Summary: When we expand the range of keys for a level 0 compaction, we need to invoke ParentFilesInCompaction() only once for the entire range of keys that is being compacted. We were invoking it for each file that was being compacted, but this triggers an assertion because each file's range were contiguous but non-overlapping. I renamed ParentFilesInCompaction to ParentRangeInCompaction to adequately represent that it is the range-of-keys and not individual files that we compact in a single compaction run. Here is the assertion that is fixed by this patch. db_test: db/version_set.cc:585: void leveldb::Version::ExtendOverlappingInputs(int, const leveldb::Slice&, const leveldb::Slice&, std::vector<leveldb::FileMetaData*, std::allocator<leveldb::FileMetaData*> >*, int): Assertion `user_cmp->Compare(flimit, user_begin) >= 0' failed.
