Diffs for NetBSD-current 3.99.11

[Ty Sarna]

In conjuntion with the previous patch, the following patch makes 0.41
compile and (seem to) work with NetBSD-current up 3.99.11 (through
2005-11-26).

.11 represents the merge of the yamt-vop branch.  VOP_TRUNCATE and
VOP_UPDATE were removed.  nnpfs used those internally.  The patch is
based on my understanding of this as follows:

 - if your filesystem called a obsolete VOP_XXX internally before, you
   should simply replace this with a direct call to your foofs_xxx()
   implementation directly.

 - nnpfs does not provide nnpfs_truncate or nnpfs_update impelementations.

 - thus the calls to VOP_TRUNCATE/UPDATE were calling the default function

 - the default function is nnpfs_eopnotsupp, which just returns EOPNOTSUPP

 - Thus the call to (void) VOP_TRUNCATE(...) is a no-op and can be
   elided (I left it active for previous version of netbsd anyway)

 - the call to error = VOP_UPDATE(...) is equivalent to
   error = EOPNOTSUPP, which would disable the following code
   that updates size/time/etc of nodes and dirties it, which seems
   wrong. So, I have removed the call instead (for >= 3.99.11).

With this patch, from my limited (2 minutes) of testing, arla seems to
work on 3.99.11, but I am not confident it is TRT...

yamt & lha, I would appreciate if you would look this over and make sure
it seems correct to you...

Thanks.
