On DragonFly pthread_{mutex,rwlock,condvar}_destroy() returns EINVAL
when called on a pthread_{mutex,rwlock,condvar}_t that was just
initialized via PTHREAD_{MUTEX,RWLOCK,CONDVAR}_INITIALIZER and not used
in the meantime or initialized via pthread_{mutex,rwlock,condvar}_init().
Change the code to treat a return value of EINVAL on DragonFly as success.
This gets rid of the 'experimental' level, removes the non-staged_api
case (i.e. stability levels for out-of-tree crates), and lets the
staged_api attributes use 'unstable' and 'deprecated' lints.
This makes the transition period to the full feature staging design
a bit nicer.
An updated version of https://github.com/rust-lang/rust/pull/19461
This version vendors aturon/rust-book@731f7bf and builds it when building the docs. This is almost great, except my `make`-foo is poor, so I have my own personal paths in `mk/docs.mk`. How should I best get around that?

This pulls all of our long-form documentation into a single document,
nicknamed "the book" and formally titled "The Rust Programming
Language."
A few things motivated this change:
* People knew of The Guide, but not the individual Guides. This merges
them together, helping discoverability.
* You can get all of Rust's longform documentation in one place, which
is nice.
* We now have rustbook in-tree, which can generate this kind of
documentation. While its style is basic, the general idea is much
better: a table of contents on the left-hand side.
* Rather than a almost 10,000-line guide.md, there are now smaller files
per section.
`rustc something.rs -L folder_with_plugin_dylib/ -Z extra-plugins=foo` works via this
My way of testing this is by cloning https://github.com/Manishearth/rust-clippy, `cargo build`ing it, and then running `rustc examples/box_vec.rs -L target/ -Z extra-plugins=rust_clippy` after editing out the `exern crate rust_clippy` from `box_vec.rs`

fixes#15446
deref that is associated with an overloaded index, we should not
consult the method lookup table. This deref is *always* a deref of an
`&T` and hence is never overloaded (and is also not present in the
tables; it has no "id" or other associated key).
This gets rid of the 'experimental' level, removes the non-staged_api
case (i.e. stability levels for out-of-tree crates), and lets the
staged_api attributes use 'unstable' and 'deprecated' lints.
This makes the transition period to the full feature staging design
a bit nicer.
