  Modified files:
    sys/sys              kernel.h eventhandler.h 
    sys/kern             subr_eventhandler.c 
  Log:
  - Convert the per-eventhandler list mutex to a lockmgr lock so that it can
    be safely held across an eventhandler function call.
  - Fix an instance of the head of an eventhandler list being read without
    the lock being held.
  - Break down and use a SYSINIT at the new SI_SUB_EVENTHANDLER to initialize
    the eventhandler global mutex and the eventhandler list of lists rather
    than using a non-MP safe initialization during the first call to
    eventhandler_register().
  - Add in a KASSERT() to eventhandler_register() to ensure that we don't try
    to register an eventhandler before things have been initialized.
