* gc.c (gc_mark_roots): should mark the VM object itself to mark
singleton class of the VM object.
Before this patch, we only set mark bit for the VM object and
invoke mark function separately.
[Bug #12583]
* test/ruby/test_gc.rb: add a test.

* gc.c (rb_objspace_free): cause rb_bug if lazy sweep is in progress
during rb_objspace_free. Adds extra protection for r46340.
Patch by Vicent Marti. [Bug #10768] [ruby-core:67734]
* gc.c (rb_objspace_call_finalizer): Ensure GC is completed after
finalizers have run. We already call gc_rest() before invoking
finalizers, but finalizer can allocate new objects and start new GC
cycle, so we call gc_rest() again after finalizers are complete.
* gc.c (rb_objspace_call_finalizer): control GC execution during
force firnalizations at the end of interpreter process.
[Bug #10768]
1) Prohibit incremental GC while running Ruby-level finalizers
to avoid any danger.
2) Prohibit GC while invoking T_DATA/T_FILE data structure
because these operations break object relations consistency.
This patch can introduce another memory consuming issue because
Ruby-level finalizers can run after (2), GC is disabled.
However, basically object consistency was broken at (2) as I
described above. So that running Ruby-level finalizers contains
danger originally. Because of this point, I need to suggest to
remove these 3 lines (invoking remaining finalizers). And add a
rule to add that finalizers should not add new finalizers, or
say there is no guarantee to invoke finalizers that added by
another finalizer.

From Ruby 2.2, keys of GC.stat are changed [Feature #9924].
To provide compatible layer, GC.stat add a default_proc
(if default_proc of given Hash object is not set).
At first use of this compatible layer of interpreter process,
show a warning message like that:
program: GC.stat[:total_allocated_object]
warning message: "warning: GC.stat keys were changed from Ruby
2.1. In this case, you refer to obsolete `total_allocated_object'
(new key is `total_allocated_objects').
Please check <https://bugs.ruby-lang.org/issues/9924>
for more information."
Pleaes correct my English message :)

Before this patch, gc_marks_step() marks (white -> grey) fixed
number objects. However, this strategy does not fit practical
cases, for example too slow to make progres.
This patch changes this strategy how many objects the
gc_marks_step() should handle.
We can estimate how many times gc_marks_step() is called during
this major marking (== C) with the free slot number in pooled
pages. We also can estimate the living object number (== L)
using last marked_slots value. We can solve this problem (how
many objects should be process in gc_marks_step()) by L/C.
* gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_sltos and
step_slots.
