Oliver Kowalke b3660a3432 reorder member variables of context

- member hooks must be destroyed before execution_context
- otherwise an segementation fault is caused
- destruction of execution_context deallocates stack on which
  the member variables of context are allocated

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!
