commit 8014e3f9e1838745a6f3af7c1e2a557bd74349b0
Author: Dmitry Zhuk <[email protected]>
Date: Tue Dec 5 11:20:55 2017 -0800
Added `CallableOnce` support in `Future`.
`Future` guarantees that callbacks are called at most once, so it can
use `lambda::CallableOnce` to expicitly declare this, and allow
corresponding optimizations with moves.

Added `CallableOnce` support in `defer`.
This allows `defer` result to be converted to `CallableOnce`, ensuring
that bound arguments are moved, when call is made, and avoiding making
copies of bound arguments.

> Currently, dispatch and defer will take copies of the provided arguments.
> Also, a protobuf message handler cannot move the supplied message. We should
> support moves for these for efficiency.
