The old `tokio-core` crate is deprecated in favour of the `tokio` crate,
which also provides the new multithreaded Tokio runtime. Although `h2`
is generic over the runtime, the examples do depend on `tokio`.
This branch update the example code to use the new `tokio` library
rather than `tokio-core`. It also updates the examples in `RustDoc`.
For the most part, this was pretty trivial --- simply replacing
`handle.spawn(...)` with `tokio::spawn(...)` and `core.run(...)` with
`tokio::run(...)`. There were a couple of cases where error and item
types from spawned futures had to be mapped to `(), ()`. Alternatively,
this could have been avoided by using the single-threaded runtime and
calling `block_on` instead to await the value of those futures, but I
thought it was better to reduce the amount of tokio-specific code in the
examples.

Avoid the need for indexmap-based applications to build ordermap,
which is the old name for indexmap.

Upgrade to env_logger 0.5 and log 0.4 so that projects that use those
versions don't have to build both those versions and the older ones
that h2 is currently using.
Don't enable the regex support in env_logger. Applications that want
the regex support can enable it themselves; this will happen
automatically when they add their env_logger dependency.
Disable the env_logger dependency in quickcheck.
The result of this is that there are fewer dependencies. For example,
regex and its dependencies are no longer required at all, as can be
seen by observing the changes to the Cargo.lock. That said,
env_logger 0.5 does add more dependencies itself; however it seems
applications are going to use env_logger 0.5 anyway so this is still
a net gain.
