Summary: Add a DB Property "rocksdb.estimate-table-readers-mem" to return estimated memory usage by all loaded table readers, other than allocated from block cache. Refactor the property codes to allow getting property from a version, with DB mutex not acquired. Test Plan: Add several checks of this new property in existing codes for various cases.

Summary: - Maintain a list of key-value pairs as vectors during Add operation. - Start building hash table only when Finish() is called. - This approach takes more time and space but avoids taking file_size, key and value lengths. - Rewrote cuckoo_table_builder_test I did not know about IterKey while writing this diff. I shall change places where IterKey could be used instead of std::string tomorrow. Please review rest of the logic.

Summary: Since we have enough memory to hold all primary keys loaded from spatial index, it is better if we first load all of them (store them in unordered_set for deduplication) and then query on primary key column family one by one. We need to dedup all IDs, so we'll end up storing all of them in memory even with the current approach.

Summary: I was bit by this when developing SpatialDB. In case all files are at level 0, CompactRange() will output the compacted files to level 0. This is not ideal, since read amp. is much better at level 1 and higher. Test Plan: Compacted data in SpatialDB, read manifest using ldb, verified that files are now at level 1 instead of 0.

Summary: Previously, builder.cc has a check for merge operator which prevents RocksDB from crash when reopening a DB w/o properly specifying the merge operator. However, currently we observed a memory leak on failing in RocksDB recovery. This diff removes such check and let it crash instead of causing memory leak for now before we have identified the real cause of the memory leak.

Summary: We now reads table properties in VersionSet::LogAndApply(), which requires options.db_paths to be set. But since ldb_cmd directly creates VersionSet without initialization db_paths, causing a seg fault. This patch fix it by initializing db_paths. log_and_apply_bench still shows segfault, because table cache is nullptr in VersionSet created. Test Plan: Run ldb dump_manifest which used to fail.

Summary: In block based table's hash index checking, when looking for a key that doesn't exist, there is a high chance that a false block is returned because of hash bucket conflicts. In this revision, another check is done to filter out some of those cases: comparing previous key of the block boundary to see whether the target block is what we are looking for. In a favored test setting (bloom filter disabled, 8 L0 files), I saw about 80% improvements. In a non-favored test setting (bloom filter enabled, files are all in L1, files are all cached), I see the performance penalty is less than 3%.
