o Obsolete the undocumented ``set weight'' command.

o If we're using RADIUS and the RADIUS mtu is less than our
  peers mru/mrru, reduce our mtu to this value for NetBSD too.
o Make struct throughput's sample period dynamic and tweak the ppp
  version number to reflect the extra stuff being passed through
  the local domain socket as a result (MP mode).
o Measure the current throughput based on the number of samples actually
  taken rather than on the full sample period.
o Keep the throughput statisics persistent while being passed to
  another ppp invocation through the local domain socket.
o When showing throughput statistics after the timer has stopped, use
  the stopped time for overall calculations, not the current time.
  Also show the stopped time and how long the current throughput has
  been sampled for.
o Use time() consistently in throughput.c
o Tighten up the ``show bundle'' output.
o Introduce the ``set bandwidth'' command.
o Rewrite the ``set autoload'' command.  It now takes three arguments
  and works based on a rolling bundle throughput average compared against
  the theoretical bundle bandwidth over a given period (read: it's now
  functional).
