* fix default vaues:
GC_MALLOC_LIMIT_GROWTH_FACTOR
GC_MALLOC_LIMIT: 8MB -> 16MB
GC_MALLOC_LIMIT_MAX: 384MB -> 32MB
* algorithm of malloc_limit increment.
if (malloc_increase < malloc_limit) {
next_malloc_limit = malloc_limit * factor
if (malloc_limit > malloc_limit_max) {
malloc_limit = malloc_increase
}
}
This algorithm change malloc_limit from
16MB -> 32MB slowly.
If malloc_limit exceeds malloc_limit_max, then
increase with malloc_increase.

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.

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.
