feat(hyper): switch to std::io, std::net, and std::path.

[seanmonstar]

All instances of old_io and old_path were switched to use the new
shiny std::io, std::net, and std::path modules. This means that
Request and Response implement Read and Write now.

Because of the changes to TcpListener, this also takes the opportunity
to correct the method usage of Server. As with other
languages/frameworks, the server is first created with a handler, and
then a host/port is passed to a listen method. This reverses what
Server used to do.

Closes #347

BREAKING CHANGE: Check the docs. Everything was touched.

[reem]

Needs a rebase already.

[reem]

??

[seanmonstar]

Oh dangit. I had set that when I was fixing the bench marks, to compile faster.

[seanmonstar]

@reem rebased.

Interesting to note: speed improvements with the client_mock_tcp bench is over 500%.

BEFORE
test bench_mock_hyper ... bench:    280059 ns/iter (+/- 62609)

AFTER
test bench_mock_hyper ... bench:     50152 ns/iter (+/- 5771)

I think Ok(0) is still bad behavior, unless the recent RFC changed that.

[seanmonstar]

My understanding is that Ok(0) is EOF. There no longer is an EOF error kind...

[reem]

Asked about this and you're right. (deleted the other comment on this same thing)

[seanmonstar]

If there's no real problems, I'd like to merge so we can unbreak people on crates.io...

Hey, I am not sure if this is a blocker, but with the current build the example client does not build for me. Here's the exception:

src/main.rs:19:20: 19:36 error: type `hyper::client::response::Response` does not implement any method in scope named `read_to_string`
src/main.rs:19     let body = res.read_to_string().unwrap();
                                  ^~~~~~~~~~~~~~~~
src/main.rs:19:36: 19:36 help: methods from traits can only be called if the trait is in scope; the following trait is implemented but not in scope, perhaps add a `use` for it:

error: aborting due to previous error

@akoskaaa read_to_string() was changed in the new io module. Looks like the example needs to be updated. Here is how I modified my code to make it compile:

    use std::io::Read;
    ...
    let mut body: String = "".to_string();
    try!(res.read_to_string(&mut body));

[seanmonstar]

Alright, I updated the REAME to work, and renamed that odd function. Once travis hits green, I'll merge. (sorry those using git rev's, I probably broke you because of my force-push)
