thorpej 0585ce1489 Make insertion of data into socket buffers O(C): 
* Keep pointers to the first and last mbufs of the last record in the
  socket buffer.
* Use the sb_lastrecord pointer in the sbappend*() family of functions
  to avoid traversing the packet chain to find the last record.
* Add a new sbappend_stream() function for stream protocols which
  guarantee that there will never be more than one record in the
  socket buffer.  This function uses the sb_mbtail pointer to perform
  the data insertion.  Make TCP use sbappend_stream().

On a profiling run, this makes sbappend of a TCP transmission using
a 1M socket buffer go from 50% of the time to .02% of the time.

Thanks to Bill Sommerfeld and YAMAMOTO Takashi for their debugging
assistance!
