A different fix to [fc62af4523]. When changing from journal_mode=PERSIST or TRINCATE to some other rollback mode, delete the journal file only if a RESERVED lock can be obtained on the database file first. check-in: b9b11855 user: dan tags: experimental

Fix the tkt-fc62af4523.test to work around non-randomness of the randomblob() function when in testing mode. check-in: 7c3a86b9 user: drh tags: trunk
