Subject: [PATCH 02/51] in-addr-util: be more systematic with naming our
 functions

Let's rename all our functions that process IPv4 in_addr structures
in4_addr_xyz(), following the already establishing naming logic for
this.

Leave the in_addr_xyz() prefix for functions that process the IPv4/IPv6
in_addr_union union instead.

(cherry picked from commit 5a941f5f212f38501836ccfe6164feb518b6f471)
