Migrate actix-net to std::future (#64)

* Migrate actix-codec, actix-rt, and actix-threadpool to std::future

* update to latest tokio alpha and futures-rs

* Migrate actix-service to std::future,

This is a squash of ~8 commits, since it included a lot of experimentation. To see the commits,
look into the semtexzv/std-future-service-tmp branch.

* update futures-rs and tokio

* Migrate actix-threadpool to std::future (#59)

* Migrate actix-threadpool to std::future

* Cosmetic refactor

- turn log::error! into log::warn! as it doesn't throw any error
- add Clone and Copy impls for Cancelled making it cheap to operate with
- apply rustfmt

* Bump up crate version to 0.2.0 and pre-fill its changelog

* Disable patching 'actix-threadpool' crate in global workspace as unnecessary

* Revert patching and fix 'actix-rt'

* Migrate actix-rt to std::future (#47)

* remove Pin from Service::poll_ready(); simplify combinators api; make code compile

* disable tests

* update travis config

* refactor naming

* drop IntoFuture trait
