ruby--ruby/id_table.h
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.
