reachable objects should not include categories and
category_objects because it is noisy information.
In fact, objects created after calling
ObjectSpace.reachable_objects_from_root should not be included
as a returning hash objects. Currently, mswin64 platform has a
problem because of this behaviour. Should we trace new objects?

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.

safe functions during garbage collection such as xfree().
On default, T_DATA objects are freed at same points as fianlizers.
This approach protects issues such as reported by [ruby-dev:35578].
However, freeing T_DATA objects immediately helps heap usage.
Most of T_DATA (in other words, most of dfree functions) are safe.
However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
for safety.
