Subject: [PATCH] Use g_list_free_full where easily possible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use g_list_free_full instead of g_list_foreach + g_list_free, so the
lists are cleared with a single call.

test-isodetect gets a void* wrapper, so there is no need to add casts
everywhere.
