lib: refactory cisco access list net wildcard
Wildcards bits have the opposite representation of a network mask,
example:
192.168.0.0/24 has the following netmask 255.255.0.0 and the wildcard
representation is 0.0.255.255.
To avoid future confusion lets put those definitions into a macro so we
know for sure which form to use.
