This allows raising exceptions in another fiber, similarly to
Thread#raise.

Remove the remainder of ROOT_FIBER_CONTEXT use and unnecessary
differences between the root and non-root fiber. This makes
it easier to follow new root fiber at fork time.
Multiple sources of truth often leads to bugs, as in this case.
We can determinte root fiber by checking a fiber against the root_fiber
of its owner thread. The new `fiber_is_root_p' function
supports that.
Now, we can care only about free-ing/recycling/munmap-ing stacks
as appropriate.

Otherwise, th->root_fiber can point to an invalid Fiber,
because Fibers do not live across fork. So consider
whatever Fiber is running the root fiber.

* 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()`.

Specified by the following environment variaables:
- RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
default: 128KB (32bit CPU) or 256KB (64bit CPU).
- RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
creation. default: 512KB or 1024KB.
- RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
default: 64KB or 128KB.
- RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
creation. default: 256KB or 256KB.
This values are specified at launched timing. You can not change
these values at running time.
Environ variables are only *hints* because:
- They are aligned to 4KB.
- They have minimum values (depend on OSs).
- Machine stack settings are ignored by some OSs.
Default values especially fiber stack sizes are increased.
This change affect Fiber's behavior:
(1) You can run more complex program on a Fiber.
(2) You can not make many (thousands) Fibers because of
lack of address space (on 32bit CPU).
If (2) bothers you,
(a) Use 64bit CPU with big memory, or
(b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
You need to choose correct stack size carefully. These values
are completely rely on systems (OS/compiler and so on).
