clear counter at the beggining of every GC and
count promoted (infant->young) objects.
Some promotions (infant->young) are transition of promoting to old
objects. We should not count such promotions.
With this technique, we don't need to check young objects
at obj_free().

gc_verify_internal_consistency() counts all
- live objects
- young objects (if age2 promotion)
- old objects
in all pages and compares with objspace managing counters.

`int' but RVALUE_OLD_P() returns VALUE.

correctly.

Tomb heap pages are freed pages here, so expanding heap is
not required.

GC at realloc is not well maintained.
We need a time to make it safe.

Add a new (hidden) C-API to iterate objspace snapshot.
This API is not safe to call any C-APIs in a given callback
function. Be careful to use this C-API.

See this ticket about Symbol GC.
* include/ruby/ruby.h:
Declare few functions.
* rb_sym2id: almost same as old SYM2ID but support dynamic symbols.
* rb_id2sym: almost same as old ID2SYM but support dynamic symbols.
* rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not
pin down a dynamic symbol.
Declare a new struct.
* struct RSymbol: represents a dynamic symbol as object in
Ruby's heaps.
Add few macros.
* STATIC_SYM_P: check a static symbol.
* DYNAMIC_SYM_P: check a dynamic symbol.
* RSYMBOL: cast to RSymbol
* gc.c: declare RSymbol. support T_SYMBOL.
* internal.h: Declare few functions.
* rb_gc_free_dsymbol: free up a dynamic symbol. GC call this
function at a sweep phase.
* rb_str_dynamic_intern: convert a string to a dynamic symbol.
* rb_check_id_without_pindown: not pinning function.
* rb_sym2id_without_pindown: ditto.
* rb_check_id_cstr_without_pindown: ditto.
* string.c (Init_String): String#intern and String#to_sym use
rb_str_dynamic_intern.
* template/id.h.tmpl: use LSB of ID as a flag for determining a
static symbol, so we shift left other ruby_id_types.
* string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to
avoid pinning.
* load.c: use xx_without_pindown function at creating temporary ID
to avoid pinning.
* object.c: ditto.
* sprintf.c: ditto.
* struct.c: ditto.
* thread.c: ditto.
* variable.c: ditto.
* vm_method.c: ditto.

garbage_collect_with_gvl() here on non-ruby threads.
Should just ignore the malloc_increase.

This hopefully works on all platforms with malloc_usable_size.
This may also trigger bugs in places which did not expect GC, too;
so maybe some existing code will need RB_GC_GUARD.
