Remove $FreeBSD$: one-line .c pattern

Mark global functions and/or variables in apm(8) static where possible.

This allows compilers and static analyzers to do more thorough analysis.

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.

apm(8) is no longer linked to zzz(8), catch up.
(Fixes "zzz" clash in the whatis(1) database.)

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

Make apm(8) understand AC Line state 2 as "backup power".

Fix to not use 255, but instead use APM_UNKNOWN.
Compare things correctly against -1 or 0
Don't print any capabilities if unknown is returned from the kernel.

Factor out some duplicated code and fix some style(9) issues.

Submitted by: Liam J. Foy <liamfoy@sepulcrum.org>

Check for >= 255 since sign extension from byte to u_int sometimes makes
the value for "unknown" 0xffffffff. The underlying kernel drivers should
be updated to only return 255 but the ABI is used by too many userland
utilities.

Also, make this WARNS 6 compatible.

If mktime() or timegm() return -1, print out the resume timer value as
"unknown", rather than a conversion of -1 to a date/timestamp.

Fix a typo: "Managment" -> "Management".

Don't dump all information about apm when only asked to enable/disable apm
functions (-e and -h switches). This should make apm(8) self-consistent, as
for example -d enable|disable doesn't dump such info.

apm -d also needs a writable file descriptor.

When we're just reading info from the driver, attempt to open the apm
device read only so we can suppot a readonly apm device.

Cleanups, new options, and syntax changes w.r.t. the -e fiag I had just
added. This completes the addition of apmconf(8) features into apm(8),
and will be followed shortly by asmodai with a manpage commit.

Add the apm -e argument, which will toggle the "enabled" status of APM.

o Enable standby mode in apm utility. You need a newer kernel for this
functionality to work (however, the kernel changes were committed
to current at 1998/07/05 23:29:11 PDT).
o Enable setting of a timer for later wakeup. Note, not all APM
BIOSes support this for all modes (mine doesn't support waking up on
a timer from standby mode).
o Print out the APM capabilities, as reported by the BIOS.
o Report wake on ring indication. No way to enable/disable this, but
it is reported.
o update man page with above
o The output of this command has changed, so if you have a script that
parses its output, then you may need to rewrite it slightly.
o The code attempts to deal with older kernels than July 5, 1998, but
that part of the code isn't well tested.

Updated my e-mail addresses.

Output the estimated battery lifetime as "hh:mm:ss" along with
everything else. Add a "-t" option for outputting it in raw form.
Define and document the order in which raw values are printed when
more than one is requested on the command line.

Use warn rather than warnx to report errors opening the APM device.
Nit formatting fix

Use err(3). Typo in man page.

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

Remove an un-needed static declaration.

Re-write the driver to use getopt(), add the new display suspend
function of the kernel, and other assorted misc. cleanups.

Open up /dev/apm instead of /dev/apm0.

Add the '-s' flag to apm which returns the status of the APM support
(enable/disabled) now that the APM_GETINFO ioctl returns the necessary
information. Also, print out the status along with the other
information as the default behavior.

Remove trailing whitespace.

Fixed a #include to point to machine/apm_bios.h

The latest user-land changes from the author. I added a big warning to the
