nfsstat: update option strings in docs

Add the missing -q option to the nfsstat(1) manpage SYNOPSIS (it is
already documented in DESCRIPTION), and add the missing -E and -q
options to the built-in usage output.

Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

nfsstat: Add an entry to output NFSPROC_APPENDWRITE count

Commit 5218d82c81f9 added a new NFSv4.1/4.2 procedure called
AppendWrite that uses a Verify to avoid a separate Getattr RPC
for the common case where the client knows the correct file
size for O_APPEND writes.

This patch modifies nfsstat so that it displays a count of
these new RPCs for the "-E -c" option.

nfsstat: Add output for counts of new RPCs to the "-E" option

Add output to the "-E" option for new RPCs related

Get rid of old nfsstat options no longer used.

The "-M" and "-N" options for nfsstat were used by the old NFS code and
have never done anything for the new NFS code.
This patch replaces code that assigns values to variables that are never
used with printf()s noting the options are ignored.
This has the side effect that it gets rid of warnings w.r.t. these
variables being assigned but never used, that occur for some builds.

Noticed during integration of the NFSv4.2 code.

Replace .h files included from old NFS directories with the new NFS ones.

Prior to this patch, nfsstat.c includes files from sys/nfs, sys/nfsclient
and sys/nfsserver. These .h files (particularily the ones in sys/nfsclient
and sys/nfsserver) are from the old NFS code and should eventually be
deprecated/removed.
This patch changes nfsstat.c to include files from the new/current NFS
code instead of the old ones in preparation for eventual removal.

Update nfsstat to list the NFSv4.2 procedures and operations.

r355677 added NFSv4.2 support to the NFS client and server. It also updated
the nfsstats structure to keep counts for the new procedures (client) and
operations (server) added for NFSv4.2.
This patch updates the "-E" option of nfsstat so that it lists counts for
these new procedures and operations.

Fix printing of Server Re-Failed and Server Faults.

nfsstat -s prints bogus large numbers for the Server Re-Failed and Server
Faults fields. This was introduced by r328588.
Although I know nothing about libxo, these lines aren't titles and this
patch seems to fix the problem, so I am committing it for rea@ who emailed
it to me.
It also deleted the trailing ':' from the title lines, since those were not
in the pre-r328588 output.

If there is a more correct fix, someone conversant with libxo will need
to do so.

Options added in rev 1.14 were not documented in usage().

Add -c, -s, and -W options to nfsstat. Improve interval output and add
wide-format option to get client-side ops and cache statistics on a single

Change client side ops to the number of attempted ops, whether cached or
not, rather then just the number of rpc's that went through to the server.
This brings nfsstat inline with systat -vm and vmstat and reduces
confusion. The combined cache percentage stats now available via
'nfsstat -cW 1' becomes very useful.

Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs. Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

Use new NFS sysctl interface to get statistics rather than reading /dev/kmem,
