Title: Use pool allocation for st_table

Usage of specialized pool allocation for st_table, st_table_entry and st_table.bins of smallest size.

It gives up to 20% peak performance improvement (assuming C extension like in test below) and up to 4% in average (assuming rails application). Also it gives considerable memory footprint reduction.

Performance testing is here https://gist.github.com/1626602
