It's not that disruptive even for backporting because %z modifier has been available for a long time so should backport fine.  This was mostly done with a sed script plus some hand fixups.

Sorry for a "dumb" question but `%z` is for size_t arguments, so why are we using it to replace INTX/UINTX_FORMAT ??? I get that size_t and intx happen to be the same size but still ... if I see  `%z` I expect to see a size_t argument passed in.
