      Bug#13006367 62487: innodb takes 3 minutes to clean up the adaptive
      hash index at shutdown
      
      btr_search_disable(): Just drop the entire adaptive hash index,
      without dropping every record separately.
      
      buf_pool_clear_hash_index(): Renamed and simplified from
      buf_pool_drop_hash_index(). Set block->index = NULL for every block in
      the buffer pool. Do not release the btr_search_latch. The caller will
      have to adjust other data structures.
      
      Remove block->is_hashed. It is redundant, should be always equal to
      block->index != NULL.
      
      Remove btr_search_fully_disabled, btr_search_enabled_mutex, and
      SYNC_SEARCH_SYS_CONF. We drop the AHI in one pass, without releasing
      the btr_search_latch in between.
      
      Replace void* with const rec_t* and add assertions on btr_search_latch
      and btr_search_enabled to ha0ha.h, ha0ha.ic, ha0ha.c.
      
      page_set_max_trx_id(): Ignore the adaptive hash index. I forgot to
      push this in rb:750.
      
      btr0sea.c: Always after acquiring btr_search_latch, check for
      block->index==NULL or !btr_search_enabled. We can now set
      block->index=NULL while only holding btr_search_latch in exclusive
      mode. Always acquire btr_search_latch before reading block->index,
      except in shortcuts when testing for block->index == NULL.
      
      ha_clear(), ha_search(): Unused function, remove.
      
      buf_page_peek_if_search_hashed(): Remove. This function may avoid
      latching a page at the cost of doing a duplicate buf_pool->page_hash
      lookup.
