Hyper-V hot channel effect:
Operation latency on hot channel is only _half_ of the operation
latency on cold channels.
This commit takes the advantage of the above Hyper-V host channel
effect, and can reduce more than 75% latency and more than 50%
latency stdev, i.e. lower and more stable/predictable latency,
for various types of web server workloads.

This patch sets the default uid/gid values for "nobody" and "nogroup"
to the values in the password and group databases. Normally nfsuserd(8)
will override these with whatever is in the password/group databases,
so these values are only used when the databases entries aren't available.
It would be nice to use the definitions in sys/conf.h, but those are
in the _KERNEL section of the file.

An NFSv4 server has the option of allowing a Read to be done using a Write
Open. If this is not allowed, the server will return NFSERR_OPENMODE.
This patch attempts the read with a write open and then disables this
if the server replies NFSERR_OPENMODE.
This change will avoid some uses of the special stateids. This will be
useful for pNFS/DS Reads, since they cannot use special stateids.
It will also be useful for any NFSv4 server that does not support reading
via the special stateids. It has been tested against both types of NFSv4 server.

The NFSv4.1/pNFS client does not use/need a backchannel for the Data Server (DS)
sessions, so the flag should only be set for MetaData Server (MDS) sessions.
This patch should have been a part of r317275.

colors.
Colors are still hard-coded as 15 (normally lightwhite) for the interior
and 0 (normally black) for the border, but these are now values used in
2 expressions instead of built in to the algorithm. The algorithm used
a fancy and/or method, but this gives no control over the colors except
and'ing all color planes off gives black and or'ing all color planes on
gives lightwhite. Just draw the border and interior in separate colors
using the same method as for characters, including its complications to
optimize for VGA adaptors. Optimization is not really needed here, but
for the VGA case it avoids being slower than the and/or method. The
optimization is worth about 30%.
If the commands had failed previously, it would press on and result in a
series of cascading failures. Fail early and continue on to the next case
instead of executing additional commands after a previously failed series
of steps.

- Add `use strict`.
- Use `use warnings` instead of using `-w` in the shebang.
- Don't unlink $cmd when done (prevents unnecessary rebuilding).
- Improve the error message when running with insufficient permissions, e.g.,
non-root.

The "return layout on close" case in the pNFS client was badly broken.
Fortunately, extant pNFS servers that I have tested against do not
do this. This patch fixes it. It also changes the way the layout stateid.seqid
is set for LayoutReturn. I think this change is correct w.r.t. the RFC,
but I am not 100% sure.
This was found during recent testing of the pNFS server under development.

The test suite currently lacks basic sanity checks to ensure that egrep,
fgrep, and grep are actually matching the right expression types, i.e. passing
the right flags to regcomp(3). Amend the test suite to make sure that not only
are the individual versions doing the right thing, but also that we don't have some
kind of frankenregex situation happening where egrep is accepting a BRE or
grep an ERE.
I've chosen to not expand the 'basic' test but to add the 'grep_sanity' checks
to their own test case since this is testing for more than just 'grep matches things',
but actual expression types.

The NFSv4.1/pNFS client wasn't doing a newnfs_disconnect() call for the
connection to the Data Server (DS) under some circumstances. The main
effect of this was a leak of malloc'd structures in the krpc. This patch
adds the newnfs_disconnect() calls to fix this.

gctl_dump(3) is only exposed when stdio.h is #include'd first, per its
addition in r112510. The reasoning noted for the conditional "exposure"
of the function was to "limit #include pollution".
This addresses an issue I found with the documentation when looking at
bug 218809, which in turn addresses a -Wimplicit-function-declaration
compiler warning in `tools/regression/geom_gpt/test.c` (it uses
gctl_dump(3)).

Instead of casting listmax and numdirs to unsigned values just define
them as unsigned and avoid the casts. Use reallocarray(3).
While here, fs_ncg is already unsigned so the cast is unnecessary.

For now there isn't any per-VAP WME state. The eventual aim is to migrate
the driver direct use of WME parameters over to use these methods as
appropriate (global for most devices, per-VAP for firmware NICs that support
it) in preparation for actual per-VAP WME (and other thing) state change
support.
In my eagerness to eliminate a branch which is taken once per 2^38
bytes of keystream, I forgot that the state words are in host order.
Thus, the counter increment code worked fine on little-endian
machines, but not on big-endian ones. Switch to a simpler (branchful)
solution.
