{get,set,swap,make}context functions. Based on a initial patch by Carmelo
Amoroso.

+ Add into library the SuSv3 obsolescent functions used for context
+ control. The setcontext family allows the implementation in C of
+ advanced control flow patterns such as iterators, fibers, and
+ coroutines. They may be viewed as an advanced version of
+ setjmp/longjmp; whereas the latter allows only a single non-local jump
+ up the stack, setcontext allows the creation of multiple cooperative
+ threads of control, each with its own stack.
+ These functions are: setcontext, getcontext, makecontext, swapcontext.
