Introduce snapshot recycling.

When snapshotting large file systems whose contents do not change much between
snapshots, we end up removing large amounts of files just to recreate (hard
links to) most of them afterwards. This patch changes snapshot creation so that
outdated, redundant and orphaned snapshots are reused as the basis for new
snapshots. Only if no existing snapshot is suitable for recycling, a new one is
created.
