  Log:
  Merge additional socket buffer locking from rwatson_netperf:
  
  - Lock down low hanging fruit use of sb_flags with socket buffer
    lock.
  
  - Lock down low hanging fruit use of so_state with socket lock.
  
  - Lock down low hanging fruit use of so_options.
  
  - Lock down low-hanging fruit use of sb_lowwat and sb_hiwat with
    socket buffer lock.
  
  - Annotate situations in which we unlock the socket lock and then
    grab the receive socket buffer lock, which are currently actually
    the same lock.  Depending on how we want to play our cards, we
    may want to coallesce these lock uses to reduce overhead.
  
  - Convert a if()->panic() into a KASSERT relating to so_state in
    soaccept().
  
  - Remove a number of splnet()/splx() references.
  
  More complex merging of socket and socket buffer locking to
  follow.
