First step towards making uiomove() take a size_t size argument:
- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.
- rewrite uiomovei() as an uiomove() wrapper.

introduce a flag member to struct nfs_aiod, and use flags instead of the exit
and worked members. nad_worked becomes NFSAIOD_WAKEUP, which is set after if
an aiod was removed from the idle list and woken up by nfs_asyncio().

don't rely on tsleep wchans being unique, that is keep going back to sleep if
woken up unless the NFSAIOD_WAKEUP flag is set.

fix a divide by zero crash if nfs.vfs.iothreads is set to 0, as that can happen
when we recalculate the maximum buf's to queue up for each aiod.

in nfs_asyncio() set the nad_mnt to NULL before returning the aiod back to the
idle list in the case where we have already queued up to many bufs, otherwise
we trip an assertion.

minimize the time we are holding the nfs_aiodl_mtx to only when we are inserting
or removing from the lists, with the exception of nfs_set_naiod() as it would
make the loops more complicated and its uncommon in any case.

Rework the way we do async I/O in nfs. Introduce separate buf queues for
each mount, and when work is "found", peg an aiod to that mount todo the
I/O. Make nfs_asyncio() a bit smarter when deciding when to do asyncio
and when to force it sync, this is done by keeping the aiod's one two lists,
an "idle" and an "all" list, so asyncio is only done when there are aiods
hanging around todo it for us or are already pegged to the mount.

Idea liked by at least beck@ (and I think art@).
Extensive testing done by myself and jasper and a few others on various
arch's.

Using the buf pointer returned from incore is a really bad idea.
Even if we know that someone safely holds B_BUSY and will not modify
the buf (as was the case in here), we still need to be sure that
the B_BUSY will not be released while we fiddle with the buf.

In this case, it was not safe, since copyout can sleep and whoever was
writing out the buf could finish the write and release the buf which
could then get recycled or unmapped while we slept. Always acquire
B_BUSY ourselves, even when it might give a minor performance penalty.

We don't count buffercache stats in the B_PHYS case, so fix nfs to not
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 };-)"

Correct cases of mishandling of pending reads and writes to prevent
them going negative - this consists of identifying a number of cases of
IO not going through the buffer cache and marking those buffers with
B_RAW - as well as fixing nfs_bio to show pending writes and reads through
the buffer cache via NFS

still has a problem with mishandling the counters I believe in the
async/sync fallback case where counters stay positive which will be
addressed seperately.

Ensure each nfsiod can actually enqueue more than one asynchio - this mirrors
the accidental situation that used to happen when it leaked buffers and allowed
the syncer to do it, however this puts a limit on how much of the buffer cache
it is allowed to consume to a sensible amount - improves nfs write performance
since we don't have to do tons of them synch now.

Modifies the existing code to use wakeup_one instead of cruft, and now
all nfsiod's tsleep the same way.

Kernel stack can be swapped. This means that stuff that's on the stack
should never be referenced outside the context of the process to which
this stack belongs unless we do the PHOLD/PRELE dance. Loads of code

Protect calls to biodone with splbio. Some functions called

UBC was a disaster. It worked very good when it worked, but on some
machines or some configurations or in some phase of the moon (we actually
don't know when or why) files disappeared. Since we've not been able to
track down the problem in two weeks intense debugging and we need -current
to be stable, back out everything to a state it had before UBC.

We apologise for the inconvenience.

Merge in the unified buffer cache code as found in NetBSD 2001/03/10. The

state, but will require optimizations and additional cleanups.

Merge in -current from two days ago in the SMP branch.
As usual with merges, they do not indicate progress, so do not hold
your breath for working SMP, and do not mail me and ask about the
state of it.  It has not changed.  There is work ongoing, but very, very
slowly.  The commit is done in parts as to not lock up the tree in too
big chunks at a time.
