9f60791a04 * vm_core.h: revisit the structure of frame, block and env.
[Bug ]

  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 ] for more details.

5e8a147480 * method.h: introduce rb_callable_method_entry_t to remove
rb_control_frame_t::klass.
  [Bug ], [Bug ]
  rb_method_entry_t data belong to modules/classes.
  rb_method_entry_t::owner points defined module or class.
    module M
      def foo; end
    end
  In this case, owner is M.
  rb_callable_method_entry_t data belong to only classes.
  For modules, MRI creates corresponding T_ICLASS internally.
  rb_callable_method_entry_t can also belong to T_ICLASS.
  rb_callable_method_entry_t::defined_class points T_CLASS or
  T_ICLASS.
  rb_method_entry_t data for classes (not for modules) are also
  rb_callable_method_entry_t data because it is completely same data.
  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
  For example, there are classes C and D, and incldues M,
    class C; include M; end
    class D; include M; end
  then, two T_ICLASS objects for C's super class and D's super class
  will be created.
  When C.new.foo is called, then M#foo is searcheed and
  rb_callable_method_t data is used by VM to invoke M#foo.
  rb_method_entry_t data is only one for M#foo.
  However, rb_callable_method_entry_t data are two (and can be more).
  It is proportional to the number of including (and prepending)
  classes (the number of T_ICLASS which point to the module).
  Now, created rb_callable_method_entry_t are collected when
  the original module M was modified. We can think it is a cache.
  We need to select what kind of method entry data is needed.
  To operate definition, then you need to use rb_method_entry_t.
  You can access them by the following functions.
  * rb_method_entry(VALUE klass, ID id);
  * rb_method_entry_with_refinements(VALUE klass, ID id);
  * rb_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
  To invoke methods, then you need to use rb_callable_method_entry_t
  which you can get by the following APIs corresponding to the
  above listed functions.
  * rb_callable_method_entry(VALUE klass, ID id);
  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
  returns rb_callable_method_entry_t.
  You can check a super class of current method by
  rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
  rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
  rb_callable_method_entry_t data.
  We need to consider abotu this field again because it is only
  active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
  defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
  rb_callable_method_t has all information.
* vm_core.h: remove several fields.
  * rb_control_frame_t::klass.
  * rb_block_t::klass.
  And catch up changes.
* eval.c: catch up changes.

* method.h:  Now, all method entries has own independent method
  definititons. Strictly speaking, this change is not essential,
  but for future changes.
  * rb_method_entry_t::flag is move to rb_method_definition_t::flag.
  * rb_method_definition_t::alias_count is now
    rb_method_definition_t::alias_count_ptr, a pointer to the counter.
* vm_core.h, vm_insnhelper.c (rb_vm_frame_method_entry) added to

5c8c88a3e9 cont.c: Optimize fiber_switch callees
Remove some unnecessary VALUE/struct conversions and aggressively inline
functions used during fiber_switch. Either of these changes alone does

0bd492c6bf cont.c: Code cleanup in fiber_switch/fiber_store
Defragment code blocks depending on FIBER_USE_NATIVE in order to make
the control flow (which is already non-trivial due to nonlocal jumps) in
each case more comprehensible.

Remove some unreachable code from fiber_switch (we've already excluded
the case (th->fiber == fibval) at the start of the function).

Remove call to rb_fiber_current which happened a few lines after
accessing GET_THREAD()->fiber directly (so if that's ever 0 we're
already screwed).

6f6238a70c cont.c: Remove unused prev_fiber/next_fiber fields
They were added in r19890 (8a0d53a), with the explanation that it's a
double linked list of fibers in the same thread, but without any code
using them.

  (fiber_link_join, fiber_link_remove): remove functions
  (fiber_free, fiber_init, root_fiber_alloc):

	  Introdule ensure stack.

	* hash.c : New function for rollback ensure, and register it to
	  ensure-rollback relation table. [ruby-dev:47803] [Bug ]

	Ensure Rollback Mechanism:
	A rollback's function is a function to rollback a state before ensure's
	function execution.
	When the jump of callcc is across the scope of rb_ensure,
	ensure's functions and rollback's functions are executed appropriately
	for keeping consistency.

	Current API is unstable, and only internal use.

	ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
	This API create relation ensure's function to rollback's function.
	By registered rollback's function, it is executed When jumpping into
	corresponding rb_ensure scope.

d1674ef67b * gc.c: add support to estimate increase of oldspace memory usage.
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.
