Centralize locking of all chains of the tdb; rename _tdb_lockall to tdb_allrecord_lock and _tdb_unlockall to tdb_allrecord_unlock, and tdb_brlock_upgrade to tdb_allrecord_upgrade. Then we use this in the transaction code. Unfortunately, if the transaction code records that it has grabbed the allrecord lock read-only, write locks will fail, so we treat this upgradable lock as a write lock, and mark it as upgradable using the otherwise-unused offset field. One subtlety: now the transaction code is using the allrecord_lock, the tdb_release_extra_locks() function drops it for us, so we no longer need to do it manually in _tdb_transaction_cancel.
