MFC: r320323
Add RPC count reporting for the two new RPCs added by r320322.

MFC: r309197
Add a -E flag to nfsstat.c so that it prints out the NFSv4.1
procedure/operation counts.
It also avoids clipping the counts at 9 digits.

MFC: r304058, r304066, r304194
Update nfsstat.c to use the new kernel nfsstat structure and
add the new "-d" flag from D1626.
The man page will be updated in a subsequent commit.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Use the DELTA() macro to tidy the server-side interval stats code a bit.

Partially revert r52493 and change client side interval statistics to
report the actual number of RPCs issued, not the theoretical number
that would be issued if all caching was disabled.

Modify nfsstat.c so that it prints out an error when a non-root

Add a "-m" option to nfsstat, which dumps out the
actual options used by all NFS mounts. Works for
the new/default NFS client only.

Fix a bug which prevents "nfsstat -W" for server statistics from working.

Fix nfsstat(1) so that it prints out correct stats for the
new NFS server when the "-e" option is not used. The bug was
that srvrpccnt[] was being indexed by NFSPROC_XXX when it needs
to be indexed by NFSV4OP_XXX.

Change the sysctl naming for the old and new NFS clients
to vfs.oldnfs.xxx and vfs.nfs.xxx respectively. This makes
the default nfs client use vfs.nfs.xxx after r221124.

- Add a forgotten -o to usage().
- Sync usage() with manpage's SYNOPSIS.

Modify nfsstat(1) so that it reports statistics for the
new NFS client/server by default, in a format compatible
with the old NFS client/server. Also add a "-o" flag that
forces nfsstat(1) to get statistics for the old NFS
client/server.

Modify nfsstat(1) so that it prints out the buffer cache

getopt and friends are declared in <unistd.h>
getopt returns -1 not EOF.

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
line.

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.

Merged from Lite2. This was mostly already done, mostly indirectly
via wollman's changes in rev.1.2 being adopted by Lite2 and the
nfsv3 changes in rev.1.3 being adopted by both FreeBSD and Lite2.
We were only missing lookup of the type number for nfs (MOUNT_NFS
doesn't exist in Lite2).

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)

Boy, I'm glad we're not using sup anymore. This update would have been

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.
