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.

Please refer this ticket for details.
This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().

fstrings refered by static symbols and pinned dynamic symbols
are registerd by rb_gc_register_mark_object().
frstring refered by dynamic symbols (not pinned symbols)
are refered from global_symbols.dsymbol_fstr_hash (Hash object).
Note that fstrings refered from dynamic symbols must live loger
than symbol objects themselves because rb_gc_free_dsymbol() uses
fstring to remove from symbol tables.
This is why we can not mark fstrings from dynamic symbols.
This technique reduces root objects for GC marking.

(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.

Without this option, some application consumes huge memory.

* RUBY_GC_HEAP_OLDSPACE_GROWTH_FACTOR (default 1.2)
* gc.c (initial_malloc_limit): rename to initial_malloc_limit_min.

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.
