* gc.c: add 3gen GC patch, but disabled as default.
  RGenGC is designed as 2 generational GC, young and old generation.
  Young objects will be promoted to old objects after one GC.
  Old objects are not collect until major (full) GC.
  The issue of this approach is some objects can promoted as old
  objects accidentally and not freed until major GC.
  Major GC is not frequently so short-lived but accidentally becoming
  old objects are not freed.
  For example, the program "loop{Array.new(1_000_000)}" consumes huge
  memories because short lived objects (an array which has 1M
  elements) are promoted while GC and they are not freed before major
  GC.
  To solve this problem, generational GC with more generations
  technique is known. This patch implements three generations gen GC.
  At first, newly created objects are "Infant" objects.
  After surviving one GC, "Infant" objects are promoted to "Young"
  objects.
  "Young" objects are promoted to "Old" objects after surviving
  next GC.
  "Infant" and "Young" objects are collected if it is not marked
  while minor GC. So that this technique solves this problem.
  Representation of generations:
  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]
  * Young :  FL_PROMOTED and !oldgen_bitmap [10]
  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
  The macro "RGENGC_THREEGEN" enables/disables this feature, and
  turned off as default because there are several problems.
  (1) Failed sometimes (Heisenbugs).
  (2) Performance down.
      Especially on write barriers. We need to detect Young or Old
      object by oldgen_bitmap. It is slower than checking flags.
  To evaluate this feature on more applications, I commit this patch.
  Reports are very welcome.
  This patch includes some refactoring (renaming names, etc).
* include/ruby/ruby.h: catch up 3gen GC.
* .gdbinit: fix to show a prompt "[PROMOTED]" for promoted objects.

* gc.c (GC_MALLOC_LIMIT_MAX): fix default value 512MB -> 384MB.
  512MB is huge.

* gc.c: add support to estimate increase of oldspace memory usage.
  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.
