  Log:
  Introduce some functions in the vnode locks namespace and in the ffs
  namespace in order to handle lockmgr fields in a controlled way instead
  than spreading all around bogus stubs:
  - VN_LOCK_AREC() allows lock recursion for a specified vnode
  - VN_LOCK_ASHARE() allows lock sharing for a specified vnode
  
  In FFS land:
  - BUF_AREC() allows lock recursion for a specified buffer lock
  - BUF_NOREC() disallows recursion for a specified buffer lock
  
  Side note: union_subr.c::unionfs_node_update() is the only other function
  directly handling lockmgr fields. As this is not simple to fix, it has
  been left behind as "sole" exception.
