operations (non-idempotent ones) under the assumption that the reply from
the server is for a duplicate of the original request.
However, most (all) NFS server today have a duplicate reply cache that
address this problem and these kludges have been shown to cause problems
with some applications (most notably dovecot as pointed out by brad@).
For more information:

And revision 1.277 of sys/nfsclient/nfs_vnops.c in FreeBSD.

nfsm_uiotombuf():
- no meaningful return, function becomes void
- replace frankensteined uiomove/MGET with actual call to uiomove
nfsm_strtmbuf():
- no meaningful return, becomes void
- rename and reorder parameters to be consistent with other functions
- becomes wrapper to nfsm_uiotombuf
nfsm_buftombuf():
- new function; unused but slated for future use
- wrapper to nfsm_uiotombuf
As a bonus, making these functions void removes much unneeded code and
garbage collects `magic' variable t2 which was only used (invisibly)
by the macros from nfsm_subs.h
Preps the way for removing much more NFS goo...

More NFS-related kernel shrinkage...
When you use a macro ~200 times, it tends to bloat your code, so make a
function out of it.
Shaves ~8.5 kB from my kernel.

Use the va_blocksize, that is the blocksize of the underlying exported
file system instead of the DIRBLKSIZ constant to size the chunks.

Cleanup and partly redo the way we create the RPC header, by having
nfsm_rpchead() do a bit more work. Right now this is pretty RPCAUTH_UNIX
centric, but since it is the only auth method we support right now thats
fine.
Make sure we can never generate a zero xid, thats forbidden by the RFC.
Misc cleanup.

- Remove setting of the NFSMNT_DISMINPROG flag, its set
and unset in the same function servering no purpose,
im however going to reuse it shortly.
- kill an if thats always true (NFSMNT_KERB cant be set)
- misc cleanup and KNF.

"ap = v" comments in under 8 seconds, so it must be ok. and it compiles

Basically the usage of daddr_t was to math out arguments to
nfs_getcacheblk, wich calls getblk();

nfsv2 client case, this matches v3 behaviour to that extent.
This is to work around the fact that when the namecache is large, we
dont purge vnodes correctly out of it.
