Support resuming if successful and if normal failure (but not failure to rename)
Remove unused rename failed code. The rename happens in the FileBucket and it will call us with a bucket error if we fail.
Migration for failure case where we failed to rename (this doesn't exist in the new code)
Fix bug in migration
Logging
Delete old database when migrated.
Don't create an empty database
Slightly quieter if no database
Remove defrag support
Don't migrate from encrypted to plaintext or vice versa, and don't create a new database.
Missing files
Fix NPE when migrating downloads to temp space
Fix filename
Get rid of database encrypted flag
Remove alerts for not enough space for auto change crypt
Avoid NPE
Fix hasDatabase()
Remove autoChangeDatabaseEncryption, config option and warnings
Set up keys earlier on, regardless of whether we actually need them (mostly we will)
Checkpoint ASAP after migrating.
