Make insert_one_record() use string_list_append(), instead of duplicating its code. Because of this, do not free the "util" member when clearing the "onelines" string lists: with the new code path it is not initialized to any value (was being initialized to NULL previously).
Also, avoid unnecessary strdup() calls when inserting names in log->list. This list always has "strdup_strings" activated, hence strdup'ing namebuf is unnecessary. This change also removes a latent memory leak in the old code.
NB: The duplicated code mentioned above predated the appearance of string_list_append().

Now with the obvious mistake in the log fixed, apologies. (s/cleanup in//)
