This makes the halt wrapper sysvinit compatible. It ignores several
command line switches which are not currently implemented; however,
those can be implemented if we need to do so.
This fixes https://github.com/openrc/openrc/issues/146.
Sysvinit shutdown has a default of single user mode, but openrc-shutdown
makes you choose a default action. Because of this, the shutdown wrapper
needs to pass --single to openrc-shutdown.
In the past, OpenRC was a hybrid of a centralized and file-scope
license/copyright structure.
I followed the instructions from the Software Freedom Law Center [1] to
convert to a Centralized structure where possible, for easier future
maintenance.

The posix equivalent of the type command is "command -v", so now we use
that. Thanks to Jonathan Callen <jcallen@gentoo.org> for informing me
wrt the fix.
On several machines, a file corresponding to AC adapter can be named
ADP1. The on_ac_power script checked for AC*, which does not match
ADP1, so the script always considered the adapter to be off.
