* 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.

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.

RUBY_INTERNAL_EVENT_GC_ENTER and
RUBY_INTERNAL_EVENT_GC_EXIT.
When invoking GC process, GC_ENTER event is called.
When exiting from GC process, GC_EXIT event is called.
Incremental GC (incremental marking and lazy sweep) can call
these events many times.
For example (minor marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(minor marking)
- (3) GC_END_MARK
(start lazy sweep)
(4) GC_EXIT
(ruby process)
(5) GC_ENTER
(lazy sweep)
(6) GC_EXIT
(ruby process)
(... repeat (5), (6))
(7) GC_ENTER
(finish lazy sweep)
- (8) GC_END_SWEEP
(9) GC_EXIT
2nd example (incremental major marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(start incremental marking)
(3) GC_EXIT
(ruby process)
(4) GC_ENTER
(incremental marking)
(5) GC_EXIT
(ruby process)
(... repeat (4), (5))
(6) GC_ENTER
(finish incremental marking)
- (7) GC_END_MARK
(start lazy sweep)
(8) GC_EXIT
(ruby process)
(9) GC_ENTER
(lazy sweep)
(10) GC_EXIT
(ruby process)
(... repeat (9), (10))
(11) GC_ENTER
(finish lazy marking)
- (12) GC_STOP_SWEEP
(13) GC_EXIT
Thease internal events enable to measure GC pause time completely.
