Visit type parameter in lifetime suggestion

Previously, Rebuilder did not visit type parameters when rebuilding
generics and path, so in some cases the suggestion turns out to be
erroneous.
rustc: Switch tuple structs to have private fields

This is a continuation of the work done in #13184 to make struct fields private
by default. This commit finishes RFC 4 by making all tuple structs have private
fields by default. Note that enum variants are not affected.

A tuple struct having a private field means that it cannot be matched on in a
pattern match (both refutable and irrefutable), and it also cannot have a value
specified to be constructed. Similarly to private fields, switching the type of
a private field in a tuple struct should be able to be done in a backwards
compatible way.

The one snag that I ran into which wasn't mentioned in the RFC is that this
commit also forbids taking the value of a tuple struct constructor. For example,
this code now fails to compile:

    mod a {
        pub struct A(int);
    }

    let a: fn(int) -> a::A = a::A; //~ ERROR: first field is private

Although no fields are bound in this example, it exposes implementation details
through the type itself. For this reason, taking the value of a struct
constructor with private fields is forbidden (outside the containing module).

RFC: 0004-private-fields
Switch some tuple structs to pub fields

This commit deals with the fallout of the previous change by making tuples
structs have public fields where necessary (now that the fields are private by
default).
Avoid injecting unfulfilled dependence in compiletest on libnative.
Two fixes to get `make check-stage1` working.

1. Fix a long-standing typo in the makefile: the relevant
   CTEST_NAME here is `rpass-full` (with a dash), not
   `rpass_full`.

2. The rpass-full tests depend on the complete set of target
   libraries.  Therefore, the rpass-full tests need to use
   the dependencies held in the CSREQ-prefixed variable, not
   the TLIBRUSTC_DEFAULT-prefixed variable.
After a hash mismatch error, emit file-system paths of crates involved.

Fix #13266.

There is a little bit of acrobatics in the definition of `crate_paths`
to avoid calling `clone()` on the dylib/rlib unless we actually are
going to need them.

The other oddity is that I have replaced the `root_ident: Option<&str>`
parameter with a `root: &Option<CratePaths>`, which may surprise one
who was expecting to see something like: `root: Option<&CratePaths>`.
I went with the approach here because I could not come up with code for
the alternative that was acceptable to the borrow checker.
Removed references to managed boxes/pointers from the tutorial text. Code
examples in relevant sections were similarly altered.
Removed all references to managed closures.
std: Document builtin syntax extensions

These syntax extensions need a place to be documented, and this starts passing a
`--cfg dox` parameter to `rustdoc` when building and testing documentation in
order to document macros so that they have no effect on the compiled crate, but
only documentation.

Closes #5605
Bump version to 0.11-pre

This also changes some of the download links in the documentation
to 'nightly'.
Add fetch_and, fetch_or, fetch_xor to AtomicInt, AtomicUint
stop asking LLVM to null-terminate strings

This was missed when dropping the null-termination from our string
types. An explicit null byte can still be placed anywhere in a string if
desired, but there's no reason to stick one at the end of every string
constant.
auto merge of #13237 : alexcrichton/rust/private-tuple-structs, r=brson

This is the final commit need to implement [RFC #4](https://github.com/rust-lang/rfcs/blob/master/active/0004-private-fields.md), it makes all tuple struct fields private by default, overridable with the `pub` keyword.

I'll note one divergence from the original RFC which is outlined in the first commit.
auto merge of #13296 : brson/rust/0.11-pre, r=alexcrichton

This also changes some of the download links in the documentation
to 'nightly'.
std: Remove `RefCell::get()`

It's surprising that `RefCell::get()` is implicitly doing a clone
on a value. This patch removes it and replaces all users with
either `.borrow()` when we can autoderef, or `.borrow().clone()`
when we cannot.
std: Remove `RefCell::set()`
test: avoid infinite loop in out-of-stack.rs

This fixes #13238. It avoids an infinite loop when compiling
the tests with `-g`. Without this change, the debuginfo on
`black_box` prevents the method from being inlined, which
allows llvm to convert `silent_recurse` into a tail-call. This
then loops forever instead of consuming all the stack like it
is supposed to. This patch forces inlining `black_box`, which
triggers the right error.
