Various more tweaks from John Dyson to improve read ahead calculations.
vfs_subr.c:
Only wakeup if numoutput is 0 in vwakeup().

metadata aren't thrashed by regular file I/O.
Added mechanism to limit the amount of outstanding I/O on a given vnode.
Pagedaemon wakeup policy changed to skew priority a little in favor of
file caching.
Slight code reorganization to improve clarity.
Added a few more comments.

IP addresses and/or protocol+port, but in the case where both are
supplied, it happily accepts the command but ignores the proto+port
It also attempts to handle the case where the second IP address
is omitted, but this doesn't work.

commands per target. I could have followed the route of the ncr driver
and gone to great lengths to get the SCSI subsystem to support more, but
I think I'll use the time saved to help Julian and Peter make tagged
queuing a better handled generic feature. This also includes some comment
and enum clean up and a possible fix for the hanging PCI controllers.
the same as when initializing the in-core copies. Adjust checksums in
labels after adjusting labels. This finishes fudging the on-disk label to
make it coherent with the in-core label.
Handle EIO during initialization better.
Initialize the compatibility slice to the whole disk If there are no real
slices.
Don't warn about adjusting offsets in the label to make the 'c' partition
start at 0. The 'c' offset is now always absolute on-disk and 0 in-core
so an adjustment is usually required.
Don't confuse LABEL_PART with RAW_PART so much.
Check for partitions being within slices differently.
pager(). Almost completely rewrote vm_mmap(); when John gets done with
the bottom half, it will be a complete rewrite. Deprecated most use of
vm_object_setpager(). Removed side effect of setting object persist
in vm_object_enter and moved this into the pager(s). A few other
cosmetic changes.
returned to user mode without enabling ASTs. The problem fixed itself
at the next syscall or non-FPU trap, if any. It hung the system for
a test process that masked SIGFPE's and divided by zero. The faulting
division was returned to endlessly and this gave plently of opportunities
for the swi_ast_phantom case to be reached; after it was reached the
system hung because the ASTs for preemption and SIGINT handling were
disabled.
via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)
Now it is at least possible to prohibit one user opening maxfiles

the same as the changes made in the repository. This is often seen by
people with remote CVS trees that have applied their local patches to the
master site. a 'cvs update' will show bogus conflicts.

In diffutils 2.6 and 2.7, diff3 -A complains about identical overlapping
changes. They're different from the ancestor but not from each other...
Why bother? The patch below fixes this nonsense and preserves [B]ackwards
compatiblity with the -B flag (also --show-bogus-conflicts).
Party on...

Since functions will come and go from libcompat as they are deprecated
it makes no sense to build a shared library out of it as it will change.
Based on freedback from Terry and Jonas on the mailing lists.
