this should cover ports that only use memset/memcpy but still want to
pull in as much as possible from sys/lib/libsa.

Separate panic() and exit() so that the mi/default panic() can be used
without conflicting with a local exit() definition, move exit(void)
prototype to the default exit() implementation.

Use <net/if_ether.h> for ethernet specific definitions, and insert private
definitions for ARP if needed. (The new ARP macros in <net/if_arp.h> are
not used because they create larger code, and we really don't need more
than ethernet/ip support here.)
