Routine dependencies update

[mati865]

env_logger::init() now panics if it's already initialised.
All the tests passed on Linux.

Looks good to me. 👍

I've missed recently added tokio-tls, going to fix that.

[mati865]

Hmm, deprecated https://github.com/rust-lang-deprecated/tempdir still pulls rand 0.4.
Should I replace it with tempfile?

[mati865]

I was getting Error(Shutdown) trying to fix tokio-threadpool\examples\smoke.rs for tokio-timer = "0.2".
In the end just reverted it to tokio-timer = "0.1", CI should pass now.

Should I replace it with tempfile?

Sure

Re Error(Shutdown) it would be nice to be able to use tokio-timer 0.2, but I can try to make that update later.

I was running cargo test with out --all before. Now everything seems fine.

@carllerche looks like this is ready for merge?

[carllerche]

Ag... looks like there are conflicts :( sorry.

[mati865]

No problem, all green now.

NOTE: tokio-timer dev-dependency for threadpool is still outdated.
