benchmark store test for 1 billion 20 byte keys, 0-sized values

Note, the batch size is rather large (100000) in this test...

On my macbookpro, 16GB ram, SSD...

15 MB/sec write throughput to populate database with sequential 1B
items, and wait for persistence to complete.

56 MB/sec read throughput to sequentially scan through all 1B items
after a file reopen (and, OS cache is warm).

The benchmark test driver is single threaded.

$ go test -timeout=10h -bench=BenchmarkStoreBig -tags=benchmark_store_big
PASS
