http://jira.cubrid.org/browse/LETS-194

Create the transaction table checkpoint mechanism to be executed by a daemon on the TSRS (Transaction Server - Remote Storage).

Implementation:
- new checkpoint function for log_checkpoint_trantable that only collects the transaction table information and adds it to the existing metalog; also removes and saves previous transaction table checkpoint(s)
- new "log_checkpoint_trantable" daemon that loops every minute and executes the log_checkpoint_trantable function
