MCOL-5021 Add a new member function to the DBRM class, DBRM::addToLBIDList().

Browse Source 
This function iterates over lbidList (populated by an earlier call to
DBRM::getUncommittedExtentLBIDs()) to find those LBIDs which belong to
the AUX column. It then finds the corresponding LBIDs for all other columns
which belong to the same table as the AUX LBID and appends them to lbidList.
The updated lbidList is used by invalidateUncommittedExtentLBIDs() to update
the casual partitioning information.

DBRM::addToLBIDList() only comes into play in case of a transaction ROLLBACK.
