Cheng Chang 89cc06b3e7 Add a new db_map_fuzzer (#7762)
Summary:
Execute randomly generated operations on both a DB and a std::map,
then reopen the DB and make sure that iterating the DB produces the
same key-value pairs as iterating through the std::map.

davkor ba2a3bf092 OSS-Fuzz integration and db_fuzzer (#7674)
Summary:
This PR adds a fuzzer to the project and infrastructure to integrate Rocksdb with OSS-Fuzz. OSS-Fuzz is a service run by Google that performs continuous fuzzing of important open source projects. The LevelDB project is also in being fuzzed by OSS-Fuzz (https://github.com/google/oss-fuzz/tree/master/projects/leveldb). Essentially, OSS-Fuzz will perform the fuzzing for you and email you bug reports, coverage reports etc. All we need is a set of email addresses that will receive this information.

For cross-referencing, the PR that adds the OSS-Fuzz logic is here: https://github.com/google/oss-fuzz/pull/4642

The `db_fuzzer` of the PR performs stateful fuzzing of Rocksdb by calling a sequence of Rockdb's APIs with random input in each fuzz iteration. Each fuzz iteration, thus, creates a new instance of Rocksdb and operates on this given instance. The goal is to test diverse states of Rocksdb and ensure no state lead to error conditions, e.g. memory corruption vulnerabilities.

The fuzzer is similar (although more complex) to the fuzzer that is currently being used to analyse Leveldb (https://github.com/google/oss-fuzz/blob/master/projects/leveldb/fuzz_db.cc)

Cheng Chang 699411b2ca Fuzzing RocksDB (#7685)
Summary:
This is the initial PR to support adding fuzz tests to RocksDB.
It includes the necessary build infrastructure, and includes an example fuzzer.
There is also a README serving as the tutorial for how to add more tests.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7685

Test Plan: Manually build and run the fuzz test according to README.
