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.

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.

evaluation order. [Bug #4400] [ruby-core:35237]
* eval_jump.c (rb_mark_end_proc): ditto.
* test/ruby/test_beginendblock.rb (TestBeginEndBlock#test_nested_at_exit):
added a test for nested at_exit.
* test/ruby/test_beginendblock.rb (TestBeginEndBlock#test_beginendblock):
changed the test to adopt new spec.

* vm_insnhelper.c (vm_yield_with_cfunc): vm_yield_with_cfunc receives
blockptr and passes it to iterating block.
* proc.c (rb_proc_call), include/ruby/intern.h: rb_proc_call receives
blockptr. "rb_proc_call(self, args, blockptr)" in C corresponds to
"self.call(*args, &block)" in Ruby.
* proc.c (proc_call): pass blockptr to block that is written in C.
* proc.c (curry): receive blockptr and pass it to original proc.
[ruby-core:15551]
* vm.c (invoke_block_from_c): fix for change of vm_yield_with_cfunc.
* thread.c (call_trace_proc), eval_jump.c (rb_call_end_proc): fix for
change of rb_proc_call.

by "vm.c".
* vm_eval.c: added. Some codes are moved from "eval.c"
* common.mk: fix for above changes.
* compile.c: make a vm_eval(0)
* eval.c, eval_error.c, eval_intern.h, eval_jump.c, proc.c, vm.c,
id.c, id.h, vm_core.h, vm_dump.c, vm_evalbody.c, vm_insnhelper.c,
blockinlining.c: fix for above changes. and do some refactoring.
this changes improve rb_yield() performance.
