Use pg_trigger_depth to avoid re-trigger in update (#1708 )

Some of the `update_osm_${LAYER}`-functions, which are executed by triggers on updates, execute an UPDATE statement on the same tables that have these triggers. This causes the trigger functions `flag` and `store` to run multiple times for one record. 

For instance, if I add log in the trigger functions and run an INSERT on `osm_housenumber_point`, this output is generated:  

```
NOTICE:  Store
NOTICE:  Flag
NOTICE:  Refresh housenumber
NOTICE:  Flag
NOTICE:  Store
NOTICE:  Flag
INSERT 0 1
```

If we limit the triggers from executing if they are called from another trigger using `pg_trigger_depth() < 1`, the triggers will only be triggered once per record:

```
NOTICE:  Store
NOTICE:  Flag
NOTICE:  Refresh housenumber
INSERT 0 1
```

This will prevent redunant executions and might improve update performance.
