VRQ 0.94 release

VRQ 0.94 is released with the following changes

1. Remove duplicated code
2. Fix compilation issue with CONFIG_CPU_FREQ and CONFIG_IRQ_TIME_ACCOUNTING
3. Remove root_domain and sched_domain, which VRQ doesn't depend on. This reduce about 2k LOC of the scheduler code.

I have done some tests on SMT machine for the >100% regression issue, but for some kind of reason, I can't reproduce it, so now it is in the long-term watch list and let VRQ development going. Enjoy VRQ 0.94 for v4.10 kernel, :)

In next release, hrtimer and full no hz support are in the planning list.

code are available at
https://bitbucket.org/alfredchen/linux-gc/commits/branch/linux-4.10.y-vrq
