extern crate foobar as foo;

Implements remaining part of RFC #47.
Addresses issue #16461.

Removed link_attrs from rust.md, they don't appear to be supported by
the parser.

Changed all the tests to use the new extern crate syntax

Change pretty printer to use 'as' syntax
doc: remove misleading/confusing info

We have to specify the module and the function name in the example where
the module shares a crate with the executable as well, so remove the
redundant (and potentially confusing) mention.
librustc: Restrict transmute intrinsicck to just rust-intrinsic fn's.
Add tests to make sure intrinsicck doesn't apply to non-intrinsic fn's.
Clarify what tx and rx mean

Add a short explanation of what tx and rx mean in terms of channels.
rustdoc: Don't assume that a doc attribute was sugared: Fixes #15976

As of 8876ce44, `is_sugared_doc` is encoded in metadata, so there is no
need to assume that doc attributes came from sugared comments.
Use cargo run in more places
auto merge of #16689 : wickerwaka/rust/crate-as, r=pcwalton

For review. Not sure about the link_attrs stuff. Will work on converting all the tests.

This question comes up relatively frequently on IRC - "what do tx and rx mean?". This change adds a short explanation.

Remove invalid test -- this test reads freed memory, from what I can tell
auto merge of #16797 : nikomatsakis/rust/remove-invalid-spsc_queue-test, r=alexcrichton

This test seems to read freed memory -- the peeked variable points into the queue, but then the pop operation removes the node from the queue and moves the enclosing `T` elsewhere, invalidating the `peeked` pointer.

Fix lies in the concurrency guide.

This cleans up blatant lies in the concurrency guide, and modernizes it
a bit. There's a lot more to do, but until I get to it, let's make it a
little bit better.

This cleans up blatant lies in the concurrency guide, and modernizes it
a bit. There's a lot more to do, but until I get to it, let's make it a
little bit better.
Fix whitespace and missing parentheses.
