The following types are renamed:
```rust
block_ => Block
block => @mut Block
fn_ctx_ => FunctionContext
fn_ctx => @mut FunctionContext
scope_info => ScopeInfo
```
I also tried to convert instances of `@mut` to `&mut` or `&` but a lot of them are blocked by issue #6268, so I left it for some time later.
Factor out internal methods to pop/push list nodes so that .merge() and .rotate_to_front(), .rotate_to_back() (new methods) can be implemented without allocating nodes.
With that, some cleanup changes to DList use of Option, and adding a missing Encodable implementation.
SmallIntSet is equivalent to BitvSet but with 64 times the memory
overhead. There's no reason for it to exist.
SmallIntSet's overhead should really only be 8 times, but for some
reason, `sys::size_of::<Option<()>>() == 8`, not 1.
This allows for control over the section placement of static, static
mut, and fn items. One caveat is that if a static and a static mut are
placed in the same section, the static is declared first, and the static
mut is assigned to, the generated program crashes. For example:
#[link_section=".boot"]
static foo : uint = 0xdeadbeef;
#[link_section=".boot"]
static mut bar : uint = 0xcafebabe;
Declaring bar first would mark .bootdata as writable, preventing the
crash when bar is written to.
Switched Bitv and BitvSet to external iterators. They still use some internal iterators internally (ha).
Derived clone for all Bitv types.
Removed indirection in BitvVariant. It previously held a unique pointer to the appropriate Bitv struct, even though those structs are the size of a pointer themselves. BitvVariant is the same size (16 bytes) as it was previously.
My first bit of newsched IO work. Pretty simple and limited in scope.
the RtioTimer trait only has a `sleep(msecs: u64)` method, for now. Taking requests on what else ought to be here.
oh yeah: this resolves#6435
This removes all the code from libextra that depends on libuv. After that it removes three runtime features that existed to support the global uv loop: weak tasks, runtime-global variables, and at_exit handlers.
The networking code doesn't have many users besides servo, so shouldn't have much fallout. The timer code though is useful and will probably break out-of-tree code until the new scheduler lands, but I expect that to be soon.
It also incidentally moves `os::change_dir_locked` to `std::unstable`. This is a function used by test cases to avoid cwd races and in my opinion shouldn't be public (#7870).
Closes#7251 and #7870
.peek_next() needs to check the element counter just like the .next()
and .next_back() iterators do.
Also clarify .insert_next() doc w.r.t double ended iteration.

AST spanned<T> refactoring, AST type renamings:
`crate => Crate`
`local => Local`
`blk => Block`
`crate_num => CrateNum`
`crate_cfg => CrateConfig`
`field => Field`
Also, Crate, Field and Local are not wrapped in spanned<T> anymore.

These changes remove unnecessary basic blocks and the associated branches from
the LLVM IR that we emit. Together, they reduce the time for unoptimized builds
in stage2 by about 10% on my box.
