    sys/sys              msgport.h msgport2.h 
  Implement lwkt_abortmsg() support.  This function chases down a message and
  marks it MSGF_ABORTED, requeuing it to its target port for abort reprocessing.
  The chasedown may run through multiple message forwardings and even chase the
  message all the way back to the reply port (in which case the abort becomes a
  NOP).  The queueing of a replied message is delayed if there is an abort
  chasing it down until the abort chasedown has caught up to the message.
  Support MSGF_PCATCH in the default waitport function.  If a signal is pending,
  lwkt_default_waitport() (the default assigned to mp_waitport) will request
  a message abort.  Note that we still have to wait for the message to be
  returned after requesting a message abort.
  Also do some minor performance tuning and adjust or move some of the inlines
  from msgport2.h into lwkt_msgport.c.
