This patch refactors `length_delimited` to be implemented as a `Codec` and
use the default `Framed` wrapper types.
The original implementation did not do this in order to support vectored writes in the
write half. However, this implementation would be more efficient with small frames anyway.
If vectored writes are to be explored in the future, then it should be done holistically.

This patch keeps the primary net types in `tokio::net` and moves
secondary types to a protocol specific submodules.
Primary types are the ones that users are most likely to name (`TcpStream`,
`TcpListener`, `UdpSocket`, ...)
Secondary types are the operation futures.
Re-export it inside the tokio::runtime::current_thread, as the original
place (tokio::executor::current_thread) is hidden from documentation and
users need some way to spawn non-Send futures.
This patch introduces `Timeout`. This new type allows setting a timeout
both using a duration and an instant. Given this overlap with
`Deadline`, `Deadline` is deprecated.
In addition to supporting future timeouts, the `Timeout` combinator is
able to provide timeout functionality to streams. It does this by
applying a duration based timeout to each item being yielded.
The main reason for introducing `Timeout` is that a deadline approach
does not work with streams. Since `Timeout` needed to be introduced
anyway, keeping `Deadline` around does not make sense.
This patch adds a `DelayQueue` to tokio_timer. The `DelayQueue` allows
inserting elements as well as specifying a time at which the element
should be returned to the user. This allows handling more complex
timeout situations.
The futures 0.2 crate is not intended for widespread usage. Also, the
futures team is exploring the compat shim route.
If futures 0.3 support is added to Tokio 0.1, then a different
integration route will be explored, making the current code unhelpful.

docs.rs is smart enough to show docs for the latest M.N.P release when
M.N is used in the link. For example:
https://docs.rs/mio/0.6/mio/struct.Poll.html
..will show mio 0.6.14 and later docs. While using the `M.N.*`
(ASTERISK) syntax also works, `M.N` is the more common usage, so
standarize a few existing links to that format.

Relates to #421
Extract `tokio::executor::current_thread` to a tokio-current-thread
crate. Deprecated fns stay in the old location. The new crate only
contains thee most recent API.
Currently, the timer uses a `Now` trait to abstract the source of time.
This allows time to be mocked out. However, the current implementation
has a number of limitations as represented by #288 and #296.
The main issues are that `Now` requires `&mut self` which prevents a
value from being easily used in a concurrent environment. Also, when
wanting to write code that is abstract over the source of time, generics
get out of hand.
This patch provides an alternate solution. A new type, `Clock` is
provided which defaults to `Instant::now` as the source of time, but
allows configuring the actual source using a new iteration of the `Now`
trait. This time, `Now` is `Send + Sync + 'static`. Internally, `Clock`
stores the now value in an `Arc<Now>` value, which introduces dynamism
and allows `Clock` values to be cloned and be `Sync`.
Also, the current clock can be set for the current execution context
using the `with_default` pattern.
Because using the `Instant::now` will be the most common case by far, it
is special cased in order to avoid the need to allocate an `Arc` and use
dynamic dispatch.
This patch adds a new crate: tokio-fs. This crate provides a wrapper
around `std` functionality that can only be performed using blocking
operations. This primarily includes filesystem operations, but it also
includes standard input, output, and error access as these streams
cannot be safely switched to non-blocking mode in a portable way.
These wrappers call the `std` functions from within a `blocking`
annotation which allows the runtime to compensate for the fact that the
thread will potentially remain blocked in a system call.
This patch introduces a version of `Runtime` that runs all components on
the current thread. This allows users to spawn futures that do not implement
`Send`.
This ensures that all fd-based futures are put into the queue for the
current tick, if the CurrentThread is parking via the Reactor.
Otherwise, if there are queued up futures already, only those would be
polled in the turn. These futures could then notify others/themselves to
have the queue still non-empty on the next turn. Which then potentially
allows the reactor to never be polled, and thus fd-based futures are
never queued up and polled.
Also return in the Turn return value whether any futures were polled at
all, which allows the caller to know if any work was done at all in this
turn and based on that adjust behavior.
This patch renames `Sleep` from tokio-timer and the tokio facade to
`Delay`. Given that the future does not actually put anything to sleep,
the `Delay` name feels more appropriate.
Fixes#263
This patch integrate the new timer implementation with the runtime by
initializing a timer per worker thread. This allows minimizing the
amount of synchronization needed for using timers.
