tests: improve diagnostics output & make "release builds" work

This commit adds a few macros and helper functions for the unit test
programs. Those are used instead of asserts to provide more fine
grained diagnostics on the one hand and on the other hand because
they also work if NDEBUG is defined, unlike asserts that get eliminated
in that case.
