[PATCH 23/45] util: Add address family set/get/reset helpers

[util] Add address family set/get/reset helpers. JB#62713

Add address family (af) helper functions to be used with a boolean array
defining which address families a provider has. Supports AF_INET and
AF_INET6 as set/get parameters. The array must be of AF_ARRAY_LENGTH
size.
