Fix Fiber with Thread issue on Windows [Bug #14642]
* cont.c (rb_threadptr_root_fiber_setup): divide into two functions: * rb_threadptr_root_fiber_setup_by_parent(): called by the parent thread. * rb_threadptr_root_fiber_setup_by_child(): called by the created thread. `rb_threadptr_root_fiber_setup()` is called by the parent thread and set fib->fib_handle by ConvertThreadToFiber() on the parent thread on Windows enveironment. This means that root_fib->fib_handle of child thread is initialized with parent thread's Fiber handle. Furthermore, second call of `ConvertThreadToFiber()` for the same thread fails. This patch solves this weird situateion. However, maybe we can make more clean code. * thread.c (thread_start_func_2): call `rb_threadptr_root_fiber_setup_by_child()` at thread initialize routine. * vm.c (th_init): call `rb_threadptr_root_fiber_setup_by_parent()`. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
