Newer devices have multiple power_supply devices in sysfs:
$ grep ^ /sys/class/power_supply/*/type
/sys/class/power_supply/AC/type:Mains
/sys/class/power_supply/BAT0/type:Battery
/sys/class/power_supply/ucsi-source-psy-USBC000:001/type:USB
/sys/class/power_supply/ucsi-source-psy-USBC000:002/type:USB
There are two "USB" Type-C ports than can supply power and both are
aggregated into the "Mains" power supply by the firmware. The "Battery"
also counts as a power supply, but is missing the online attribute.
The -f check with a wildcard pattern results in an error, when multiple
devices are present:
/lib/rc/bin/on_ac_power: line 21: [: too many arguments
When the power_supply class is registered, check for a "Mains" device.
Fixes#427.
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.
