卜部昌平 4ff3f20540 add #include guard hack
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]

卜部昌平 5e22f873ed decouple internal.h headers
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).

ko1 c35ff11ae5 * id_table.h: introduce ID key table.
[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.
  * internal.h: use id_table for method tables.
  * class.c, gc.c, marshal.c, vm.c, vm_method.c: ditto.

normal 442b77e721 symbol.h: memoize hashval for RSymbol
This speeds up the hash function for dynamic symbols.
[ruby-core:70129] [Bug #11396], nearly up to Ruby 2.1 levels

Power-of-two hash sizing [Feature #9425] speeds up cases where we
have a good hash, but this means we can no longer hide behind weak
hashes.  Unfortunately, object IDs do not hash well, but we may
use the extra space in the RSymbol struct to memoize the hash value.

Further optimizations should be possible.  For now, the st.c APIs
force us to calculate rb_str_hash redundantly at dsym registration.

* symbol.h (struct RSymbol): add hashval field
* symbol.c (dsymbol_alloc): setup hashval field once
* hash.c (rb_any_hash): return RSymbol->hashval directly
* common.mk: hash.o depends on symbol.h
