* cont.c (rb_context_t): introduce saved_ec instaad of saved_thread.
We only need to transfer ec data (not all of thread data).
Introduce `thread_value` field to point creation thread.
To acccess this field, `cont_thread_value()` is introduced.
* vm.c (rb_execution_context_mark): remove `static` and use it
from cont.c (use this function instead of `rb_thread_mark`).
* vm_insnhelper.c (rb_vm_push_frame): accept ec instead of th.

* cont.c (fiber_store): move `cont_save_machine_stack()` timing to
avoid `fiber_verify()` false positive on `FIBER_USE_NATIVE == 0`
and `GC.stress = true`.
This patch is very dirty and it should be removed soon.

* cont.c (cont_save_thread): clear only `stack_end`. Clearing tells
GC mark function to ignore this macine stack (not allocated yet).
`stack_start` will be used by machine stack store/restore phase
(on FIBER_USE_NATIVE == 0), so that only `stack_end` is cleared.

* cont.c: revisit fiber status.
"FIBER_RUNNING" status represents fiber is resumed or suspended.
This fix separate these two status explicitly.
FIBER_CREATED: Just after Fiber.new. Not resumed yet.
FIBER_RESUMED (new): Fiber#resumed. Now this fiber is running.
FIBER_SUSPENDED (new): Suspended by Fiber.yield. Not running.
FIBER_TERMINATED: Terminated.
Add sevral assertions to check consistency with these status.
* cont.c (fiber_status_set): added to change status.
* cont.c (FIBER_xxx_P): added to check fiber status.

* cont.c (root_fiber_alloc): this function is called by fiber_current()
and fiber_store(). fiber_current() should clear VM stack information
in a fiber data because runnning thread knows stack information and has
responsibility to manage it. However fiber_store() requires to remain
VM stack information in a fiber data because the responsibility to manage
VM stack is moved to the Fiber from the Thread (and switch to another
fiber).
* cont.c (root_fiber_alloc): save thread's fiber and root_fiber information.

* cont.c: r55766 change the handling method of Fiber's VM stack.
Resumed Fiber points NULL as VM stack and running Thread has
responsibility to manage it (marking and releasing).
However, thread_start_func_2()@thread.c and thread_free()@vm.c
doesn't free the VM stack if corresponding root Fiber is exist.
This causes memory leak. [Bug #13772]
* cont.c (root_fiber_alloc): fib->cont.saved_thread.ec.stack should be NULL
because running thread has responsibility to manage this stack.
* vm.c (rb_thread_recycle_stack_release): assert given stack is not NULL
(callers should care it).

Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.
Some code used "status" instead of "state". To make them clear,
rename them to state.
We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

[Bug #12628]
This patch introduce many changes.
* Introduce concept of "Block Handler (BH)" to represent
passed blocks.
* move rb_control_frame_t::flag to ep[0] (as a special local
variable). This flags represents not only frame type, but also
env flags such as escaped.
* rename `rb_block_t` to `struct rb_block`.
* Make Proc, Binding and RubyVM::Env objects wb-protected.
