Sync apmd(8) with DragonflyBSD, bringing WARNS to 3

Reviewed by: ed (partial, long time ago)

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.

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

Mark APM manpages as i386-only.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Remove GCC'isms in CFLAGS.

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

Set the default manual section for usr.sbin/ to 8.

Don't forget to clean y.output. Most files generated by yacc are cleaned
automatically, but not this one.

Fixed some style bugs.

$Id$ -> $FreeBSD$

The apmd package provides a means of handling various APM events from
userland code. Using apmd.conf, the apmd(8) configuration file, you
can select the APM events to be handled from userland and specify the
commands for a given event, allowing APM behaviour to be configured
flexibly.

Have Fun!
