Arnaldo Carvalho de Melo 81f17c90f1 perf test: Add 'struct test *' to the test functions
This way we'll be able to pass more test specific parameters without
having to change this function signature.

Will be used by the upcoming 'shell tests', shell scripts that will
call perf tools and check if they work as expected, comparing its
effects on the system (think 'perf probe foo') the output produced, etc.
