Bring back `split` utility as a free fn instead of a method on
`AsyncRead`. This utility wraps the `stream` in an `Arc` and uses mutual
exclusion to ensure correct access.
Additionally, the specialized `split_mut` fn on TcpStream and UdsStream
is promoted to `split`.
A first pass at updating Tokio to use `std::future`.
Implementations of `Future` from the futures crate are updated to implement
`Future` from std. Implementations of `Stream` are moved to a feature flag.
This commits disables a number of crates that have not yet been updated.
* io: ensure ReadHalf/WriteHalf do not return WouldBlock directly
These facades were passing back WouldBlock when the internal BiLock
couldn't be acquired, which does not fit the intended behavior.

* io: pull from the local crate, not crates.io
