Fix RMP timing mode
- Write ABC log to the dedicated log files as they are needed for parsing the resulting delay values later
- Add print_stats cmd to the abc script
- Use the best abc result for timing instead of DELAY_4 only
- Add a test case for timing mode: worst slack reduced from 1.29 to 1.18
- Update the ok files
@maliberty The part for redirecting stdout to abc log files may seem ugly, but I don't know any other way to redirect the abc log to the required files. If you know any abc api that allows specifying the log file, it would be very helpful.

I don't see anything in abc to control where the output goes. Originally we forked abc which avoided this issue. When abc was integrated I believe the thinking was that we would fork OR and in that process we could call abc + gpl to better evaluate the results. However right now it doesn't fork anything which makes the whole process serial. If you fix this problem the output will become secondary as it will be in the log file of the forked run. Better than forking would be to use dst so we aren't limited to one machine.
