[Midnightbsd-cvs] src: src/usr.bin: Add cpufreq(1).

[laffer1 at midnightbsd.org]

Log Message:
-----------
Add cpufreq(1).  cpufreq is a utility to monitor the current cpu frequency easily.  powerd(8) and cpufreq(4) can change the frequency to conserve energy and it's useful to monitor this at times.

The sysctl interface is handy, but annoying for one off's like this.
