      These commits implement log compression to address WT-1359 . This does not currently include an option to checkpoint just the header.

      There are some fixes to existing code as well:
      – in block compression, if snappy compress returns a buf larger than the original, we'll use it! https://github.com/wiredtiger/wiredtiger/commit/428fa167621a8c64ee40429853f9d9c31f62df34
      – use time.sleep(0), not yield: https://github.com/wiredtiger/wiredtiger/commit/9058f6a54b7022d5346622c3656ef874676f5d10

      The second fix above now has some txn tests completing that used to return early. It may make the test suite run longer (20% longer for me).
