Nat Goodspeed 46c696f5f6 Eliminate obsolete promise_completion_token.hpp header.

This was used in an earlier implementation of use_future (no longer present)
and fibers::asio::yield (completely reimplemented).

boost.fiber

boost.fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperativly. The API contains classes and functions to manage and synchronize fibers similiar to boost.thread.

A fiber is able to store the current execution state, including all registers and CPU flags, the instruction pointer, and the stack pointer and later restore this state. The idea is to have multiple execution paths running on a single thread using a sort of cooperative scheduling (threads are preemptively scheduled) - the running fiber decides explicitly when its yields to allow another fiber to run (context switching).

A context switch between threads costs usally thousends of CPU cycles on x86 compared to a fiber switch with less than 100 cycles. A fiber can only run on a single thread at any point in time.

Building: Detailed instructions can be found at https://svn.boost.org/trac/boost/wiki/TryModBoost.

boost.fiber is C++14-only!
