avoid duplicated check of size.
* gc.c (ruby_xmalloc2): added to keep separate layers.
* include/ruby/ruby.h (rb_alloc_tmp_buffer2): added to check
the size more statically.

used by objspace_xmalloc and objspace_xcalloc.
objspace_xmalloc introduces its own check in this commit.
objspace_xcalloc checks with xmalloc2_size (ruby_xmalloc2_size).
* gc.c (objspace_xmalloc0): common xmalloc function.
* gc.c (objspace_xmalloc): introduce its own size check.
* gc.c (objspace_xmalloc2): separated from ruby_xmalloc2 to clarify
the layer who has the responsibility to check the size.
* gc.c (objspace_xrealloc): remove duplicated size check.
* gc.c (ruby_xmalloc2): use objspace_xmalloc2.
* include/ruby/ruby.h (ruby_xmalloc2_size): follow the size limit
as SSIZE_MAX. Note that ISO C says size_t is unsigned integer.

RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2
RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65
These values are same as Ruby 2.0.0.
This change cause GC counts.
However, generational GC reduced each (minor) GC time and
increase memory locality. So that not so big impact on my
benchmarking results.
(surprizingly, this fix speed up programs on some cases)
You can change these values by environment variables
if you feel wrong.

And also take an accept_zero flag which allow to accept zero
even if lower_bound is set.
* gc.c (ruby_gc_set_params): fix parameters.
RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO set 0.9 as *lower_bound*, so that
it should be upper_bound.
Set RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO as lower bound.
Also set lower/upper bound of RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO to
RUBY_GC_HEAP_FREE_SLOTS_MIN/MAX_RATIO.

Introduce new environement variable
GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the ratio
of additional memory.
Before this change, we add pages with the following formula
(when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO):
next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR
This addition can allocate too much.
With this change, we increase pages to satisfy the following formula:
next_free_slots = next_total_slots * goal_ratio
where
next_free_slots = free_slots + adding_slots
next_total_slots = total_slots + adding_slots.
If you want to prepare many free slots, increase this ratio.
If this variable is 0, then simply multiply
RUBY_GC_HEAP_GROWTH_FACTOR.
* gc.c (get_envparam_double): enable to accept 0.

Before this change, heap_pages_min_slots are calculated at the
beggining sweeping phase. And this value is used at the end of
*next* marking phase.
To simplify it, we use this value at the end of this marking phase.
It means that we don't need to store this value as global state.
Also heap_pages_max_slots is calculated at the begging of sweeping
phase and used at the end of sweeping phase.
To simplify this logic, we introduced new global value
heap_pages_freeable_pages it means extra pages count we can free.
gc_sweep_step() checks this value and moves empty pages to tomb_heap
not more than this value.
Because of this fix, heap_pages_swept_slots is no longer needed.
* gc.c (rb_objspace_t::heap_pages): restruct the objspace global
status.
remove the following fileds
* swept_slots (and heap_pages_swept_slots)
* min_free_slots (and heap_pages_min_free_slots)
* max_free_slots (and heap_pages_max_free_slots)
And add the following filed.
* freeable_pages (and heap_pages_freeable_pages)
* gc.c (heap_pages_free_unused_pages): unlink tomb heap pages
because tomb heap should have only freeable pages.
* gc.c (heap_extend_pages): add parameters for future extension.

* RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO:

allow to free pages when free slots is greater thatn
