 -Fix at r6680

 ST_Value now return NULL for nodata value and ST_SetValue accept NULL
 values (if there is a nodata value in the band).

 ST_Value accept a boolean parameter which, when set to false, have the
 function to return nodata values as their true value instead of null.

 Some plpgsql scripts will have to be updated.
