vm_core.h but turn on by RGENGC_CHECK_MODE.

if RUBY_DEVEL.

newline, as gc_report_body does not append it.

* vm_core.h: rename absolute_path to realpath because it is expected name.
external APIs (#absolute_path methods) are remained.
* vm_core.h: remove rb_iseq_location_struct::path and
rb_iseq_location_struct::absolute_path and introduce pathobj.
if given path equals to given absolute_path (and most of case
it is true), pathobj is simply given path String. If it is not same,
pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.
This size optimization reduce 8 bytes and
sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes
on 64bit CPU.
To support this change, the following functions are introduced:
* pathobj_path() (defined in vm_core.h)
* pathobj_realpath() (ditto)
* rb_iseq_path() (decl. in vm_core.h)
* rb_iseq_realpath() (ditto)
* rb_iseq_pathobj_new() (ditto)
* rb_iseq_pathobj_set() (ditto)
* vm_core.h (rb_binding_t): use pathobj instead of path. If binding
is given at eval methods, realpath (absolute_path) was caller's
realpath. However, they should use binding's realpath.

obj_ary_embed: freed count of Arrays they don't have extra buff.
obj_obj_ptr: freed count of Objects (T_OBJECT) they have extra buff.
obj_obj_embed: freed count of Objects they don't have extra buff.

Use PRIuSIZE instead of PRIdSIZE. This fixes the exception message shown
on too large xmalloc2. This commit also fixes other incorrect use of
PRIdSIZE in other functions; though most of them are debug print.

because there are no method defined.
* vm_core.h: remove the following definitions.
* rb_cEnv decl.
* GetEnvPtr() because Env is no longer T_DATA object.

[Bug #12628]
This patch introduce many changes.
* Introduce concept of "Block Handler (BH)" to represent
passed blocks.
* move rb_control_frame_t::flag to ep[0] (as a special local
variable). This flags represents not only frame type, but also
env flags such as escaped.
* rename `rb_block_t` to `struct rb_block`.
* Make Proc, Binding and RubyVM::Env objects wb-protected.
Check [Bug #12628] for more details.

volatile to ensure not to be clobbered by longjmp.

I expected to inline this function implicitly at the loop
(ex: marking T_ARRAY objects) but sometimes it remains as
normal call.

protecting for each finalizer.

Before this patch, we only set mark bit for the VM object and

and define CONSTFUNC and PUREFUNC if available.
Note that I don't add those options as default because
it still shows many false-positive (it seems not to consider
longjmp).
* vm_eval.c (stack_check): get rb_thread_t* as an argument
to avoid duplicate call of GET_THREAD().

the current thread global variable.

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.
