range.h works with struct range data type. The resource_size_t

(1) Move cap_resource() implementation into its only user, and
(2) rename and move RESOURCE_SIZE_MAX to limits.h.

v3: Cc'ed to Andrew to pick up
(I believe with Bjorn Ack we are fine to route it via your tree as it
doesn't change any code behaviour)
