check_and_write_node

  $store->check_and_write_node( node     => $node,
                checksum => $checksum,
                                %other_args );

Locks the node, verifies the checksum, calls write_node_post_locking with all supplied arguments, unlocks the node. Returns the version of the updated node on successful writing, 0 if checksum doesn't match, -1 if the change was not applied, croaks on error.

Note: Uses MySQL's user level locking, so any locks are released when the database handle disconnects. Doing it like this because I can't seem to get it to work properly with transactions.
