Convenience method, which frees all the memory used by a GList,
and calls free_func on every element's data.
free_func must not modify the list (eg, by removing the freed
element from it).
It can be combined with g_steal_pointer() to ensure the list head pointer
is not left dangling — this also has the nice property that the head pointer
is cleared before any of the list elements are freed, to prevent double frees
from free_func:
