Problem conclusion

Converted Group Buffer Pool statistics data to K (divided by
1024) in TEP.  Group Buffer Pool data are expressed in bytes
to kilobytes, megabytes, or gigabytes, as appropriate in
Enhanced 3270 UI.  Added logic to remove the dots at end of
DB2 message in Enhanced 3270 UI.  The following fields in
Group Buffer Pool statistics under DB2plex node in TEP are
converted to K (divided by 1024)
CROSS_INVALIDATE\READS_WITH_DATA (K)
CROSS_INVALIDATE\READS_NO_DATA (K)
