    ifconfig(8): Fix IPv6 CIDR parsing error for wgaip (wg allowed-ip)
    
    The inet_net_pton() is inherited from legacy ISC named code and uses a
    legacy IPv6 CIDR format (e.g., 1:2:3:4/64), so it fails to parse some
    now valid IPv6 CIDRs (e.g., 1:2:3:4::/64).  This was causing 'wgaip'
    option to fail configure some IPv6 allowed-ips/networks.
    
    Given that inet_net_pton() is not standard and behaves differently
    across BSDs and Linux, it might be not really useful to fix/improve it
    (e.g., by porting OpenBSD's version).  Instead, I chose to write
    wg_aip_parse() to manually parse the CIDRs.
