arp: convert arp(8) to netlink.

The change is intended to be fully transparent to the users.
Similarly to route(8) and netstat(8), arp can be build without
netlink by defining WITHOUT_NETLINK in make.conf.

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.

Lower WARNS due to alignment issues on sparc64.

As of sam's r175206, arp builds cleanly at WARNS level 6, but the Makefile
was never updated. Also, clean up the macro that caused the warning in the
first place (no functional changes, just wrapped and reindented).

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

Reduce the WARNS levels in a couple of places so that we can enable
-Werror at higher WARNS levels like we did before gcc4 was imported.

Back out previous commit, it was unintentional.
Keep WARNS at 3 though the code does compile with WARNS=5 at least on i386

Replace ROUNDUP/ADVANCE with SA_SIZE

- Change several errx() calls that should have been err() calls.
- Handle empty ARP tables properly.
- Remove register keyword.
- arp(8) is WARNS?=4 clean, so mark it as such to avoid regressions.

allow teh -a option to work with the -d option
thus:
arp -d -a now flushes your arp cache.
also fix the -n option so that -an now works correctly.

Get rid of update. Make man page installation work with our scheme
(and rename a few in the process).

Remove stuff for building manual pages the old way.
