MFC: m_tag support

Replace aux mbufs with packet tags:

  o instead of a list of mbufs use a list of m_tag structures a la openbsd
  o for netgraph et. al. extend the stock openbsd m_tag to include a 32-bit
    ABI/module number cookie
  o for openbsd compatibility define a well-known cookie MTAG_ABI_COMPAT and
    use this in defining openbsd-compatible m_tag_find and m_tag_get routines
  o rewrite KAME use of aux mbufs in terms of packet tags
  o eliminate the most heavily used aux mbufs by adding an additional struct
    inpcb parameter to ip_output and ip6_output to allow the IPsec code to
    locate the security policy to apply to outbound packets
  o bump __FreeBSD_version so code can be conditionalized
  o fixup ipfilter's call to ip_output based on __FreeBSD_version
