Add MM Auth test; add auth_action_str() function

Add basic MM Authentication test setup, with fake DB access and RAND_bytes().

So far implement simple tests for IO error during DB access and missing auth
entry.

To print the auth action during tests, add struct auth_action_names and
auth_action_str() inline function in auth.[hc].
