Rename IP and Ethernet equality checkers from _cmp to _eq

Functions ending in cmp are expected to return 0 on equality but these
return non-zero.

eth_addr_cmp -> eth_addr_eq

ip_addr_cmp -> ip_addr_eq
ip4_addr_cmp -> ip4_addr_eq
ip6_addr_cmp -> ip6_addr_eq

ip_addr_netcmp -> ip_addr_net_eq
ip4_addr_netcmp -> ip4_addr_net_eq
ip6_addr_netcmp -> ip6_addr_net_eq

ip_addr_cmp_zoneless -> ip_addr_zoneless_eq
ip6_addr_cmp_zoneless -> ip6_addr_zoneless_eq

ip6_addr_cmp_zone -> ip6_addr_zone_eq
ip6_addr_netcmp_zoneless -> ip6_addr_net_zoneless_eq
ip6_addr_nethostcmp -> ip6_addr_nethost_eq
ip6_addr_cmp_packed -> ip6_addr_packed_eq
ip6_addr_cmp_solicitednode -> ip6_addr_solicitednode_eq

All call sites have been changed, and fallback macros have been added to not
break external users.

   * [Enter new changes just after this line - do not remove this line]
+  * The eth_addr_cmp and ip_addr_cmp set of functions have been renamed to eth_addr_eq, ip_addr_eq
+    and so on, since they return non-zero on equality. Macros for the old names exist.
