* parse.y (TOKEN2ID): add macro which maps static tokens to IDs.
* template/id.h.tmpl (TOKEN2*ID, DEFINE_*ID_FROM_TOKEN): separate
into macros, token to ID mapping and enum definitions.

* symbol.c (op_tbl): remove non-regular symbols.
* symbol.c (global_symbols): start from the next of the preserved
ID.
* symbol.c: (rb_id2str): op_tbl does not exceed tLAST_OP_ID.

See this ticket about Symbol GC.
* include/ruby/ruby.h:
Declare few functions.
* rb_sym2id: almost same as old SYM2ID but support dynamic symbols.
* rb_id2sym: almost same as old ID2SYM but support dynamic symbols.
* rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not
pin down a dynamic symbol.
Declare a new struct.
* struct RSymbol: represents a dynamic symbol as object in
Ruby's heaps.
Add few macros.
* STATIC_SYM_P: check a static symbol.
* DYNAMIC_SYM_P: check a dynamic symbol.
* RSYMBOL: cast to RSymbol
* gc.c: declare RSymbol. support T_SYMBOL.
* internal.h: Declare few functions.
* rb_gc_free_dsymbol: free up a dynamic symbol. GC call this
function at a sweep phase.
* rb_str_dynamic_intern: convert a string to a dynamic symbol.
* rb_check_id_without_pindown: not pinning function.
* rb_sym2id_without_pindown: ditto.
* rb_check_id_cstr_without_pindown: ditto.
* string.c (Init_String): String#intern and String#to_sym use
rb_str_dynamic_intern.
* template/id.h.tmpl: use LSB of ID as a flag for determining a
static symbol, so we shift left other ruby_id_types.
* string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to
avoid pinning.
* load.c: use xx_without_pindown function at creating temporary ID
to avoid pinning.
* object.c: ditto.
* sprintf.c: ditto.
* struct.c: ditto.
* thread.c: ditto.
* variable.c: ditto.
* vm_method.c: ditto.

* .gdbinit (rp_id): show ID type.
* template/id.h.tmpl (ruby_id_types): make enum for debugger.

* defs/id.def: support for other scope IDs,
ID_{INSTANCE,GLOBAL,CONST,CLASS}.

* common.mk, defs/id.def, template/id.c.tmpl: generate id.c as well as id.h.

* template/id.h.tmpl (attr_ids): remove Bitblt and Answer which are no
longer predefined.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38185 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38155 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* template/id.h.tmpl, tool/id2token.rb: make id.h independent from
parse.h, and make parse.c dependent on it instead.
