Refactor display_targets to not be recursive
This also fixes a memory leak and makes the dual-purpose "rows" variable go away in favor of storing the rows and non-verbose names separately. This also fixes some potential memory leaks and/or wrong behavior due to the config->verbosepkglists flag being flipped, which we should never be doing. Signed-off-by: Dan McGee <dan@archlinux.org>
