Summary: This change adds two unit tests that would each catch the regression fixed in https://github.com/facebook/rocksdb/issues/9736 * TableMetaIndexKeys - detects any churn in metaindex block keys generated by SST files using standard db_test_util configurations. * BloomFilterCompatibility - this detects if any common built-in FilterPolicy configurations fail to read filters generated by another. (The regression bug caused NewRibbonFilterPolicy not to read filters from NewBloomFilterPolicy and vice-versa.) This replaces some previous tests that didn't really appear to be testing much of anything except basic data correctness, which doesn't tell you a filter is being used. Light refactoring in meta_blocks.cc/h to support inspecting metaindex keys. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9773 Test Plan: this is the test. Verified that 7.0.2 fails both tests and 7.0.3 passes. With backporting for intentional API changes in 7.0, 6.29 also passes.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
