  NMS-20269: Make source file_order unique and safe under concurrent changes

file_order is now enforced unique by a deferrable constraint, with existing
duplicates repaired on upgrade. New sources are allocated their position and
eventconf.xml uploads are renumbered inside a serialized transaction, and a
source's events are rewritten under a lock on the source row, so concurrent
creates, uploads and appends can no longer produce duplicate positions.
