[Feature #11420]
This table only manage ID->VALUE table to reduce overhead of st.
Some functions prefixed rb_id_table_* are provided.
* id_table.c: implement rb_id_table_*.
There are several algorithms to implement it.
Now, there are roughly 4 types:
* st
* array
* hash (implemented by Yura Sokolov)
* mix of array and hash
The macro ID_TABLE_IMPL can choose implementation.
You can see detailes about them at the head of id_table.c.
At the default, I choose 34 (mix of list and hash).
This is not final decision.
Please report your suitable parameters or
your data structure.
* symbol.c: introduce rb_id_serial_t and rb_id_to_serial()
to represent ID by serial number.

All contents of previous rb_iseq_t is in rb_iseq_t::body.
Remove rb_iseq_t::self because rb_iseq_t is an object.
RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
So RubyVM::ISeq.of(something) method returns different wrapper
objects but they point the same T_IMEMO/iseq object.
This patch is big, but most of difference is replacement of
iseq->xxx to iseq->body->xxx.
(previous) rb_iseq_t::compile_data is also located to
rb_iseq_t::compile_data.
It was moved from rb_iseq_body::compile_data.
Now rb_iseq_t has empty two pointers.
I will split rb_iseq_body data into static data and dynamic data.
* compile.c: rename some functions/macros.
Now, we don't need to separate iseq and iseqval (only VALUE).

rb_control_frame_t::klass.
[Bug #11278], [Bug #11279]
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.

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

struct method_table_wrapper was introduced to avoid duplicate marking
for method tables.
For example, `module M1; def foo; end; end` make one method table
(mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
Classes C1 and C2 includes M1, then two T_ICLASS objects are created
and they points mtbl too. In this case, three objects (one T_MODULE
and two T_ICLASS objects) points same mtbl. On marking phase, these
three objects mark same mtbl. To avoid such duplication, struct
method_table_wrapper was introduced.
However, created two T_ICLASS objects have same or shorter lifetime
than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
not from T_ICLASS objects. This patch tries marking only from M1.
Note that one `Module#prepend` call creates two T_ICLASS objects.
One for refering to a prepending Module object, same as
`Module#include`. We don't nedd to care this T_ICLASS.
One for moving original mtbl from a prepending class. We need to
mark such mtbl from this T_ICLASS object. To mark the mtbl,
we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
class `klass`.
* class.c: ditto.
* eval.c (rb_using_refinement): ditto.
* gc.c: ditto.
* include/ruby/ruby.h: define m_tbl directly. The definition of
struct RClass should be moved to (srcdir)/internal.h.
* method.h: remove decl of rb_free_m_tbl_wrapper().
* object.c: use RCLASS_M_TBL() directly.

* variable.c (rb_tmp_class_path): defer making temporary class
path string.
* variable.c (rb_search_class_path): search class path or return
Qnil or Qfalse if unnamed, not creating a temporary path.
