This patchset is based on Arnaldo's perf/core.
Previous version can be found from [1].
Patch 1/7 - 4/7 are error message related patches.
Patch 5/7 - 7/7 are testing related patches.
v1 -> v2:
- Use enum for error code.
- Eliminate for-loop, directly get error message from array using array index.
- Classify error reason of program loading failure.
- Improve message when version mismatching.
