powerd - Initial load monitor and cpu frequency adjustment daemon
This daemon uses the hw.acpi.cpu.px_dom* sysctls to adjust the frequency
for all cpus based on the system cpu load.
For this initial implementation the daemon simply sets cpus to the maximum
frequency when the 1-second load exceeds 25% of one cpu and sets the cpus
to the minimum frequency when the 10-second load drops below 12%.
