Add pnfsserver.4 to the Makefile for nfsd.

Add a new man page that briefly describes the pNFS variant of the NFSv4.1
protocol.

This is a content change.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Modify nfsd.c to add support for the experimental nfs server.
This includes the addition of a new flag "-4" that will force
use of the experimental server with nfsv4 support in it. This
commit also adds two new man pages to the repository that are
NFSv4 specific. One describes the file used by the server to
restart nfsv4 services safely. The other is a brief overview
of nfsv4 and its setup.

- Import the HEAD csup code which is the basis for the cvsmode work.

ANSI'fy nfsd(8) and some minor changes to make it WARNS=6 clean.

This commit does not affect the code generated, as proven by md5'ing
resulting binaries.

Bump WARNS accordingly.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Userland part of nfs client/server split and cleanup.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for sbin/ to 8.

Don't use libutil now that setproctitle() is in libc

Use libcrypto instead of libdes.

Removed definition of _NEW_VFSCONF. The new vfsconf interface is now
the default.

Merge from Lite2 (use new getvfsbyname() interface)

oops, do it right this time

Link with libutil for kerberos too

Make nfsd use setproctitle from libutil...

Old code is still #ifdef OLD_SETPROCTITLE for comparison with the old
code.

Add support for kerberised NQNFS.

Delete obsolete references to librpc.a.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.
