Ensure Rollback Mechanism:
A rollback's function is a function to rollback a state before ensure's
function execution.
When the jump of callcc is across the scope of rb_ensure,
ensure's functions and rollback's functions are executed appropriately
for keeping consistency.
Current API is unstable, and only internal use.
ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
This API create relation ensure's function to rollback's function.
By registered rollback's function, it is executed When jumpping into
corresponding rb_ensure scope.

Postponed jobs are registered with this API. Registered jobs
are invoked at `ruby-running-safe-point' as soon as possible.
This timing is completely same as finalizer timing.
There are two APIs:
* rb_postponed_job_register(flags, func, data): register a
postponed job with data. flags are reserved.
* rb_postponed_job_register_one(flags, func, data): same as
`rb_postponed_job_register', but only one `func' job is
registered (skip if `func' is already registered).

of IFUNC frame.
When `rb_binding_new_with_cfp()' is called, VM finds out the first
normal (has iseq) frame and create a binding object of this frame
and create Env objects. `ep's of related frames are updated
(`ep's point Env object managed spaces).
However, `ep' of skipped IFUNC frame was not updated and
old invalid `ep' was remained. It causes serious problems.
To solve this issue, permit IFUNC to create binding.

Move `trace_arg' from rb_tp_t::trace_arg to rb_thread_t::trace_arg.
`trace_arg' may changed by multiple threads.
rb_thread_t::trace_arg can represent rb_thread_t::trace_running
(null or non-null) and rb_thread_t::trace_running is removed.
After that, `rb_tp_t' is not needed to check tracing or not
(A running thread knows tracing or not). This is why I remove
tp_attr_check_active() and make new function get_trace_arg().
And this modification disable to work the following code:
TracePoint.trace{|tp|
Thread.new{p tp.event} # access `tp' from other threads.

- 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).
