  Modified files:
    sys/sys              socketvar.h 
    sys/kern             uipc_socket.c 
  Log:
  Introduce a mutex into struct sockbuf, sb_mtx, which will be used to
  protect fields in the socket buffer.  Add accessor macros to use the
  mutex (SOCKBUF_*()).  Initialize the mutex in soalloc(), and destroy
  it in sodealloc().  Add addition, add SOCK_*() access macros which
  will protect most remaining fields in the socket; for the time being,
  use the receive socket buffer mutex to implement socket level locking
  to reduce memory overhead.
