Subject: This is the mega-ucontext commit. It replaces the task switching
 mechanism with a new one inspired by ucontext. It works under Linux, OS X and
 Windows, and is Valgrind clean on Linux and OS X (provided the runtime is
 built with gcc).

This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.
