to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.
* cont.c (rb_fiber_close): added to terminate fibers explicitly.

* vm_insnhelper.c (rb_threadptr_stack_overflow): rb_fatal is not
available during GC. raise the preallocated fatal error.

* vm_core.h: Ruby processes run with two stacks, a machine stack and a
VM stack. To make it clear, this fix renames
rb_execution_context_t::stack(_size) to vm_stack(_size).

exception instance, and a cause from a previous exception.

warning too.

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.

The goal is to reduce rb_context_t and rb_fiber_t size
by removing the need to store the entire rb_thread_t in
there.
[ruby-core:81045] Work-in-progress: soon, we will move more fields here.

Use volatile instead of optnone to avoid optimization which causes
segmentation faults.

[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.
