According to MSVC manual (*1), cl.exe can skip including a header file
when that:
- contains #pragma once, or
- starts with #ifndef, or
- starts with #if ! defined.
GCC has a similar trick (*2), but it acts more stricter (e. g. there
must be _no tokens_ outside of #ifndef...#endif).
Sun C lacked #pragma once for a looong time. Oracle Developer Studio
12.5 finally implemented it, but we cannot assume such recent version.
This changeset modifies header files so that each of them include
strictly one #ifndef...#endif. I believe this is the most portable way
to trigger compiler optimizations. [Bug #16770]

*2: https://gcc.gnu.org/onlinedocs/cppinternals/Guard-Macros.html
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
Looking at the list of symbols inside of libruby-static.a, I found
hundreds of functions that are defined, but used from nowhere.
There can be reasons for each of them (e.g. some functions are
specific to some platform, some are useful when debugging, etc).
However it seems the functions deleted here exist for no reason.
This changeset reduces the size of ruby binary from 26,671,456
bytes to 26,592,864 bytes on my machine.
For some reason symbols (or classes) are being overridden in trunk

* vm_insnhelper.c (vm_get_ev_const): add flag argument of
`rb_autoloading_value`.
* constant.h (rb_autoloading_value): moved the declaration from
vm_core.h for `rb_const_flag_t`. [ruby-core:85516] [Bug #14469]

* variable.c (rb_const_get_0): warn deprecated constant reference.
* variable.c (rb_mod_deprecate_constant): mark constants to be
warned as deprecated. [Feature #11398]

* variable.c: cleanup to use rb_const_lookup
* vm_insnshelper.c: ditto
This reduces casting and long lines. This should make it easier to
switch to alternatives to st for constant storage.

not raise an exception even when the constant is private. Instead,
rb_public_const_get_* and rb_public_const_defined_* are introduced,
which raise an exception when the referring constant is private.
see [ruby-core:32912].
* vm_insnhelper.c (vm_get_ev_const): use rb_public_const_get_* instead
of rb_const_get_* to follow the constant visibility when user code
refers a constant.
* test/ruby/test_marshal.rb (test_marshal_private_class): add a test.
This test had failed because of incompatibility of rb_const_get.

vm_insnhelper.c: use struct rb_constant_entry_t as entry of
RCLASS_CONST_TBL. RCLASS_CONST_TBL has contained VALUE of constant
directly. Now instead rb_const_entry_t is contained in
RCLASS_CONST_TBL, rb_const_entry_t is managed by malloc, and
have not only the value itself but also visibility flag.
This is another preparation for private constant (see
[ruby-dev:39685][ruby-core:32698]).
