7b708ac75b Add support for cpufreq to power_profile(8). Values for on/offline cpu 
frequencies are specified with performance_cpu_freq and economy_cpu_freq.
Of course, special values LOW and HIGH are also supported.  Also, remove
old throttling support.

ccc09458fa Change hw.acpi.cpu.cx_lowest to accept values in the form of C1, 
C2, ...  Update power_profile to use the new format.  Update the
man page to reflect this and give more info on Cx states.

3662033599 Add power_profile, a script that changes the ACPI CPU Cx idle state and/or 
the throttling state in response to line transitions.  Future plans
include adding support for CPU frequency changes.

Add a devd.conf entry for calling this script.

The default values for this are:
performance_cx_lowest="HIGH"       # Use HLT (C0) online
performance_throttle_state="HIGH"  # 100% (no throttling)
economy_cx_lowest="LOW"            # Use the lowest Cx state possible
economy_throttle_state="HIGH"      # 100% (no throttling)
