Update tokio-core uses to tokio-0.1

[Marwes]

reqwest has received an update to drop its tokio-core dependency so it is now possible to move to using tokio here as well.

hyperx were pulled it to paper over hyper's removal of typed headers but were otherwise avoided.

Since there are quite a few non-Send futures I had to use current_thread::Runtime instead of the standard multi-threaded runtime.

I'm probably missing some bit of information, but what's the motivation behind these changes?

[Marwes]

Just a follow up of #286. tokio-core is deprecated with tokio as the replacement.

[Marwes]

Forgot I need to cleanup this part. tokio-proto is unmaintained so I had to string together a minimal version of it instead but it still uses some of tokio-proto's types which makes it a bit of a mess.

Marwes@0faa567 might be a bit more palatable, it is on this branch https://github.com/Marwes/sccache/commits/fmt_plus_tokio which formats the entire project first so that any accidental formatting changes are in a separate commit, and all the behavioural changes are in the second commit.

Thanks for the PR! I think this will need to wait until we land the last few sccache-dist PRs. #323 should be the second-to-last one.

[joshuawarner32]

Hi! I think I've been running into #248 (which might be fixed by this) - any updates on getting this landed?

[luser]

We're very close to finishing landing all the distributed compilation work--I'll get this landed as soon as that's all done.

[luser]

OK, I apologize for how long this has taken, but if you want to rebase this one last time I will merge it immediately.

[Marwes]

Rebased but seem to have broken something in the distributed compilation. Will try and debug it.

[luser]

Thanks! Sorry that this took so long to merge that you had to rebase it several times.
