Insert the first two strings in the hash table after a flush. This allows deflate to generate the same output when continuing after a Z_SYNC_FLUSH vs. using deflateSetDictionary() after a Z_FULL_FLUSH or a deflateReset(). It also slightly improves compression when flushing by providing two more strings to possibly match at the start of the new block.
