9110a38cbf Remove rt::io::support
This removes the PathLike trait associated with this "support module". This is
yet another "container of bytes" trait, so I didn't want to duplicate what
already exists throughout libstd. In actuality, we're going to pass of C strings
to the libuv APIs, so instead the arguments are now bound with the 'ToCStr'
trait instead.

Additionally, a layer of complexity was removed by immediately converting these
type-generic parameters into CStrings to get handed off to libuv apis.

0cad984765 Migrate Rtio objects to true trait objects
This moves as many as I could over to ~Trait instead of ~Typedef. The only
remaining one is the IoFactoryObject which should be coming soon...

35756fbcf6 Move rt::io::stdio from FileStream to a TTY
We get a little more functionality from libuv for these kinds of streams (things
like terminal dimentions), and it also appears to more gracefully handle the
stream being a window. Beforehand, if you used stdio and hit CTRL+d on a
process, libuv would continually return 0-length successful reads instead of
interpreting that the stream was closed.

I was hoping to be able to write tests for this, but currently the testing
infrastructure doesn't allow tests with a stdin and a stdout, but this has been
manually tested! (not that it means much)

32b07c6a40 Remove unbound pipes from io::pipe
This isn't necessary for creating processes (or at least not right now), and
it inherently attempts to expose implementation details.

1db783bdcf Finish implementing io::net::addrinfo
This fills in the `hints` structure and exposes libuv's full functionality for
doing dns lookups.

cb7756a81d Implement process bindings to libuv
This is a re-landing of , except that the bindings are *not* being used to
power std::run just yet. Instead, this adds the bindings as standalone bindings
inside the rt::io::process module.

I made one major change from before, having to do with how pipes are
created/bound. It's much clearer now when you can read/write to a pipe, as
there's an explicit difference (different types) between an unbound and a bound
pipe. The process configuration now takes unbound pipes (and consumes ownership
of them), and will return corresponding pipe structures back if spawning is
successful (otherwise everything is destroyed normally).

0948f54e65 std::rt: Add get_host_addresses function
This is a very simplistic method for host name resolution. It converts
a host name to a vector of IP addresses. Should be enough to get started.

58b2ff9f56 Split out starting a listener from accepting incoming connections.
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:

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 (or until you break out of the loop)
}

f6d897d7d9 std: rt::io::file::FileStream fleshed out.. needs more work.. see extended
- change all uses of Path in fn args to &P
- FileStream.read assumptions were wrong (libuv file io is non-positional)
- the above will mean that we "own" Seek impl info .. should probably
  push it in UvFileDescriptor..
- needs more tests

0bc1ca4045 auto merge of : anasazi/rust/homing-io, r=brson
libuv handles are tied to the event loop that created them. In order to perform IO, the handle must be on the thread with its home event loop. Thus, when as task wants to do IO it must first go to the IO handle's home event loop and pin itself to the corresponding scheduler while the IO action is in flight. Once the IO action completes, the task is unpinned and either returns to its home scheduler if it is a pinned task, or otherwise stays on the current scheduler.

Making new blocking IO implementations (i.e. files) thread safe is rather simple. Add a home field to the IO handle's struct in uvio and implement the HomingIO trait. Wrap every IO call in the HomingIO.home_for_io method, which will take care of the scheduling.

I'm not sure if this remains thread safe in the presence of asynchronous IO at the libuv level. If we decide to do that, then this set up should be revisited.

35e844ffc1 Make IO thread-safe.
Each IO handle has a home event loop, which created it.
When a task wants to use an IO handle, it must first make sure it is on that home event loop.
It uses the scheduler handle in the IO handle to send itself there before starting the IO action.
Once the IO action completes, the task restores its previous home state.
If it is an AnySched task, then it will be executed on the new scheduler.
If it has a normal home, then it will return there before executing any more code after the IO action.

9046516444 Rename IpAddr -> SocketAddr, extract IpAddr from SocketAddr
multicast functions now take IpAddr (without port), because they dont't
need port.

Uv* types renamed:
* UvIpAddr -> UvSocketAddr
* UvIpv4 -> UvIpv4SocketAddr
* UvIpv6 -> UvIpv6SocketAddr

"Socket address" is a common name for (ip-address, port) pair (e.g. in
sockaddr_in struct).
