    sys/netinet          tcp.h tcp_input.c tcp_output.c 
                         tcp_syncache.c tcp_var.h 
  Log:
  Consolidate insertion of TCP options into a segment from within tcp_output()
  and syncache_respond() into its own generic function tcp_addoptions().
  
  tcp_addoptions() is alignment agnostic and does optimal packing in all cases.
  
  In struct tcpopt rename to_requested_s_scale to just to_wscale.
  
  Add a comment with quote from RFC1323: "The Window field in a SYN (i.e.,
  a <SYN> or <SYN,ACK>) segment itself is never scaled."
