Modified Files:
	syssrc/sys/netinet: tcp_output.c tcp_subr.c

Log Message:
* Instrument tcp_build_datapkt().
* Remove the code that allocates a cluster if the packet would
  fit in one; it totally defeats doing references to M_EXT mbufs
  in the socket buffer.  This drastically reduces the number of
  data copies in the tcp_output() path for applications which use
  large writes.  Kudos to Matt Thomas for pointing me in the right
