Yi Wu	d1b74b0c82	WritePrepared Txn: Compaction/Flush Summary: Update Compaction/Flush to support WritePreparedTxnDB: Add SnapshotChecker which is a proxy to query WritePreparedTxnDB::IsInSnapshot. Pass SnapshotChecker to DBImpl on WritePreparedTxnDB open. CompactionIterator use it to check if a key has been committed and if it is visible to a snapshot. In CompactionIterator: * check if key has been committed. If not, output uncommitted keys AS-IS. * use SnapshotChecker to check if key is visible to a snapshot when in need. * do not output key with seq = 0 if the key is not committed.
