httparse is a http1 stateless push parser. This not only speeds up
parsing right now with sync io, but will also be useful for when we get
async io, since it's push based instead of pull.
BREAKING CHANGE: Several public functions and types in the `http` module
have been removed. They have been replaced with 2 methods that handle
all of the http1 parsing.
BREAKING CHANGE: added requirement that all HeaderFormat implementations
must also be fmt::Debug. This likely as easy as slapping
#[derive(Debug)] on to any custom headers.
It turns out, we don't need capabilities of MuCell (or even RefCell).
We don't to have sophisticated interior mutability. We don't ever lend
out references that may be mutated later. Instead, if there is no value
to lend, then we generate the value, require interior mutability to save
the value internally, and then we return a reference. We never ever
change a value once it's been generated. It can be changed, but only via
&mut self methods, where we can safely reason about mutability.
This means we don't need keep borrow checking code at runtime, which
helps performance. We also are able to reduce the amount of unsafe
transmutes. The internal API more safely constrains the usage of unsafe,
enforcing our invariants, instead of shotgunning unsafe usage with Refs
and promising we're doing it correctly.

Closes#252
Internals have been shuffled around such that Request and Reponse are
now given only a mutable reference to the stream, instead of being
allowed to consume it. This allows the server to re-use the streams if
keep-alive is true.
A task pool is used, and the number of the threads can currently be
adjusted by using the `listen_threads()` method on Server.

This adds a dependency on the time crate found in rust-lang/time
and fixes a field rename from tm_gmtoff to tm_utcoff.

tm_gmtoff has been renamed to tm_utcoff
Intertwining was a nice feature, but it slows down hyper significantly,
so it is being removed.
There is some fallout from this, mainly that Incoming has had its type
parameter changed to `<A = HttpAcceptor>` and Handler receiving one
bounded with `A: NetworkAcceptor`.
