  Log:
    support theap for T_HASH. [Feature #14989]
    
    * hash.c, internal.h: support theap for small Hash.
      Introduce RHASH_ARRAY (li_table) besides st_table and small Hash
      (<=8 entries) are managed by an array data structure.
      This array data can be managed by theap.
      If st_table is needed, then converting array data to st_table data.
    
      For st_table using code, we prepare "stlike" APIs which accepts hash value
      and are very similar to st_ APIs.
    
      This work is based on the GSoC achievement
      by tacinight <tacingiht at gmail.com> and refined by ko1.
