Found with dlg@'s amazing mbuf debug diff, fix is based on
the same thing in NetBSD (by yamt@netbsd.org).

FreeBSD commit message:
Refactor the NFS over UDP retransmit timeout estimation logic to allow
the estimator to be more easily tuned and maintained.
There should be no functional change except there is now a lower limit
on the retransmit timeout to prevent the client from retransmitting
faster than the server's disks can fill requests, and an upper limit
to prevent the estimator from taking to long to retransmit during a
server outage.

just store the maximun amount of rexmits in one place and
cleanup. Also make sure this only effects soft mounts.

increment the num{read,write} and pending{read,write} statistics in that
case, since biodone won't change them on completion.
On another note, I'm not sure that we use physical buffers for swapping
over nfs anymore, so this chunk may be superfluous.
beck@ came up with the same diff "So anyway rather than me commiting it
from my copy, I'm giving you the OK and the commit. since it officially
makes you a buffer cache and NFS hacker };-)"

levels. This will allow for platforms where soft interrupt levels do not
map to real hardware interrupt levels to have soft ipl values overlapping
hard ipl values without breaking spl asserts.

timeouts. Rrids us of the ugly cur_sec variable, and some shadows.
Also helps with granularity.
Diff from blambert@ who asked me to commit this since he's away for
some days and we wanted to put this in with the timespec changes in
the nfsnode.

mtime, gives us better granularity, helps with cache consistency.

VA_EXCLUSIVE. Handle this in NFS, also in NFS use arc4random()
for the create verifier instead of an uninitialized long and
the address of the first interface (which is likely to be lo0).

the udp receive space got completely filled up. Even if the next
packet from the server was a small reply, it got dropped by
udp_input(). After a second the client resent the NFS request.
Doubling rcvreserve reduces the chance of retransmits by having
enough recv space for multiple NFS replies even if there comes a
big one.

of 5 cases. In the functions nfs_reconnect() and nfs_reply() put
the TAILQ_FOREACH over nfs_reqq also inside splsoftnet() protection.

requires well-formed mbuf chains to work. Existing function name is now
a wrapper to this interface. Much, much more work to follow which will
build on this.
Truly change we can believe in.

as for open/read/write etc, that is assume that the file
as already been opened proper, this fixes an ancient
ftruncate bug, that is if ftruncate was called on a file
with no write modes, we'd return EACCES, this breaks posixy
behavior. however, for e.g. truncate() we'll return EACCESS
as we should.

I had forgotten about this PR, and the fix but niklas@ ran
into similar issues which prompted another review of this.
