[svn-r13801] Output improvement.
Added a header message showing the purpose and explanation that the test is for inoformation and always exits 0. Also added a summary at the end. Some other cosmetic changes (moved couple function code up, added some more printf, fflush statements.) Tested platform: kagiso.
