Title: Disk aggregate and index aggregate could corrupt memory

If the result of a disk aggregate or index aggregate was a variable
size row, roxie heap could get overwritten

Renamed the cloneRow function - which is never safe to use in new
memory paradigms - to ensure that no other issues remain. A couple
of changes in hthor to avoid the unsafe functions were unlikely to
cause corruptions in practice.

Legacy thor may need changes to rename calls to these deprecated
functions.
