Called for (some) API query modules before a database query is made. WARNING: It would be very easy to misuse this hook and break the module! Any joins added *must* join on a unique key of the target table unless you really know what you're doing. An API query module wanting to use this hook should see the ApiQueryBase::select() and ApiQueryBase::processRow() documentation.
