auto merge of #8994 : alexcrichton/rust/upgrade-libuv, r=brson
This is a reopening of the libuv-upgrade part of #8645. Hopefully this won't
cause random segfaults all over the place. The windows regression in testing
should also be fixed (it shouldn't build the whole compiler twice).
A notable difference from before is that gyp is now a git submodule instead of
always git-cloned at make time. This allows bundling for releases more easily.

This exposes a very simple function for resolving host names. There's a lot more that needs to be done, but this is probably enough for servo to get started connecting to real websites again.

auto merge of #8909 : lkuper/rust/default-methods-refactor, r=alexcrichton
(cc: #3227)
Parts I'm unsure about and would like a reviewer to look at are:
* `pub trait GenericPath : Clone + Eq + ToStr` -- is this the done thing? I've never done trait inheritance before, let alone from multiple traits, but it seemed to be necessary to be able to call all the methods we have to be able to call on `self`.
* changing the argument of `components` from `self` to `&self`, and having it return `self.components.clone()` instead of `self.components`; this was necessary to avoid move errors, but I'm not sure if it's the right thing. (The default methods impls now all have to call `self.components()` instead of just referencing the field `self.components`.)
auto merge of #8992 : chris-morgan/rust/unreachable-macro, r=brson
Rationale: having a function which fails means that the location of
failure which is output is that of the unreachable() function, rather
than the caller.
This is part of #8991 but is not all of it; current usage of
``std::util::unreachable()`` must remain so for the moment, until a new
snapshot is made; then I will remove that function entirely in favour of
using this macro.

These commits fix bugs related to identically named statics in functions of implementations in various situations. The commit messages have most of the information about what bugs are being fixed and why.
As a bonus, while I was messing around with name mangling, I improved the backtraces we'll get in gdb by removing `__extensions__` for the trait/type being implemented and by adding the method name as well. Yay!

This is currently unsound since `bool` is represented as `i8`. It will
become sound when `bool` is stored as `i8` but always used as `i1`.
However, the current behaviour will always be identical to `x & 1 != 0`,
so there's no need for it. It's also surprising, since `x != 0` is the
expected behaviour.

auto merge of #8978 : pnkfelix/rust/make-path-api-less-allocation-happy, r=huonw
A [dialogue](https://github.com/mozilla/rust/pull/8909#discussion-diff-6102725) on PR #8909 inspired me to make this change.
r? anyone
(It is possible that `std::path` itself will soon be replaced with a new implementation that kballard's working on, as mentioned in the dialogue linked above, but this revision is simple enough that I figured I'd offer it up.)
Fix #7740: gather_loans should not recur into the items of the block.
gather_loans does not need to recurse into any items declared in the
current block. Rather than special-case `fk_item_fn` and `fk_method`,
just make the GatherLoanVisitor's visit_item method a no-op.
This indirectly implies that the example of #7740 is fixed:
fn f() {
static A: &'static char = &'A';
}
Since we do not recurse into items, we no longer encounter `&'A'`.
auto merge of #8935 : blake2-ppc/rust/reader-bytes, r=brson
An iterator that simply calls `.read_bytes()` each iteration.
I think choosing to own the Reader value and implementing Decorator to
allow extracting it is the most generically useful. The Reader type
variable can of course be some kind of reference type that implements
Reader.
In the generic form the `Bytes` iterator is well behaved itself and does not read ahead.
It performs abysmally on top of a FileStream, and much better if a buffering reader is inserted inbetween.
auto merge of #8855 : michaelwoerister/rust/captured_vars, r=jdm
This pull request includes
* support for variables captured in closures*,
* a fix for issue #8512: arguments of non-immediate type (structs, tuples, etc) passed by value can now be accessed correctly in GDB. (I managed to fix this by using `llvm::DIBuilder::createComplexVariable()`. ~~However, I am not sure if this relies on unstable implementation details of LLVM's debug info handling. I'll try to clarify this on the LLVM mailing list~~).
* simplification of the `debuginfo` module's public interface: the caller of functions like `create_local_var_metadata()` doesn't have to know and catch all cases when it mustn't call the function,
* a cleanup refactoring with unified handling for locals, [self] arguments, captured variables, and match bindings,
* and proper span information for self arguments.
\* However, see comment at https://github.com/michaelwoerister/rust/blob/1d916ace136a27e354d73d65f488603c65f65bd2/src/test/debug-info/var-captured-in-nested-closure.rs#L62 . This is the same problem as with the fix for issue #8512 above: We are probably using `llvm.dbg.declare` in an unsupported way that works today but might not work after the next LLVM update.
auto merge of #8966 : FlaPer87/rust/issue/7473, r=bblum
Current access methods are nestable and unsafe. This patch renames
current methods implementation - prepends unsafe_ - and implements 2 new
methods that are both safe and un-nestable.
In most cases this involved removing a ~str allocations or clones
(yay), or coercing a ~str to a slice. In a few places, I had to bind
an intermediate Path (e.g. path.pop() return values), so that it would
live long enough to support the borrowed &str.
And in a few places, where the code was actively using the property
that the old API returned ~str's, I had to put in to_owned() or
clone(); but in those cases, we're trading an allocation within the
path.rs code for one in the client code, so they neutralize each
other.
Note that I left dirname as returning ~str, because both of its
implementations work by calling dir_path, which produces a new path,
and thus we cannot borrow the result from &'a self passed to dirname
(because the new path returned by dir_path will not live long enough
to satisfy the lifetime 'a).

auto merge of #8954 : anasazi/rust/tcp-acceptor, r=catamorphism
The Listener trait takes two type parameters, the type of connection and the type of Acceptor,
and specifies only one method, listen, which consumes the listener and produces an Acceptor.
The Acceptor trait takes one type parameter, the type of connection, and defines two methods.
The accept() method waits for an incoming connection attempt and returns the result.
The incoming() method creates an iterator over incoming connections and is a default method.
Example:
```rust
let listener = TcpListener.bind(addr); // Bind to a socket
let acceptor = listener.listen(); // Start the listener
for stream in acceptor.incoming() {
// Process incoming connections forever (a failure will kill the task).
}

auto merge of #8947 : thestinger/rust/name, r=huonw
Storing the type name in the `tydesc` aims to avoid the need to pass a type name in almost every single visitor method.
It would likely be much saner for `repr` to simply be passed the `TyDesc` corresponding to the function or just the type name, but this is good enough for now.
