卜部昌平 c37a357c13 include what you use. 
This reverts commit 443389effc.
This reverts commit d94960f22e.

Inclusion of header files must be explicit.  Every file shall directly
include what is necessary.

https://github.com/include-what-you-use/include-what-you-use says:

> When every file includes what it uses, then it is possible to edit any
> file and remove unused headers, without fear of accidentally breaking
> the upwards dependencies of that file. It also becomes easy to
> automatically track and update dependencies in the source code.

Though we don't use iwyu itself, the principle quoted above is a good
thing that we can agree.

Now that include guards were added to every and all of the headers
inside of our project this changeset does not increase compile time, at
least on my machine.

* @file
* @author Ruby developers <ruby-core@ruby-lang.org>
* @copyright This file is a part of the programming language Ruby.
* Permission is hereby granted, to either redistribute and/or
* modify this file, provided that the conditions mentioned in the
* file COPYING are met. Consult the file for details.
* @warning Symbols prefixed with either `RUBY3` or `ruby3` are
* implementation details. Don't take them as canon. They could
* rapidly appear then vanish. The name (path) of this header file
* is also an implementation detail. Do not expect it to persist
* at the place it is now. Developers are free to move it anywhere
* anytime at will.
* @note To ruby-core: remember that this header can be possibly
* recursively included from extension libraries written in C++.
* Do not expect for instance `__VA_ARGS__` is always available.
* We assume C99 for ruby itself but we don't assume languages of
* extension libraries. They could be written in C++98.
* @brief Function overloads to issue warnings around #ANYARGS.
*
* For instance ::rb_define_method takes a pointer to #ANYARGS -ed functions,
* which in fact varies 18 different prototypes. We still need to preserve
* #ANYARGS for storages but why not check the consistencies if possible. With
* those complex macro overlays defined in this header file, use of a function
* pointer gets checked against the corresponding arity argument.
*
* ### Q&A ###
*
* - Q: Where did the magic number "18" came from in the description above?
*
* - A: Count the case branch of `vm_method.c:call_cfunc_invoker_func()`. Note
* also that the 18 branches has lasted for at least 25 years. See also
* commit 200e0ee2fd3c1c006c528874a88f684447215524.
*
* - Q: What is this `__weakref__` thing?
*
* - A: That is a kind of function overloading mechanism that GCC provides. In
* this case for instance `rb_define_method_00` is an alias of
* ::rb_define_method, with a strong type.
*
* - Q: What is this `__transparent_union__` thing?
*
* A: That is another kind of function overloading mechanism that GCC
* provides. In this case the attributed function pointer is either
* `VALUE(*)(int,VALUE*,VALUE)` or `VALUE(*)(int,const VALUE*,VALUE)`.
*
* This is better than `void*` or #ANYARGS because we can reject all other
* possibilities than the two.
*
* - Q: What does this #rb_define_method macro mean?
*
* - A: It selects appropriate alias of the ::rb_define_method function,
* depending on the last (arity) argument.
*
* - Q: Why the special case for ::rb_f_notimplement ?
*
* - A: Function pointer to ::rb_f_notimplement is special cased in
* `vm_method.c:rb_add_method_cfunc()`. That should be handled by the
* `__builtin_choose_expr` chain inside of #rb_define_method macro
* expansion. In order to do so, comparison like
* `(func == rb_f_notimplement)` is inappropriate for
* `__builtin_choose_expr`'s expression (which must be a compile-time
* integer constant but the address of ::rb_f_notimplement is not fixed
* until the linker). Instead we are using
* `__builtin_types_compatible_p`, and in doing so we need to distinguish
* ::rb_f_notimplement from others, by type.
