heap_tomb_page_length.
* test/ruby/test_gc.rb: fix to use GC.stat[:heap_eden_page_length]
instead of GC.stat[:heap_length].
This test expects `heap_eden_page_length' (used pages size).

if HAVE_MALLOC_USABLE_SIZE (or _WIN32) is defined.
We don't need these function if malloc_usable_size() is available.
* gc.c: catch up this change.
* gc.c: define HAVE_MALLOC_USABLE_SIZE on _WIN32.
* array.c (ary_resize_capa): do not use ruby_sized_xfree() with
local variable to avoid "unused local variable" warning.
This change only has few impact.
* string.c (rb_str_resize): ditto.

(oldspace -> oldmalloc for variable names)
OLDSPACE is confusing because it is not includes slots.
To more clearly, rename such as (oldspace_limit -> oldmalloc_limit).
It is clear that it measures (estimates) malloc()'ed size.

Basically, make an object graph of all of living objects before and
after marking and check status.
[Before marking: check WB sanity]
If there is a non-old object `obj' pointed from old object
(`parent') then `parent' or `obj' should be remembered.
[After marking: check marking miss]
Traversible objects with the object graph should be marked.
(However, this alert about objects pointed by machine context
can be false positive. We only display alert.)
[Implementation memo]
objspace_allrefs() creates an object graph.
The object graph is represented by st_table, key is object (VALUE)
and value is referring objects. Referring objects are stored by
"struct reflist".
* gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init.
This pre-allocation causes failure on is_mark_stask_empty()
without any pushing.

rb_fstring() used rb_gc_mark() to avoid freeing used string.
However, rb_gc_mark() set mark bit *and* pushes mark_stack.
rb_gc_resurrect() does only set mark bit if it is before sweeping.

vm_malloc_increase() can be called without GVL.
However, gc_rest_sweep() assumes acquiring GVL.
To avoid this problem, check GVL before gc_rest_sweep().
[Bug #9090]
This workaround introduces possibility to set malloc_limit as
wrong value (*1). However, this may be rare case. So I commit it.
*1: Without rest_sweep() here, gc_rest_sweep() can decrease
malloc_increase due to ruby_sized_xfree().

This is another approach to solve an issue discussed at r43530.
This feature is diabled as default.
This feature measures an increment of memory consuption by oldgen
objects. It measures memory consumption for each objects when
the object is promoted. However, measurement of memory consumption
is not accurate now. So that this measurement is `estimation'.
To implement this feature, move memsize_of() function from
ext/objspace/objspace.c and expose rb_obj_memsize_of().
Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
measure memory size, so that we ignores T_DATA objects now.
For example, some functions skip NULL check for pointer.
The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
and turned off as default.
We need to compare 3gen GC and this feature carefully.
(it is possible to enable both feature)
We need a help to compare them.
* internal.h: expose rb_obj_memsize_of().
* ext/objspace/objspace.c: use rb_obj_memsize_of() function.
* cont.c (fiber_memsize): fix to check NULL.
* variable.c (autoload_memsize): ditto.
* vm.c (vm_memsize): ditto.
