  from Thread.async_interrupt_timing to Thread.handle_interrupt,
  from Thread.async_interrupted? to Thread.pending_interrupt?.
  Also rename option from `defer' to `never'.
  [ruby-core:51074] [ruby-trunk - Feature #6762]
* vm_core.c, thread.c: rename functions and data structure
  `async_errinfo' to `pending_interrupt'.
* thread.c: add global variables sym_immediate, sym_on_blocking and
  sym_never.
* cont.c, process.c, vm.c, signal.c: ditto.
* lib/sync.rb, lib/thread.rb: catch up this renaming.
* test/ruby/test_thread.rb: ditto.

  enqueue error into async_errinfo_queue, because you cannot call
  TH_TAG_JUMP() in this function. [ruby-dev:45218]  [Bug #5993]

* thread.c (rb_threadptr_execute_interrupts): now INT2FIX(TAG_FATAL)
  can be popped from async_errinfo_queue.

* vm.c (rb_vm_make_jump_tag_but_local_jump): revert r38441.
  rb_vm_make_jump_tag_but_local_jump() shouldn't return exception
  in case of state == TAG_FATAL.

* test/ruby/test_fiber.rb (test_exit_in_fiber): fix a test to illuminate
  Thread.exit should terminate current Thread.

  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.
  }
  I believe nobody mix threads at trace procedure.
  This is current limitation.
* cont.c (fiber_switch, rb_cont_call): use rb_thread_t::trace_arg
  instead of rb_thread_t::trace_running.
* test/ruby/test_settracefunc.rb: add a multi-threading test.

  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).
* vm_core.h (rb_vm_t::default_params): add to record above settings.
* vm.c (RubyVM::DEFAULT_PARAMS): add new constant to see
  above setting.
* thread_pthread.c: support RUBY_THREAD_MACHINE_STACK_SIZE.
* cont.c: support RUBY_FIBER_(VM|MACHINE)_STACK_SIZE.
* test/ruby/test_fiber.rb: add tests for above.
* test/ruby/test_thread.rb: ditto.

  rb_vm_make_jump_tag_but_local_jump() could return Qnil (ex. when
  finished by Thread.exit). [ruby-dev:45218] [Bug #5993]

* test/ruby/test_fiber.rb (test_exit_in_fiber): add test for it.

  entry with VM_METHOD_TYPE_REFINED holds only the original method
  definition, so ci->me is set to a method entry allocated in the
  stack, and it causes SEGV/ILL.  In this commit, a method entry
  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
  avoid GC for iclasses created by copy_refinement_iclass().

* vm_method.c (rb_method_entry_make): add a method entry with
  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
  the target module is a refinement.  When a method entry with
  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
  the same name is searched in refinements.  If such a method is
  found, the method is invoked.  Otherwise, the original method in
  the refined class (rb_method_definition_t::body.orig_me) is
  invoked.  This change is made to simplify the normal method lookup
  and to improve the performance of normal method calls.

* vm_method.c (EXPR1, search_method, rb_method_entry),
  vm_eval.c (rb_call0, rb_search_method_entry): do not use
  refinements for method lookup.

* vm_insnhelper.c (vm_call_method): search methods in refinements if
  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
  super (i.e., ci->call == vm_call_super_method), skip the same
  method entry as the current method to avoid infinite call of the
  same method.

* class.c (include_modules_at): add a refined method entry for each
  method defined in a module included in a refinement.

* class.c (rb_prepend_module): set an empty table to
  RCLASS_M_TBL(klass) to add refined method entries, because
  refinements should have priority over prepended modules.

* proc.c (mnew): use rb_method_entry_with_refinements() to get
  a refined method.

* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
  copy_refinement_iclass().

* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.

* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
  the test because it should pass successfully.

* test/ruby/test_refinement.rb (test_redefine_refined_method): new
  test for the case a refined method is redefined.

  `bp' can be calculate by `sp' (stack pointer) of previous frame.
  Now, `bp_check' field is remained for debug.  You can eliminate
  this field by setting  VM_DEBUG_BP_CHECK as 0.
* vm_insnhelper.c (vm_base_ptr): add `vm_base_ptr(cfp).
  This function calculates base pointer from cfp.
* vm_insnhelper.c (vm_setup_method): push `recv' value on top of
  value stack (before method parameters).
  This change is for keeping consistency with normal method dispatch.
* insns.def: fix to use vm_base_ptr().
* vm.c (vm_exec): ditto.
* vm_dump.c: remove `bp' related dumps.
* cont.c (fiber_init): fix to check VM_DEBUG_BP_CHECK.
