Change IPV4 specific macros LOOPBACK MULTICAST LOCAL_MCAST BADCLASS
and ZERONET macros to inline functions ipv4_is_<type>(__be32 addr)
Adds type safety and arguably some readability.
Changes since last submission:
Removed ipv4_addr_octets function
Used hex constants
Converted recently added rfc3330 macros
