  Modified files:
    sys/conf             param.c 
    sys/kern             kern_lock.c 
    sys/sys              kernel.h lock.h 
    sys/vm               vm_map.h 
  Log:
  For lockmgr mutex protection, use an array of mutexes that are allocated
  and initialized during boot.  This avoids bloating sizeof(struct lock).
  As a side effect, it is no longer necessary to enforce the assumtion that
  lockinit()/lockdestroy() calls are paired, so the LK_VALID flag has been
  removed.
  
  Idea taken from:	BSD/OS.
