* 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.

* gc.c: introduce tomb heap.
  Tomb heap is where zombie objects and ghost (freed slot) lived in.
  Separate from other heaps (now there is only eden heap) at sweeping
  helps freeing pages more efficiently.
  Before this patch, even if there is an empty page at former phase
  of sweeping, we can't free it.
  Algorithm:
    (1) Sweeping all pages in a heap and move empty pages from the
        heap to tomb_heap.
    (2) Check all exsisting pages and free a page
        if all slots of this page are empty and
           there is enough empty slots (checking by swept_num)
  To introduce this pach, there are several tuning of GC parameters.

* gc.c: move increment from heap to heap_pages.
  Share `increment' information with heaps.
* gc.c: change ratio of heap_pages_free_min_page
  to 0.80.
  This change means slow down page freeing speed.
