The style `[name][]` does not work with Pandoc, whereas `[name]` does.
I hope hoedown accepts this as well.

This commit does some refactoring to make almost all of the `std::rt` private.
Specifically, the following items are no longer part of its API:
* DEFAULT_ERROR_CODE
* backtrace
* unwind
* args
* at_exit
* cleanup
* heap (this is just alloc::heap)
* min_stack
* util
The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is
an entry point for the `panic!` macro via the `begin_unwind` and
`begin_unwind_fmt` reexports.

This was @steveklabnik's idea. Thanks @BurntSushi for the awesome blog post!

The phrase 'academic research' rubs me the wrong way. I have some concern about the role of this page and think it could be expanded to more than just academic papers and cleaned up a lot.

I took a stab at fixing #28064. Not sure if this all-features-in-one-example approach is the right one. Also I completely made up the terms "star globbing" and "brace expansion globbing" -- they are just called "glob-like syntax" in the reference.

Follow-up fix for PR #28283.

Thanks Eric, reported via email

The link address is defined below the paragraph so no need to have it inline.

In the last code snippet on the following page there is a bug in the
implementation of Vec::drain().
https://doc.rust-lang.org/nightly/nomicon/vec-drain.html
```rust
pub fn drain(&mut self) -> Drain<T> {
// Oops, setting it to 0 while we still need the old value!
self.len = 0;
unsafe {
Drain {
// len is used to create a &[T] from &self here,
// so we end up always creating an empty slice.
iter: RawValIter::new(&self),
vec: PhantomData,
}
}
}
```
A simple test to verify that Drain is broken can be found here:
https://play.rust-lang.org/?gist=30f579565e4bbf4836ce&version=nightly
And here's one with a fixed implementation:
https://play.rust-lang.org/?gist=2ec0c1a6dcf5defd7a53&version=nightly

This is a docs change suggested in #28196.

extern_block should be extern_block_item.
extern_block_item is `extern { bunch of fns }`, extern_block is just `bunch of fns`

Also, add missing comma
