* thread.c (rb_threadptr_async_errinfo_*): manage async errors queue.

  Async events such as an exception throwed by Thread#raise,
  Thread#kill and thread termination (after main thread termination)
  will be queued to th->async_errinfo_queue.
  - clear: clear the queue.
  - enque: enque err object into queue.
  - deque: deque err object from queue.
  - active_p: return 1 if the queue should be checked.
  rb_thread_t#thrown_errinfo was removed.
* vm_core.h: add declarations of rb_threadptr_async_errinfo_*.
  remove rb_thread_t#thrown_errinfo field and
  add rb_thread_t#async_errinfo_queue (queue body: Array),
  rb_thread_t#async_errinfo_queue_checked (flag),
  rb_thread_t#async_errinfo_mask_stack(Array, not used yet).
* vm.c (rb_thread_mark): fix a mark function.
* cont.c (rb_fiber_start): enque an error.
* process.c (after_fork): clear async errinfo queue.
