- introduce variable _BB_CONFIG_DEP to the new test harness.
This is used to see if given tests should be run (are available) or not. Print "UNTESTED: descr" if the applet or feature is not available. - add _BB_CONFIG_DEP to existing new.tests - move old grep test to new test infrastructure and add a few more test for grep.
