  Log:
  * Greatly reduce the complexity of the LWKT messaging and port abstraction.
    Significantly reduce the overhead of the subsystem.
  
  * The message abort algorithm has been rewritten.  It now sends a
    separate message to issue the abort instead of trying to requeue
    the original message.  This also means the TAILQ embedded in the
    lwkt_msg structure can be used by unrelated code during processing
    of the message.
  
  * Numerous MSGF_ flags have been removed, and all the LWKT msg/port
    algorithms have been rewritten and simplified.  The message structure
    is now only touched by the current owner in all situations.
  
  * Numerous structural fields have been removed.  In particular, the
    fields used for message abort sequencing have been simplified and
    we do not try to embed a 'command' field in the base LWKT message
    any more.
  
  * Clean up the netmsg abstraction, which is used all over the network stack.
    Instead of trying to overload fields in lwkt_msg we now simply extend
    the base lwkt_msg into struct netmsg.  The function dispatch now takes
    a netmsg and returns void (before we had to return EASYNC), and we no
    longer need weird casts.
  
    Accept/connect message aborts are now greatly simplified.
