  Log:
  Fix some long standing bugs in writing to the BPF device attached to
  a DLT_NULL interface. In particular:
  
          1) Consistently use type u_int32_t for the header of a
             DLT_NULL device - it continues to represent the address
             family as always.
          2) In the DLT_NULL case get bpf_movein to store the u_int32_t
             in a sockaddr rather than in the mbuf, to be consistent
             with all the DLT types.
          3) Consequently fix a bug in bpf_movein/bpfwrite which
             only permitted packets up to 4 bytes less than the MTU
             to be written.
          4) Fix all DLT_NULL devices to have the code required to
             allow writing to their bpf devices.
          5) Move the code to allow writing to if_lo from if_simloop
             to looutput, because it only applies to DLT_NULL devices
             but was being applied to other devices that use if_simloop
             possibly incorrectly.
