Siying Dong f040e536e4 [RocksDB Performance Branch] A more customized index in PlainTableReader 
Summary:
PlainTableReader to use a more customized hash table. This patch assumes the SST file is smaller than 2GB:
(1) Every bucket uses 32-bit integer
(2) no key is stored in bucket
(3) use the first bit of the bucket value to distinguish it points to the file offset or a second level index.
This index schema fits the use case that most of prefixes have very small number of keys

Test Plan: plain_table_db_test
