  Log:
  Introduce sbreserve_locked(), which asserts the socket buffer lock on
  the socket buffer having its limits adjusted.  sbreserve() now acquires
  the lock before calling sbreserve_locked().  In soreserve(), acquire
  socket buffer locks across read-modify-writes of socket buffer fields,
  and calls into sbreserve/sbrelease; make sure to acquire in keeping
  with the socket buffer lock order.  In tcp_mss(), acquire the socket
  buffer lock in the calling context so that we have atomic read-modify
  -write on buffer sizes.
