Robert Watson b9b0dac33b Move towards more explicit support for various network protocol stacks
in the TrustedBSD MAC Framework:

- Add mac_atalk.c and add explicit entry point mac_netatalk_aarp_send()
  for AARP packet labeling, rather than using a generic link layer
  entry point.

- Add mac_inet6.c and add explicit entry point mac_netinet6_nd6_send()
  for ND6 packet labeling, rather than using a generic link layer entry
  point.

- Add expliict entry point mac_netinet_arp_send() for ARP packet
  labeling, and mac_netinet_igmp_send() for IGMP packet labeling,
  rather than using a generic link layer entry point.

- Remove previous genering link layer entry point,
  mac_mbuf_create_linklayer() as it is no longer used.

- Add implementations of new entry points to various policies, largely
  by replicating the existing link layer entry point for them; remove
  old link layer entry point implementation.

- Make MAC_IFNET_LOCK(), MAC_IFNET_UNLOCK(), and mac_ifnet_mtx global
  to the MAC Framework rather than static to mac_net.c as it is now
  needed outside of mac_net.c.
