Change the journal_mode pragma so that it always returns the current journal mode, even on a failed attempt to change the journal mode. Allow the journal mode to be changed as long as there is not a pending transaction. Ticket #3811. (CVS 6526) (check-in: 419e320ae5 user: drh tags: trunk)

Clarify the documentation to make it clear that sqlite3_interrupt() does not effect new SQL statements that are started after the running statement count reaches zero. Ticket #3815. (CVS 6524) (check-in: 3182e8bf69 user: drh tags: trunk)

#
# Verify that journal_mode=OFF works as long as it occurs before the first
# transaction, even if locking_mode=EXCLUSIVE is enabled.  The behavior if
# journal_mode is changed after the first transaction is undefined and hence
# untested.
