	ret_set_ksft_status() calls ksft_status_merge() with the current return status and the last one. It treats a non-zero return code from ksft_status_merge() as an indication that the return status was overwritten by the last one and therefore overwrites the return message with the last one. Currently, ksft_status_merge() returns a non-zero return code even if the current return status and the last one are equal. This results in return messages being overwritten which is counter-productive since we are more interested in the first failure message and not the last one. Fix by changing ksft_status_merge() to only return a non-zero return code if the current return status was actually changed. Add a test case which checks that the first error message is not overwritten.

2024-03-28	selftests: forwarding: Add a test for testing lib.sh functionality	Petr Machata
	Rerunning various scenarios to make sure lib.sh changes do not impact the observable behavior is no fun. Add a selftest at least for the bare basics -- the mechanics of setting RET, retmsg, and EXIT_STATUS. Since the selftest itself uses lib.sh, it would be possible to break lib.sh in such a way that invalidates result of the selftest. Since the metatest only uses the bare basics (just pass/fail), hopefully such fundamental breakages would be noticed.
