* dns_journal_next() leaves the read point in the journal after the
transaction header so journal_seek() should be inside the loop.
* we need to recover from transaction header inconsistencies
Additionally when correcting for <size, serial0, serial1, 0> the
correct consistency check is isc_serial_gt() rather than
isc_serial_ge(). All instances updated.
