* include/ruby/intern.h: declare rb_hash_tbl.

* include/ruby/ruby.h (RHash): delay st_table allocation.
  rename tbl field to ntbl to detect direct reference to the st_table
  as a compile error.
  (RHASH_TBL): abstract accessor defined.
  (RHASH_ITER_LEV): ditto.
  (RHASH_IFNONE): ditto.
  (RHASH_SIZE): ditto.
  (RHASH_EMPTY_P): ditto.

* hash.c: delay st_table allocation.

* gc.c: replace tbl by ntbl.

* array.c: replace direct field accessor by abstract field accessor
  such as RHASH(hash)->tbl to RHASH_TBL(hash).

* marshal.c: ditto.

* insns.def: ditto.

* ext/iconv/iconv.c: ditto.

* ext/json/ext/generator/generator.c: ditto.

* ext/json/ext/parser/parser.c: ditto.

* ext/syck/rubyext.c: ditto.
