tracing/filter: Add startup tests for events filter
Adding automated tests running as late_initcall. Tests are compiled in with CONFIG_FTRACE_STARTUP_TEST option. Adding test event "ftrace_test_filter" used to simulate filter processing during event occurance. String filters are compiled and tested against several test events with different values. Also testing that evaluation of explicit predicates is ommited due to the lazy filter evaluation.
