oliver Kowalke 20ca3705e7 pass stack-allocator to fiber in async()

- stack-allocator was mistakenly passed as argument to packaged_task<>
- additional overload for async() taking stack-allocator for fiber and
  allocator for packaged_task<>

boost.fiber

boost.fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperatively. 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 it yields to allow another fiber to run (context switching).

A context switch between threads costs usally thousands 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.

boost.fiber requires C++11!
