- Add MTX_SYSINIT and SX_SYSINIT as macro glue for allowing sx and mtx

  locks to be able to setup a SYSINIT call.  This helps in places where
  a lock is needed to protect some data, but the data is not truly
  associated with a subsystem that can properly initialize it's lock.
  The macros use the mtx_sysinit() and sx_sysinit() functions,
  respectively, as the handler argument to SYSINIT().
