costan 0db30413a4 leveldb: Add more thread safety annotations. After this CL, all classes with Mutex members should be covered by annotations. Exceptions are atomic members, which shouldn't need locking, and DBImpl members that cause errors when annotated, which will be tackled separately. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=190260865		6 lat temu
