Title: CPUTimes per cpu and CPUPercent

Some notes:

1. CPUTimes per cpu for Windows is left for somebody TODO. I don't know their API at all.
2. Darwin version is not tested as I have no way to test it. I've used the same method as for BSD, hopefully it will work. If not, I'll remove the Darwin commit.
