Summary: Code was always compressing L0 files written by a memtable flush when compression was enabled. Now this is done when min_level_to_compress=0 for leveled compaction and when universal_compaction_size_percent=-1 for universal compaction. Task ID: #3416472 Blame Rev: Test Plan: ran db_bench with compression options Revert Plan: Database Impact: Memcache Impact: Other Notes: EImportant: - begin *PUBLIC* platform impact section - Bugzilla: # - end platform impact - Reviewers: dhruba, igor, sdong Reviewed By: dhruba CC: leveldb Differential Revision: https://reviews.facebook.net/D14757
