Oliver Kowalke e32d499ae2 context: new layout for fcontext_t ...

- fcontext_t takes pointer to stack (lower addresses) and stack size
 - make_fcontext() computes start address of stack pointer depending on
   architecture (growing upwards, downwards)
 - make_fcontext() preserves frame pointer on intel
 - stack alignment corrected on intel
 - BOOST_USE_UCONTEXT for performance measurements added
