Philippe Mathieu-Daudé 522a9b94e0 util/iov: Avoid dynamic stack allocation
Use autofree heap allocation instead of variable-length array on the
stack.

The codebase has very few VLAs, and if we can get rid of them all we
can make the compiler error on new additions.  This is a defensive
measure against security bugs where an on-stack dynamic allocation
isn't correctly size-checked (e.g.  CVE-2021-3527).
