coverity: Model g_memdup()
We model all the non-deprecated memory allocation functions from https://developer.gnome.org/glib/stable/glib-Memory-Allocation.html except for g_memdup(), g_clear_pointer(), g_steal_pointer(). We don't use the latter two. Model the former. Coverity now reports an OVERRUN vl.c:2317: alloc_strlen: Allocating insufficient memory for the terminating null of the string. Correct, but we omit the terminating null intentionally there.
