* vm_trace.c: exterminate Zombies.
  There is a bug that T_ZOMBIE objects are not collected.
  Because there is a pass to miss finalizer postponed job
  with multi-threading. This patch solve this issue.
* vm_trace.c (rb_postponed_job_register_one): set
  RUBY_VM_SET_POSTPONED_JOB_INTERRUPT(th) if another same job
  is registered.
  There is a possibility to remain a postponed job without
  interrupt flag.
* vm_trace.c (rb_postponed_job_register_one): check interrupt
  carefully.
* vm_trace.c (rb_postponed_job_register_one): use additional space
  to avoid buffer full.
* gc.c (gc_finalize_deferred_register): check failure.
* thread.c (rb_threadptr_execute_interrupts): check
  `postponed_job_interrupt' immediately.  There is a possibility
  to miss this flag.

* gc.c: allow multiple heaps.
  Now, objects are managed by page. And a set of pages is called heap.
  This commit supports multiple heaps in the object space.
  * Functions heap_* and rb_heap_t manages heap data structure.
  * Functions heap_page_* and struct heap_page manage page data
    strcuture.
  * Functions heap_pagse_* and struct rb_objspace_t::heap_pages
    maintains all pages.
    For example, pagaes are allocated from the heap_pages.
  See https://bugs.ruby-lang.org/projects/ruby-trunk/wiki/GC_design
  and https://bugs.ruby-lang.org/attachments/4015/data-heap_structure_with_multiple_heaps.png
  for more deitals.
  Now, there is only one heap called `eden', which is a space for all
  new generated objects.
