This covers v1 inboxes, as well.  We also guard the execution
since "PRAGMA optimize" was only introduced in SQLite 3.18.0

1/5 may affect some users
3/5 quiets things down for users on SQLite <3.18
5/5 is a good usability fix for me

Eric Wong (5):
  extindex: flush pending reindex before unref
  lei/store: use remove_doc to save some LoC
  index: optimize after all SQLite DB commits
  doc: relnotes: note some recent improvements
  lei up --all: show output for warnings
