rename li_table->ar_table (and related names).

Browse source 
* internal.h: rename the following names:
  * li_table -> ar_table. "li" means linear (from linear search),
    but we use the word "array" (from data layout).
  * RHASH_ARRAY -> RHASH_AR_TABLE. AR_TABLE is more clear.
  * rb_hash_array_* -> rb_hash_ar_table_*.
  * RHASH_TABLE_P() -> RHASH_ST_TABLE_P(). more clear.
  * RHASH_CLEAR() -> RHASH_ST_CLEAR().

* hash.c: rename "linear_" prefix functions to "ar_" prefix.

* hash.c (linear_init_table): rename to ar_alloc_table.

* debug_counter.h: rename obj_hash_array to obj_hash_ar.
