Also to mention, I made those impls stable, and I don't know whether they should be actually stable from the beginning. Please tell me if this should be feature-gated.

insert() returns bool, but it was wrongly stated that if the set had the
key already present, that key would be returned (this was probably
copied from the HashMap docs). Also remove a reference to the
module-level documentation, which doesn't make sense as it doesn't give
any more context.

This should get `--libdir` working as well as it was a couple of weeks ago. (That is, it still rewrites paths incorrectly but it no longer fails during `make install`.)
Fixesgentoo/gentoo-rust#28 and gentoo/gentoo-rust#29.

This is to handle the case where CFG_LIBDIR is not a direct child of
CFG_PREFIX (in other words, where CFG_LIBDIR_RELATIVE has more than
one component).
f357d55 caused a regression by retrieving item names from metadata, while previously using the last element of its absolute path (which in the case of a root module is the prefixed crate name since the stored path in metadata is empty)
