/*
 * akerr_init() registers a human-readable name for each library error code.
 * Verify the names are actually installed (mutation testing showed the
 * registration calls could be deleted without any test noticing).
 *
 * Note: AKERR_EOF, AKERR_ITERATOR_BREAK and AKERR_NOT_IMPLEMENTED are omitted --
 * they are valid codes but akerr_init does not register a display name for them,
 * so akerr_name_for_status returns an empty string rather than a known name.
