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

Reviewed by: ed (partial, long time ago)

Add battery state monitoring to apmd.

The new syntax available in the config file is:

apm_battery [0-9]+(%|[Mm) (dis|)charging { ... }

The stuff in the braces is the same as the existing case. nn% checks for
a certain percentage of life remaining and nnM checks for a cerain
number of minutes remaining. Specifying "discharge" means that you're
interested in knowing when the battery reaches a certain level while AC
power is off, "charging" the opposite.

The man page needs to be updated.

The code can be fooled. If you SIGHUP the daemon and the battery level
matches a rule it will be performed once per SIGHUP. If the battery
level matches a rule and you repeatedly apply and take away AC power,
the rule will be run once per occurance. This, however, is a feature.
:-) The code also only runs when select() times out, so getting APM
events more often than the timeout interval will result in the rules not
being run. These are things that remain to be overcome.

$Id$ -> $FreeBSD$

This commit was generated by cvs2svn to compensate for changes in r48730,
which included commits to RCS files with non-trunk default branches.

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!
