  Modified files:
    sys/netinet          ip_mroute.c 
  Log:
  o move mutex init/destroy logic to the module load/unload hooks;
    otherwise they are initialized twice when the code is statically
    configured in the kernel because the module load method gets
    invoked before the user application calls ip_mrouter_init
  o add a mutex to synchronize the module init/done operations; this
    sort of was done using the value of ip_mroute but X_ip_mrouter_done
    sets it to NULL very early on which can lead to a race against
    ip_mrouter_init--using the additional mutex means this is safe now
  o don't call ip_mrouter_reset from ip_mrouter_init; this now happens
    once at module load and X_ip_mrouter_done does the appropriate
    cleanup work to insure the data structures are in a consistent
    state so that a subsequent init operation inherits good state
