Integrating an enhancement from Michael Shield's guest
branch. Track2SQL now records the end time of each process
(when it is reported). This information is reported for every
completed process when -vserver=2|3 logging is enabled.
If verbose server logging is enabled this is more reliable than
start 'time' + 'lapse' because (by default) lapse is only reported
when it exceeds a certain threshold. If, however, vtrack=1 is
set then lapse time will be reported for every command.
Note: this change brings a schema change. It adds a
'endTime' column to the process table.
