lib/db, lib/model: Add sequence->deviceKey to db for sending indexes (#4906)

Browse Source 
Instead of walking and unmarshalling the entire db and sorting the resulting
file infos by sequence, add store device keys by sequence number in the
database. Thus only the required file infos need be unmarshalled and are already
sorted by index.
