/**
 * Function UpdateCopyOfZonesList
 * check a pick list to remove zones identical to their copies
 * and set the type of operation in picker (UR_DELETED, UR_CHANGED)
 * if an item is deleted, the initial values are retrievered,
 * because they can have changed in edition
 * @param aPickList = the main pick list
 * @param aAuxiliaryList = the list of deleted or added (new created) items after calculations
 * @param aPcb = the Board
 *
 * aAuxiliaryList is a list of pickers updated by zone algorithms:
 *  This list contains zones which were added or deleted during the zones combine process
 * aPickList :is a list of zones that can be modified (changed or deleted, or not modified)
 *  Typically, this is the list of existing zones on the layer of the edited zone,
 *  before any change.
 *  >> if the picked zone is not changed, it is removed from list
 *  >> if the picked zone was deleted (i.e. not found in board list), the picker is modified:
 *          its status becomes UR_DELETED
 *          the aAuxiliaryList corresponding picker is removed (if not found : set an error)
 *  >> if the picked zone was flagged as UR_NEW, and was after deleted ,
 *  perhaps combined with an other zone  (i.e. not found in board list):
 *          the picker is removed
 *          the zone itself if really deleted
 *          the aAuxiliaryList corresponding picker is removed (if not found : set an error)
 * After aPickList is cleaned, the aAuxiliaryList is read
 *  All pickers flagged UR_NEW are moved to aPickList
 * (the corresponding zones are zone that were created by the zone normalize and combine process,
 * mainly when adding cutout areas, or creating self intersecting contours)
 *  All pickers flagged UR_DELETED are removed, and the coresponding zones actually deleted
 * (the corresponding zones are new zone that were created by the zone normalize process,
 * when creating self intersecting contours, and after combined with an existing zone.
 * At the end of the update process the aAuxiliaryList must be void,
 *  because all pickers created by the combine process
 *  must have been removed (removed for new and deleted zones, or moved in aPickList.)
 * If not an error is set.
