Bugfixes: for Get(), don't hold mutex while writing log.
- Fix bug in Get: when it triggers a compaction, it could sometimes
mark the compaction with the wrong level (if there was a gap
in the set of levels examined for the Get).
- Do not hold mutex while writing to the log file or to the
MANIFEST file.
Added a new benchmark that runs a writer thread concurrently with
reader threads.

- Fixed race in optimized Get. It should have been using the
pinned memtables, not the current memtables.
