Joey Hess 9dfe03dbcd Improve shutdown due to --time-limit, especially for fsck
* Perform a clean shutdown when --time-limit is reached.
  This includes running queued git commands, and cleanup actions normally
  run when a command is finished.
* fsck: Commit incremental fsck database when --time-limit is reached.
  Previously, some of the last files fscked did not make it into the
  database when using --time-limit.

Note that this changes Annex.addCleanup hooks, to run after --time-limit
expires. Fsck was using such a hook to clean up after a
--incremental-schedule, and that shouldn't run when --time-limit exipires
it. So, instead, moved that cleanup code to be run by cleanupIncremental.
Resulted in some data type juggling.
